Saat ini pemerintah Indonesia memiliki visi untuk menjadikan Indonesia sebagai poros maritim dunia. Nelayan merupakan salah satu pilar penting dalam pembangunan Indonesia sebagai poros maritim dunia, karena nelayan merupakan kelompok masyarakat yang setiap hari selalu berhubungan dengan laut. Nelayan membutuhkan beberapa informasi untuk mendukung aktivitas penangkapan ikan. Informasi tersebut antara lain adalah informasi daerah penangkapan ikan, informasi cuaca, informasi harga ikan, informasi dinamika laut. Selama ini, informasi-informasi tersebut berasal dari berbagai sumber. Sistem informasi nelayan pintar ini mengintegrasikan informasi-informasi dalam satu sistem berupa aplikasi berbasis android. Untuk mengenalkan teknologi ini kepada nelayan, maka pada tahun 2015 ini dilakukan sosialisasi sistem informasi nelayan pintar di 30 pelabuhan perikanan di Indonesia.

Hunting and gathering from the sea and seashore have played an important role in the rural economy of north Northumberland since early prehistory, with the collection of shellfish, hunting of birds and seals, trapping of crab & lobster, netting of salmon & herring and line fishing for cod & mackerel all important at various times. Today, the remaining fishing industry between Spittal and Bamburgh is focused almost exclusively on crab and lobster fishing from Lindisfarne, complemented by a modern oyster farm at Ross Point and the continuing, ad hoc collection of shellfish from the shore. Observations made amongst (and by) the fishermen of Lindisfarne have shown that the manufacture and use of creels for trapping crabs and lobster has changed gradually, through improvement, adaption to new materials and changing regulations since their introduction in the mid-19th century right up to the present. Particularly revealing have been the detailed recollections, humorous and analytical, of ex-fisherman Ralph Wilson, who began learning and working with his father in the early 1960s, a time of some change in the manufacture and use of crab and lobster creels. Ralph's father was a full-time fisherman who made all his own creels, as did all fishermen at that time and, indeed, until relatively recently when commercially made creels became popular.

The effect of preservative treatment on a secondary species of wood, Adina cordifolia
(Haldu) was studied. Panels were impregnated with creosote, an oil borne preservative, and
copper-chrome- arsenic (CCA), a water borne preservative, through immersion treatment. The
compressive stress parallel to grain of panels at various preservative retention levels was
assessed to find out the change in mechanical strength. An average reduction of 14%
compressive stress was noticed in CCA treated haldu panels and slight increase of 2 - 6%
was observed in creosote treated panels.

After the breaching of the Agger Tange in 1825 the fishing communities of the Western Limfjord in Northern Jutland (Denmark) went through a time of economic crisis. In response to these difficult circumstances two innovations were introduced: the sjægt (a new type of fishing vessel) and Danish seine fishing. Through case studies this paper examines the historical background and impact of these important innovations in times of crisis at the Western Limfjord.

Fishing is major source of food for the humanity and provides employment and economic benefits to large sections of the society. As a source of food it contributes about 20 percent of animal protein supply. At present the total world capture fishery production is around 95 million tonnes. About 70 percent of the fish production is directly utilised for human consumption while the balance 30 percent is reduced fish meal and used in animal feed production. In this paper presented during UGC sponsored Seminar on Emerging Trends in Aquaculture, Harvesting and Post Harvesting Technology, 7-8 March 2012, Department of Zoology, Marthoma College, Tiruvalla, modern trends in Fishing Technology are briefly discussed.

This open access book explores the histories and geographies of fishing in North Korea and the surrounding nations. With the ideological and environmental history of North Korea in mind, the book examines the complex interactions between local communities, fish themselves, wider ecosystems and the politics of Pyongyang through the lens of critical geography, fisheries statistics and management science as well as North Korean and more generally Korean and East Asian studies. There is increasing global interest in North Korea, its politics, people and landscapes, and as such, this book describes encounters with North Korean fishing communities, as well as unusual moments in the field in the People’s Republic of China, the Russian Federation and the Republic of Korea (South Korea). It addresses fish, fishing infrastructure, fishing science and fishing statistics and other non-human elements of North Korean and other nations’ developmental regimes as actors and participants within them as much as humans and their technologies. The book enables readers to gain extensive insights into the aspirations and practices of fishing in North Korea and its neighbours, the navigation of difficult political and developmental situations and changing ecological realities in a time of environmental and climate crisis familiar to many across the globe.

When people first lived in remote tropical seashores, they developed novel adaptations for living in these extreme environments, including the use of a specialised octopus lure device. The evidence for this fishing tradition now can be traced back as early as 1500–1100 BC in the Mariana Islands of Western Micronesia. New research has examined the artefacts of these compound lure devices, especially concerning the cut and drilled dorsum pieces of cowrie (Cypraea spp.) shells. Without this archaeological evidence, octopuses would have been undetected in the ancient deposits, and therefore a significant portion of past diet, innovative technology, and traditional practice would have been hidden from modern knowledge. The findings portray a broader and more realistic scene of ancient coastal communities, with implications beyond the confines of the specific island societies of the Pacific.

Abstract: Fishing experiments were carried out in Kotabaru of Indonesia to determine catching efficiency of double-twisted and triple-twisted multifilament trammel nets. A total of 10 nets were constructed with the same dimension and inner-outer mesh sizes (40-mm and 80-mm). Trials covered 160-net hauls/type with 1-hour submersion time. The shrimps were composed of Penaeus monodon, Penaeus merguensis, Metapenalis monoserus, Penaeus semiculatus and Parapenaeopsis sculptilis. A total of 142.8 kg shrimp comprises 84.46 kg (59.15%) for double-twisted and 58.34 kg (40.85%) for triple-twisted were collected over 16-daytrip sampling period, indicating double-twisted multifilament trammel net was 45% more efficient. The average weight of double-twisted (5.25±1.64 kg) was considerably higher than that of triple-twisted (3.65±1.41 kg) as well as total YPUE of double-twisted (1.056±0.02 kg) was considerably higher than that of triple-twisted (0.729±0.02 kg) (P<0.05). Some recommendations for improving performances and efficiency of trammel nets are made, for example, by inserting the additional bag collector along the lower part of the nets, placing selvedge between the lead line and the net or using underwater lamps associated with the net.

A somewhat enigmatic artefact appearing at three sites on the Western Cape coast, South Africa, are bone bipoints, termed ‘fish gorges’. These bipoints are found associated with large quantities of fish and shellfish remains in predominantly estuarine environments. They have a discreet appearance between 12 and 8 thousand years ago. Based on this association and their morphological similarity to North African and American fish gorges, these bipoints are presumed to have served the same purpose, although alternative functions have been proposed. Here I explore the appropriateness of these functional names through experimentation and use-trace analysis. Fishing produces few diagnostic use-traces, but based on the archaeological evidence it is possible to discount some of the alternative functions that have been proposed. We can infer the use of plant fibre lines on the bone bipoints.

ABSTRAK Perikanan pantai di Sulawesi Selatan umumnya didominasi oleh perikanan tradisional. Saat ini nelayan tradisional di daerah pantai berkompetisi dengan nelayan skala besar dalam melakukan operasi penangkapan ikan. Masalah yang dihadapi nelayan tradisional adalah meningkatnya harga bahan bakar minyak, biaya operasional, terbatasnya kemanpuan manajemen, kebijakan perikanan dan kondisi cuaca yang sulit diprediksi. Dalam rangka mengurangi masalah tersebut maka pemberdayaan masyarakat nelayan pantai, subsidi bahan bakar minyak, kebijakan untuk melakukan introduksi teknologi baru menjadi sangat penting untuk dilakukan. Transfer teknologi penangkapan ikan ramah lingkungan kepada kelompok nelayan di Teluk Bone Sulawesi Selatan sekarang ini merupakan salah satu solusi untuk menangani masalah tersebut. Di bawah program grass-root partneship, Universitas Ilmu dan Teknologi Kelautan Tokyo dan Universitas Hasanuddin bekerjasama melakukan transfer teknologi perikanan set net di Teluk Bone Sulawesi Selatan yang dimulai tahun 2007 untuk periode 3 tahun. Tulisan ini membahas introduksi set net di Sulawesi Selatan yang aktivitas meliputi seleksi lokasi, persiapan, proses penangkapan dan evaluasi hasil tangkapannya. Diharapkan tulisan ini dapat menjadi referensi dalam pengembangan set net sebagai strategi pengembangan manajemen perikanan pantai di Indonesia atau daerah lainnya.

The study of fishing tackle is an innovative research avenue which is improving our understanding of one of the most important past economic activities: fishing. This book is the first attempt to approach this issue in the region known as Fretum Gaditanum, were over a thousand pieces of evidence pertaining to fishing tackle have been inventoried. In these pages, the reader will find the typo-chronological classification of the material, which follows a diachronic discourse spanning the Phoenician-Punic period and Late Antiquity; special emphasis will be laid on the morphological-typological changes undergone by these artefacts and technological change over time. In this way, a comprehensive picture of the fishing arts practiced in the environment of Gades during Antiquity will be drawn, and the corpus will be compared with those found in other Atlantic and Mediterranean regions.

Zusammenfassung – Die hier vorgestellte Dissertation befasst sich mit Holzartefakten von endmesolithischen und frühneolithischen Küstensiedlungsplätzen an der südwestlichen Ostseeküste. In diesem Artikel werden die Geräte zum aktiven und passiven Fischfang präsentiert,
um die Bedeutung des Fischfangs für die Subsistenz der Menschen während der Phase der Neolithisierung im Verbreitungsgebiet der der Ertebølle-Gruppen und der nördlichen Trichterbecherkultur zu belegen. Die Untersuchung der Aalstecher, Reusen, Fischzäune, Einbäume und Paddel ermöglicht Schlussfolgerungen über deren Herstellungs- und Funktionsweise sowie deren typische Charakteristika.
Insbesondere wird die bisher nur in der Ertebøllezeit nachgewiesene Bauweise der Korbreusen aus Spaltstäben des Roten Hartriegels (Cornus sanguinea) und des Schneeballstrauches (Viburnum opulus) vorgestellt. Die Ergebnisse der dendrologischen Analysen zeigen
darüber hinaus den damaligen hohen technischen und handwerklichen Standard. Weiterhin können die gezielte Produktion von Holzrohstoffen und damit kleinteilige Eingriffe in die Waldvegetation nachgewiesen werden. Die intensive Nutzung der stationären Fischfanganlagen impliziert das Zusammenwirken einer größeren Gruppe von Menschen und eine stabile soziale Ordnung. Mit dem Beginn des Frühneolithikums (FN I a) ist noch keine deutliche Veränderung des Siedlungssystems oder der Subsistenzwirtschaft zu erkennen.

Abstract
Very few studies have been conducted to analyse physical and mechanical properties of fishing hooks. The present work is an account of a
study carried out on five major brands of number seven round bent fishing hooks available in India, which are used to harvest tuna and medium
sized fish resources. We have selected three imported and two indigenous brands of fishing hooks. The dimensional characteristics and unbending
force as tensile load for deformation of the hook bend equal to its bite length were investigated. The mechanical strengths of the fishing hooks
studied were highly varied and brand IB-1 recorded the highest unbending force of 275.9 N. It was found that the unbending test method
employed to analyse the mechanical strength of fishing hook in this study is in agreement with the actual performance by the fishing hooks in the
field and this test could be effectively used to evaluate mechanical strength of fishing hooks.

Fishhooks are among the most widely distributed and frequently excavated artifacts in
Eastern Polynesia. Their analysis contributes to understanding such wide-ranging topics
as Polynesian migration and inter-island contact, subsistence and resource utilization
and depression, and the establishment of relative chronologies. Emory, Bonk, and Sinoto
conducted the first systematic analysis of Polynesian fishhooks in 1959. Continued work
by Sinoto laid the groundwork for East Polynesian fishhook studies and their utility
in comparative analysis and chronological applications. This paper reviews previous
Polynesian fishhook arrangements and suggests possible variables for the construction of a
function-oriented classification. A selection of these variables are applied to the collection
of fishhooks excavated by Robert Suggs on Nuku Hiva, Marquesas Islands, revealing
a more nuanced picture of spatiotemporal trends in fishhook size and morphology than
previously established.

Length frequency of sardine, Sardinella longiceps (Valenciennes), caught in gill nets with
mesh size of 32, 34, 36, 38 and 40 mm operated off Cochin (Kerala) was recorded. Using
this, the selectivity parameters of the nets of these mesh sizes were assessed. The size range
of S. longiceps caught was 12 to 20 cm. The estimated selection factors ranged from 4.56 to
4.67 and the selection lengths ranged from 14.7 to 18.7 cm. Gill nets with mesh size less
than 34 mm did not facilitate the escapement of S. longiceps which had not attained the
stage of first maturity.

"This thesis examines the fishing methods used by the pre-contact Native inhabitants of the Blue Water Bridge South site (AfHo-7) through ethnographic and archaeological research, the fish fauna remains and the fishing related artifacts excavated from the site.
From these lines of evidence it was determined that spring spawning fish species such as lake sturgeon and walleye were being harvested with the use of harpoons and spears for the former, and fish nets and leisters for the latter. Evidence also strongly suggests the existence of an intensive summer fishery that used nets for the capture of spawning freshwater drum as well as a spring and summer opportunistic fishery that employed fishhooks and nets. This site was inferred to have followed a spring early-summer macroband settlement pattern with perhaps a minor fall occupation that may have involved fishing for spawning lake whitefish. Based on the overall pattern of settlement and subsistence inferred for the Blue Water Bridge South site and comparisons with other Middle Woodland sites within the central Great Lakes region, it was concluded that the Middle Woodland pattern of settlement and subsistence was highly variable and influenced by both environmental variables and human choice."

Use of Patagonia's forests by hunter-gatherers remains relatively poorly understood. Regional archaeological records indicate initial forest colonization during the middle Holocene, infrequent use until late prehistory, and, even then, fairly sparse occupation, likely in conjunction with use of the adjacent steppe. Recent excavations at Río Ibáñez-6 West in Aysén, Chile, provide a new perspective for understanding the prehistoric use of Patagonian forests, particularly regarding timing of the initial occupation and the potential for development of a forest-specific adaptation. We provide chronological, lithic, archaeofaunal, and macrobotanical data that show use of the Ibáñez River valley at least a millennium earlier than previously documented. These data indicate increased dietary breadth in late prehistory, supporting the established hypothesis that the valley became a closed system at that time. From our data we develop hypotheses regarding prehistoric forest use in Aysén that have implications for the broader understanding of the suitability of the forest for prehistoric human foragers.

En este trabajo presentamos un estado de la cuestión sobre los anzuelos de pesca en la península ibérica. Para ello realizaremos un análisis diacrónico desde las primeras evidencias que se conocen en el registro arqueológico prehistórico hasta época medieval. Se tratará de anali-zar cómo ha sido su evolución a lo largo de la historia, definiéndose los principales hitos tecnológicos que han ido produciéndose hasta llegar a configurarse el modelo de anzuelo que conocemos en la actualidad, y conside-rándose, al mismo tiempo, cuáles son aquellos rasgos morfo-tipológicos que han perdurado/desaparecido y cuáles han sido transformados/sustituidos. Todo ello nos permitirá valorar aspectos históricos de gran importancia como pueden ser el origen geográfico de las innovaciones y su difusión a escala atlántico-mediterránea a través de posibles fenómenos de interacción cultural. Palabras claves. Anzuelo; hueso; metal; sistema de suje-ción del sedal; arpón. Abstract In this work we introduce a state of the question about fish hooks in the Iberian Peninsula. In order to do so, we will carry out a diachronic analysis from the first evidences known in the prehistoric archeological record until the Medieval time. We will attempt to analyze how they have evolved throughout history, defining the main technological milestones that have been occurring until it turns into the fish hook model we know now. At the same time, we will consider which morphotypological characteristics have persisted/disappeared and which ones have been transformed/replaced. Taking all this into account, we will assess very important historical aspects, like the geographical origin of innovations and their dissemination in the Atlantic and Mediterranean areas thanks to possible cultural.

This article collects and analyzes the literary, archaeological, epigraphic and comparative evidence for fishing with fire, arguing that the range of techniques and technologies employed in antiquity is fundamentally similar to that attested in the early modern Mediterranean and that such fisheries were conducted on a large enough scale that the attendant demand for and trade in torchwood played an important role in the utilization of forest resources.

We still lack basic knowledge of the intensity and character of fishing as subsistence among the Stone Age populations of the northeast shores of the Baltic Sea. In locations where direct evidence of fish utilisation is insufficient, various forms of indirect evidence play an essential role. Generalisations about the importance of fishing are mainly based on shore-bound site locations, fragmentary burnt fish remains, and fishing-related artefacts recovered at archaeological sites. The remains of stationary wooden fishing structures preserved in wetland conditions have not been properly utilised previously in Finland to study prehistoric subsistence practices and diet. The interplay between the archaeological and ethnographic materials is well-grounded, because similar structures have been used for several millennia. This paper combines the wetland archaeological data, fish remains, and ethnographic analogy based on environmental and climatic considerations to examine the fishing methods and subsistence base among the Middle Subneolithic (non-agricultural Neolithic) populations of northwest Finland c 3000 calBC. Several factors, including site location, requisite woodworking skill, the quantity of the wooden structures, and the labour contribution allocated to fishing all underline the high significance of aquatic resources for the hunter-fisher-gatherer populations occupying the mouth and the banks of the Iijoki River during the mid-Holocene productivity peak of the Baltic Sea.

Vital Diplomacy offers an ethnographic interpretation of the perpetual ritual life of the Enawenê-nawê, an indigenous Amazonian people who live on the Juruena river, where the Brazilian government is installing a series of hydroelectric dams. Why is the Enawenê’s ritual life so constant and so vital? And how does it continue to generate health and prosperity when hydropower developments threaten its very foundations? The answer lies in the diplomatic nature of Enawenê-nawê ritual, which continually contains and diverts the threat of violence by reconciling predatory spirits, coordinating clan and gender divides, and channeling foreign relations and resources. In this highly gendered account, female activities like cookery, garden, care and craft work are analysed alongside male fishing, flute-playing, and performance. On the basis of an innovative theorisation of diplomacy, and based on comparisons that highlight the specificities of Amazonian fisher-agricultural societies, the book disrupts the popular view of Amazonian peoples as warriors and hunters driven by predatory ideologies.
