The whale shark is an ideal flagship species for citizen science projects because of its charismatic nature, its size, and the associated ecotourism ventures focusing on the species at numerous coastal aggregation sites. An online database of whale shark encounters, identifying individuals on the basis of their unique skin patterning, captured almost 30,000 whale shark encounter reports from 1992 to 2014, with more than 6000 individuals identified from 54 countries. During this time, the number of known whale shark aggregation sites (hotspots) increased from 13 to 20. Examination of photo-identification data at a global scale revealed a skewed sex-ratio bias toward males (overall, more than 66%) and high site fidelity among individuals, with limited movements of sharks between neighboring countries but no records confirming large, ocean basin-scale migrations. Citizen science has been vital in amassing large spatial and temporal data sets to elucidate key aspects of whale shark life history and demographics and will continue to provide substantial long-term value.

Photo‐identification and conventional tagging were used to estimate population size and structure of the whale shark Rhincodon typus near Holbox Island, Mexico. From 2005 to 2008, photographs of spot patterns behind the last gill slit and in a lateral view on the left side of each animal were used to identify individuals. Additionally, 578 R. typus were tagged using conventional marker tags. Of these and the 350 R. typus that were identified from 1184 photographs, 65% were male; 27%, female and 8%, indeterminate sex. Photographed R. typus ranged in size from 2·5 to 9·5 m total length. Size was bimodal with a large peak at 6 m and a smaller peak at 7 m. Photo‐identification showed that there was considerable loss of marker tags. Few of these remained on the animals for more than a year, so that interannual re‐sights using tagging could not be used in population modelling. Forty six interannual re‐sightings were found in the photographic library; the interval between these re‐sighting...

Nature-based tourism, such as whale watching and swimming with whale sharks, is rapidly growing worldwide. Although there is no clear classification, whale watching is often referred to as ecotourism or sustainable tourism. However, one of the key principles of true ecotourism is that it promotes, among other things, the generation of environmental education and awareness. The purpose of this research was to evaluate the effect of tourism activities with charismatic species in tourists' environmental consciousness. The study was carried out in three stages via surveys to participants of two main activities (snorkeling with whale sharks and gray whale watching) in Baja California Sur, Mexico: 1) one before the activity where socio-demographic, circumstantial variables, and initial environmental awareness and pro-environmental behavior were measured; 2) one immediately after, evaluating aspects of the experience and awareness in the short term, and, 3) Four months later via e-mail to evaluate environmental consciousness in the long term. A total of 542 surveys were obtained in the first two stages, and 200 surveys in the third stage. A Structural Equation Model analysis was performed to test causal relationships between the activities and environmental consciousness. Our results show that the experience with a charismatic species had a significant and positive effect on short-term environmental awareness. However, there was no significant effect of the experience on their long-term environmental consciousness. Implications for the actors involved in nature-based tourism activities are discussed, highlighting the need to implement globally used strategies but applying them in the local context.

Indonesia has a variety of local tourist destinations whose culture cannot be compared with other tourist destinations. The purpose of this article is for those of you who want to know more about the culture and uniqueness of Sade Village. The benefit of writing this article is that it can be used as a suggestion and contribution to the development of the tourist village of Sade village in central Lombok. Lombok is an island in the Lesser Sunda Islands or Nusa Tenggara, separated by the Lombok Strait on Bali Island to the west and the Alas Strait on Sumbawa Island to the east. The island has an almost round shape with a kind of "tail" on the southwest side, is about 70 km long and has an area of about 5,435 km². The traditional veil or traditional house of the Sasak people is still preserved in Sade village, Central Lombok province, where this traditional house is the residence of people with middle to upper economic status. The design of this house consists of two straw bales and a veranda called Sesankok. It's just that this bale is equipped with a sambi to help you store food and other items. Judging from Sad's tourism development strategy, local customs also have a negative impact on the development of Sad tourism village. Because local customs are religious beliefs that tourists must obey. Therefore, the government must respect local customs in developing the Sade tourism area. The development of the Sade tourism village must be done properly and correctly so as not to damage the existing local culture. Tourists will be included in local customs while in the Sade tourist area. For example, the local influence of religious practices on the development of Sade tourism also needs to be communicated to Sade tourism residents.

This research aims to understand the sea as a cultural space within the context of the Lamalera shing community on Lembata Island, Indonesia. The Lamalera community is a fishing community with the privilege of catching whales, dolphins, and manta rays-species that are protected. The human relationship with the marine environment is a complex model, encompassing various aspects such as culture, economy, social, political, and spiritual dimensions. This study reveals cultural practices that have developed around the sea, including myths, customs, shing traditions, maritime trade, and the utilization of marine resources. Furthermore, this research also identi es the role of the sea in shaping the cultural identity of the Lamalera community, including livelihoods, beliefs, and unique cultural practices. Through an interdisciplinary approach involving history, anthropology, sociology, and cultural studies, this research complements previous studies on the sea as a cultural space. The results of this research show that the Lamalera community has a close and unique relationship with the sea through whale hunting practices and other shing activities. Their highly intensive interaction with the sea as their sole source of livelihood forms the identity of the Lamalera community as a traditional whale hunting shing community (aboriginal subsistence whaling).

2024, Qatar Whale shark catalogue

This is the first official Qatar Whale Shark Catalogue of over 330 whale sharks identified from underwater, aerial, and boat-side photos taken in the 2022 and 2023 seasons of summer whale shark feeding aggregations. Each shark was given a Qatar identification (ID) number, some with gender and/or sex as well as body length measured from laser photogrammetry and measured using a boat of known size as a reference. To distinguish the gender, the presence of claspers indicates a male, and the absence suggests a female. This catalog can be used as a reference for the Gulf nations to find if there are any local whale shark matches in the catalog as possible links between Qatar and each Gulf nation. And for long-term population trend and structure studies.

The Arabian (Persian) Gulf is home to a wide range of marine animals, including the endangered whale shark, and is impacted by a variety of environmental factors. Between June and December 2022, this study evaluated the environmental factors, qualitative and quantitative analysis of zooplankton groups, and their abundance in the Arabian Gulf's whale shark zones that are located in the Al-Shaheen Oil Field Ecosystem. The study discovered that the Gulf's high temperature, salinity and alkaline pH levels create an ideal paradoxically home for zooplankton, a crucial source of food for higher trophic levels. Environmental parameters, such as dissolved oxygen showed an increase when chlorophyll-a peaked, indicating better phytoplankton productivity. Additionally, the increasing chlorophyll-a showed an increase during the peak whale shark sighting months, indicating that large zooplankton population was consumed. In contrast to the increasing chlorophyll-a levels, the study area demonstrated characteristics of an oligotrophic environment. The richness and evenness of the zooplankton population demonstrated the significant diversity present in the area, and the biomass data revealed the significant energy accessible to higher trophic levels. Taxa were shown to be clustered based on their ecological relationships and feeding habits using multivariate analysis. To develop a more thorough knowledge of the marine environment of the Gulf, the research perspectives advise integrating phytoplankton, neuston, zooplankton, and whale shark observations, as well as thorough taxonomic analysis.

A new species of deep-water dogfish shark, Squalus hima sp. nov. is described herein from the Arabian Sea, off southwest India. This species has been largely misidentified with S. mitsukurii and S. lalannei. However, morphological, meristic, morphometric evidence support it to be a separate and undescribed species. Squalus hima sp. nov differs from other species by the number of precaudal vertebrae, total vertebrae, teeth count, trunk & head heights, fin structure and fin colour. The morphological, morphometric and meristic characteristics of the specimen are provided in the present paper. The new species is compared with other species in the genus occurring in Indian Ocean.

Phytoplankton community in Nuevo (GN) and San José (GSJ) Gulfs is dominated by diatoms and dinoflagellates. Species that are potential producers of domoic acid (DA) of the genus Pseudo-nitzschia are frequent components of phytoplankton in these gulfs. The dinoflagellate Alexandrium tamarense, a producer of paralytic shellfish poisoning (PSP) toxins, has been found in this area showing a tendency to produce blooms in spring. Copepods are the most abundant group in the mesozooplankton community both in GN and GSJ, its maximum densities occurring during spring after the spring phytoplankton bloom. Recent studies have demonstrated that the southern right whale Eubalaena australis feeds during its stay in GN and GSJ. Still, feeding in these gulfs could be dangerous for the whales due to the recurrent toxic phytoplankton blooms in this area during spring. The effect of toxins on whales´ health has been postulated to be one of the causes of the calves´ mortality observed in Península Valdés in the last years. The aims of this Ph. D. Thesis were i) to study seasonal variations in food availability in qualitative and quantitative terms for individuals of E. australis, and ii) to analyze biotoxin transfer from phytoplankton-producing species to vectors in mesozooplankton and from them to whales. During the annual cycle studied (December 2014-December 2015 in GN and January 2015-January 2016 in GSJ) phytoplankton in GN as well as in GSJ was dominated by diatoms and dinoflagellates. Toxic microalgae species were more frequent during spring, including a bloom of P. australis in October in GN. Mesozooplankton in GN was dominated by copepods and cladocerans while in GSJ it was dominated by copepods. In both gulfs copepods were associated to phaeopigments and salinity whereas cladocerans were positively correlated to temperature. Mesozooplankton abundance and biomass were in general low during the season of whales (winter and spring). Interestingly, a remarkable mesozooplankton biomass was observed towards the end of winter in GN, a total of ~17-20 whales being recorded filtrating seawater. The main preys for E. australis were calanoid copepods, Munida gregaria zoea larvae, Euphausia lucens caliptopis, furcilia, juveniles and adults as well as several ichthyoplankton organisms. DA was also detected in the water column, in the plankton samples and in faecal material from live specimens of E. australis. This study demonstrates for the first time that the southern right whale is exposed to DA through feeding in Península Valdés and that copepods could be the principal vector of this toxin. It was nonetheless not possible to verify the transfer of PSP toxins through the food web nor was it possible to show that this transfer could affect whales.

Botubarani in Gorontalo, on the northern coast of Tomini Bay and Labuhan Jambu in Teluk Saleh, Sumbawa recently became whale shark tourism destinations in Indonesia. Both sites offer visitors opportunities to interact with whale sharks, either watching from canoes or snorkelling and diving. In this study, we investigated the status and ecotourism potential of whale shark watching as a form of marine wildlife tourism development in eastern Indonesia by examining the existing operations in both sites. Data were collected using questionnaires administered to local community members and visitors to understand their perceptions, and how this opportunity was valued. Secondary data were collected to explore and understand influencing factors. Findings revealed that whale sharks commonly emerge near bagan lift-nets and other interactive areas as a response to the presence of their favorite prey, anchovies, and rebon shrimp. In general, whale sharks most commonly visit bagan lift nets and can be found in the interaction areas in the morning and stay for couple of hours before swimming away to deeper waters. Out of 119 community respondents in Labuhan Jambu village (Teluk Saleh) and Botubarani, Gorontalo, 80.7% knew about the occurrence of whale sharks in their locality. Of the 111 visitor respondents, 67.6% knew about the whale shark watching sites from word of mouth. The study results also suggest a correlation between chlorophyll-a concentration, anchovies, rebon shrimp and whale sharks. Regarding management approaches to this type of tourism, a local community-based management model is strongly recommended, with 87.4% of respondents showing interest in this approach. The roles and responsibility of local government in developing such tourism is very significant, especially with respect to facilitating appropriate competency within the local community throughout training and education, as suggested by nearly 26% of respondents.

Fishing has a major impact on the biodiversity of elasmobranchs, a diverse and ancient group of fish. The illegal trade of products derived from endangered species is widespread and many times concealed by both deliberate and inadvertent mislabeling. In groups where data is sparse, such as guitarfishes, it is unknown which species are at a higher risk of extinction due to illegal trade. Brazil is currently one of the world's largest market for elasmobranch products, but it is uncertain whether the current regulatory measures are effective across all commercial sectors. Here, we applied molecular phylogenetics to identify the species sold as elasmobranchs in Rio de Janeiro. Products labeled as "shark", "ray" and "guitarfish" were sampled from fishmongers, supermarkets, restaurants and street markets (n = 221). Over 60% of the samples were derived from threatened species, reaching 90% in guitarfish and 100% in ray products. The endemic and critically endangered Pseudobatos horkelii was the only authentic guitarfish among all samples labeled as such (n = 75), all others were identified as threatened/endemic rays (Atlantoraja castelnaui, A. cyclophora) or sharks (Squatina guggenheim, S. occulta). S. guggenheim was also detected among the products labeled as "sharks" (n = 113), as were five other endangered shark species: Carcharhinus falciformis, C. signatus, Isurus oxyrhinchus, Sphyrna zygaena and S. lewini. While no mislabeling was observed in supermarkets, the prevalence was high in local trade, indicating that regulatory and awareness-raising measures must be adapted to this economically and socially important sector.

Muestreos rutinarios del plancton de Bahía de Banderas permitieron detectar dos eventos de Mirionecta rubra y Pseudo-nitzschia sp durante 2011. Para identificar las poblaciones de zooplancton más representativas asociadas con el primer evento, se recolectaron catorce unidades de muestras a lo largo de la zona costera, incluyendo dos réplicas sobre la mancha. Los arrastres se hicieron con una red estándar de 40 cm de diámetro de boca y malla de 335 µ. Las máximas abundancias de zooplancton no se registraron en la zona de mayor coloración. De manera contrastante, la recolección de una muestra de agua durante el segundo evento hizo evidente una elevada abundancia de zooplancton que alcanzó un valor de 5 millones de ind/m 3 , un valor inusual en zooplancton epipelágico del Pacifico mexicano. Esta abundancia fue al menos tres órdenes de magnitud más alta que las registradas en otros parches reportados en diversas zonas costeras del Océano Pacifico. La estructura del zooplancton de ambos eventos fue dominada por el copépodo Acartia tonsa. Eventos intermitentes persistieron localmente hasta finales de abril, cuando se detectó el varamiento de peces globo en las playas. La secuencia de estos eventos parece estar asociada con la ocurrencia de surgencias previamente reportadas en la región de Cabo Corrientes.

Considerable research exists on the life history traits, evolutionary history, and environmental factors that shape the population genetic structure of marine organisms, including sharks and rays. Conservation concerns are particularly strong for this group as they are highly susceptible to anthropogenic stressors due to a combination of life history traits including late maturity and low fecundity. Here, we provide a review and synthesis of the global phylogeography of sharks and rays. We examined existing data for 40 species of sharks belonging to 17 genera and 19 species of rays belonging to 11 genera. Median joining haplotype networks were constructed for each species for the mtDNA cytochrome C oxidase subunit I (COI), and an Analysis of Molecular Variance (AMOVA) was conducted to understand patterns of genetic diversity and structure across the three major ocean basins-the Indian, Atlantic and Pacific Oceans. Haplotype networks showed very shallow coalescence in most species, a finding previously reported for marine teleosts. Star topologies were predominant among sharks while complex mutational topologies predominated among rays, a finding we attribute to extremely limited dispersal in the early life history of rays. Population structuring varied amongst species groups, apparently due to differences in life history traits including reproductive philopatry, site fidelity, pelagic habitat, migratory habits, and dispersal ability. In comparison to reef-associated and demersal species, pelagic and semi pelagic species showed lower levels of structure between and within ocean basins. As expected, there is variation between taxa and groups, but there are also some broad patterns that can guide management and conservation strategies.

We always thought that elasmobranchs inhabit marine environments, but this is only partially true. About 5% of known elasmobranch
species are the freshwater compared to 40% of teleost species. A systematic checklist is available for Indian freshwater
elasmobranches with names and IUCN status. A total of 13 species belonging to 3 orders, 3 families and 10 genera were enlisted
from secondary data. Euryhaline and obligate species include sharks as Carcharhinus, Glyphis (Carcharhinidae), Chiloscyllium
(Hemiscylliidae), sawfishes or Pristis (Pristidae), stingrays or Himantura (whiprays) and Pastinachus (cowtailed rays) (Dasyatidae).
We focus on distribution, feeding habits, threats and conservation. Freshwater excursions are relatively rare in extant elasmobranchs
than other groups of fish. The low growth rate is probably due to late age at maturity and low fecundity, long gestation periods, slow
growth and productivity (small, infrequent litters), high natural survivorship for all age classes and long life. Despite this, some
species of freshwater elasmobranchs can tolerate and even thrive in freshwater.

The competitive exclusion principle establishes that the coexistence of closely related species requires a certain degree of resource partitioning. However, populations have individuals with different morphological or behavioral traits (e.g., maturity stages, sexes, temporal or spatial segregation). This interaction often results in a multi-level differentiation in food preferences and habits. We explored such resource partitioning between and within three batoid species: Hypanus dipterurus, Narcine entemedor, and Rhinoptera steindachneri in the southern Gulf of California, Mexico, using a combination of stomach content (excluding R. steindachneri) and stable isotope analyses. We found a clear differentiation between H. dipterurus and N. entemedor, where the latter exhibited more benthic habitats, supported by a greater association to infaunal prey and higher δ13C values. Though the degree and patterns of intra-specific segregation varied among species, there was a notable different...

2024, Animal Biotelemetry

Background: Attachment of towed, floating satellite tags to large marine organisms has provided scientists with a wealth of information on the movements of these species. These tags generally are not programmed to detach at a particular time, yet are often prone to detachment by natural means after only a few days or weeks. It is important to be able to distinguish between the tracks provided by a detached, floating tag, and one that is attached to the subject. To this end, we placed three SPOT-5 and one SPLASH tag on large female whale sharks at Darwin Island (Galapagos Islands), and compared their tracks with those of two floating SPOT-5 tags released at the same site. We present a set of criteria to determine whether a towed satellite tag encased in a float is still attached to the study organism. Results: None of the whale sharks remained in the vicinity of the island. Three of the tracks lasted 31 to 48 days, yet one shark was tracked for 167 days. This was the first recorded bona fide homing migration of a whale shark, travelling 1,650 km west then returning to Darwin four months later. Two other sharks also returned to Darwin. We found that at the time of detachment, a clear change in the daily timing and quality of transmissions became evident. This, in conjunction with daily depth and temperature summaries, and knowledge of currents and the biology of the subject, can be used to justify endpoints on tracks that continue to accrue positions as the tag floats with the currents. Conclusions: The data provided by floating tags is sufficiently distinct to be able to determine a detachment date. After detachment, daily transmissions are received in the first hours of the day after midnight (Coordinated Universal Time), the location quality of the transmissions is consistently high, and temperature or depth summaries are consistent with surface records. Prior knowledge of subject behavior and general ocean circulation patterns in the region reinforces the ability to determine detachment date. In some cases, after a prolonged period of more than three or four weeks, the detection pattern may change, yet caution should be exercised in assuming that the tag is, after all, still attached.

We used photo-identification data collected from 2003 through 2009 to estimate population structure, site fidelity, abundance, and movements of this species along the west coast of the Gulf of California to make recommendations for effective conservation and management. Of 251 whale sharks identified from 1784 photographs, 129 sharks were identified in Bahía de Los Ángeles and 125 in Bahía de La Paz. Only juveniles (mostly small) were found in these 2 bays. At Isla Espíritu Santo, we identified adult females; at Gorda Banks we identified 15 pregnant females. High re-sighting rates within and across years provided evidence of site fidelity among juvenile sharks in the 2 bays. Though the juveniles were not permanent residents, they used the areas regularly from year to year. A proportion of the juveniles spent days to a month or more in the coastal waters of the 2 bays before leaving, and periods of over a month outside the study areas before entering the bays again. Additionally, 26 juveniles migrated between Bahía de Los Ángeles and Bahía de La Paz. Pregnant females aggregated for a few days in oceanic waters at Isla Espíritu Santo and Gorda Banks, but no re-sightings occurred between years. The presence of pregnant females and small juveniles (2 m) suggests the presence of a nursery near the 2 far offshore areas. These 4 localities are important for conservation of this endangered species.

This study seeks to understand the impact of the tourism crisis due to the Covid-19 pandemic in the Kaliurang Tourism Area and the emerging vulnerabilities for tourism actors who make tourism their sole livelihood. To understand these conditions, pre-eliminary research was carried out as part of a series of research on tourism and COVID-19. This research was conducted by using qualitative methods from April to October 2021. The results of this pre-eliminary research clearly show that tourism actors in Kaliurang are experiencing a slump due to the COVID-19 pandemic. Tourism, which is the main source of living, is in fact very vulnerable to a prolonged crisis. The impacts and risks that arise in Kaliurang are clearly seen in the economic and socio-cultural sectors. As an effort to survive the tourism actors in Kaliurang are trying to respond to this condition individually and in groups. However, the responses that arise are not only positive but also negative, such as friction and con...

The goal of our study was to evaluate genetic diversity of whale sharks (Rhincodon typus) observed in Cenderawasih Bay, Indonesia, compared with that of whale sharks elsewhere in the Indo-Pacific region using mitochondrial DNA. We collected tissue samples from 31 whale sharks, virtually all adolescent males, in Cenderawasih Bay and then extracted, amplified, and sequenced mitochondrial DNA from the cytochrome oxidase I (COI) gene of the mtDNA COI gene. Genetic diversity of whale sharks in Cenderawasih Bay was low. We detected seven haplotypes and estimated haplotype diversity at 0.187 and nucleotide diversity at 0.002. The average number of pairwise differences was 0.254. These data suggest that the whale sharks that we encountered in Cenderawasih Bay were closely related and less related to whale sharks elsewhere in the Indian Ocean and western Pacific Ocean.

Management of whale shark Rhincodon typus populations is hampered by a lack of information on the range travelled by individual whale sharks. This applies particularly in Southeast Asia where the whale shark is increasingly used in commercial trade and for ecotourism. In this study an investigation of the movements of individual whale sharks from the greater Sulu Sea region was initiated using satellite telemetry. The movements of six sharks were monitored from 7 to 128 days. Two sharks travelled distances of 4567 and 8025 km. Both sharks moved through multiple political jurisdictions, con®rming the need to manage the populations on a multilateral or regional level.

The emergence of Coronavirus Disease 2019 or Covid-19 has caused various turmoils in human life, including dealing a crushing blow to the tourism sector. Social restriction policies that make it difficult for people to travel have significantly impacted the decline in tourism activity. The existence of a travel ban has made the level of foreign and domestic tourists visit very drastic. This fact shows that tourism can return to work but with the emergence of new needs from tourists. Therefore, it is necessary to adopt new tourism businesses that involve all tourism stakeholders in Indonesia. In other words, business actors must adapt to changes in the tourism market, such as changes in the demands of tourism consumers, so that tourism business actors need to change their business behaviour from business behaviour before Covid-19. The study aims to analyze the entrepreneurial behaviour of the tourism sector during the Covid-19 pandemic. The research was conducted by studying the phenomenon and entrepreneurial behaviour of the tourism sector in three tourism cities in Indonesia, namely Solo, Labuan Bajo, and Bandung. The three cities represent three tourist attractions, namely culture (Solo), beaches and sea (Labuan Bajo) and mountains (Bandung).
