The objective of this study was to describe the socioeconomic aspects of commercial fishers of edible fish who work in the municipality of Barcelos, in the middle Negro River region, as well as to highlight the scenario of the fishing activity from the point of view of the fishers. The information was collected between January and December 2016 in the municipality of Barcelos, state of Amazonas, via semi-structured questionnaires. Most interviewees were male (71.14%), aged between 18 and 82 years and a mean age of 48 years. With a low level of education, 45.0% had only incomplete elementary education and 15% were illiterate. The fishing tackle most used by fishermen was the gillnet, especially by urban fishermen (70%). Among the fishing sites, the main one was the Demeni River (50%). Commercial fishing for edible fish in Barcelos f...

However, studies regarding the local ecological knowledge of workers in this activity are still incipient. In view of this, we have studied and explored the local ecological knowledge of artisanal fishers who specialize in the capture of fish for the aquarium trade in the middle part of the Negro River basin and investigated issues related to the ecological aspects of the fish species that are targeted by this trade in the region. Methods Therefore, we conducted semi-structured interviews and applied questionnaires to artisanal fishers of ornamental fish (N = 89), from the municipality of Barcelos, from January to April 2016. Results In total, 41 popular names were cited, which correspond to four ethnocategories and 10 families. The main species were Paracheirodon axelrodi (12.5%), Hemigrammus bleheri (8.3%), Ancistrus dolichopterus (6.4%), Symphysodon discus (5.3%), ...

O objetivo do presente estudo foi avaliar a qualidade da água e os impactos gerados pelos efluentes de piscicultura desenvolvida no município de Macapá, Amapá. Foram feitas análises da qualidade da água em dois viveiros, através do monitoramento mensal das variáveis físico-químicas e biológicas no período de janeiro a outubro de 2012. As variáveis analisadas foram oxigênio dissolvido, pH, condutividade elétrica, transparência, turbidez, cor aparente, sólidos totais dissolvidos, cloretos, dureza total, ferro total, temperatura da água, temperatura do ar e clorofila-a. Para a comparação das médias dos resultados das variáveis físico-químicas e biológica (clorofila-a) dos viveiros, aplicou-se o teste t de Student. Também se buscou compara os resultados do estudo com os limites determinados pelas Resoluções ...

O objetivo do presente estudo foi descrever o perfil socioeconômico e o conhecimento sobre a legislação de pesca esportiva de pilotos-guia da Bacia do Médio Rio Negro, Amazonas. Foram realizadas entrevistas semiestruturadas, utilizando questionários com orientadores (N= 55), no período de janeiro de 2016 a maio de 2019. A média de idade dos orientadores foi de 42 anos, com faixa etária de 40 a 50 anos (39,59%), casados, com ensino fundamental incompleto (40,00%). A principal forma de contrato de serviço foi por temporada (56,00%). Cerca de 56,36% dos guias informaram que não tinham conhecimento da legislação vigente sobre pesca esportiva, a maioria deles nunca havia testemunhado nenhuma abordagem de supervisão (61,82%) pelas autoridades. Para a maioria, a pesca esportiva é uma atividade que causa impactos (49,09%), principalmente para peixes, resultando em lesõe...

O objetivo do presente estudo é realizar uma análise do perfil socioeconômico e do conhecimento tradicional sobre as arraias de água doce em relatos de pescadores no município de Barcelos, Amazonas. Foram entrevistados 54 pescadores que foram afetados por acidentes com arraias. Observou-se que 89,0% são do sexo masculino, demonstrando a manutenção das atividades de pesca que são passadas pelas famílias de crianças e jovens. A proporção de casos ocorreu com pescador com mais de 50 anos (62,2%). Há uma predominância do uso de puçá e rapiché que é um tipo de pesca ativa na qual não causa nenhum dano aos animais. Um total de 2,0% não identificou as cinco espécies presentes no rio Negro. Entre os sintomas apontados pelos pescadores após o acidente, foram citados dor, edema e, algumas vezes, necrose. É possível auxiliar os pescadores de águas doce sobre como se sucede...

Oryza spp, or Wild rice as it is commonly known, is native to the floodplains of muddy rivers in the Amazon region. The aim of this study was to analyze the physical performance and the effects of dietary levels of Oryza spp. via the hematological parameters, total food intake, conversion efficiency, growth ratio and swimming performance of this fish. Diets containing 45% Oryza spp. induced the best performance in tambaqui. Diets containing 15% and 30% did not affect these indices, thus indicating that this amount of Oryza can be used as an alternative energy source for this important species within Brazilian aquaculture.

The aims of present study was investigate the ecophysiological interactions and the relationship to the physical parameters of the water. In order to compare and ecologically correlate the species of peacock bass (Cichla monoculus, Cichla temensis and Cichla vazzoleri) in Lake Balbina, Presidente Figueiredo. The total of 45 animals, 15 individuals of each species, was captured with rod and reel, hand line with natural and artificial bait. The animals blood was removed by means of caudal puncture and the hematological data were determined according to methodology previously described in the literature. The analysis of water physical properties was determined during the collections. The Principal Component Analysis (PCA) was used for observations of interactions (60.00%). The PCA of the erythrogram showed an interaction of 86.26%, the ...

A total of 45 specimens were captured in Balbina lake, Presidente Figueiredo, Amazonas, Brazil, with the aid of a rod and reel or hand line, with natural or artificial bait: 15 C. monoculus, 15 C. temensis and 15 C. vazzoleri. Their blood was removed by means of caudal puncture of the dorsal aorta, and hematological data were determined in accordance with methodology previously described in the literature. The erythrogram showed similarities between the species, while the thrombogram showed differences between C. vazzoleri and the other species studied (C. monoculus and C. temensis). The total leukocyte counts for C. temensis and C. vazzoleri were higher than those of C. monoculus. The predominant leukocyte in C. temensis and C. vazzoleri was lymphocytes, ...

This area has fundamental importance for the populations from the Amazon. The present study aimed to describe socioeconomic profile of ornamental fishermen known as “piabeiros” in the Municipality of Barcelos, as well as the ornamental fishery, fisheries area, target species, environments, fishing techniques, equipment, capture techniques and main difficulties faced by the current activity. This study was carried out in municipality of Barcelos, through semi - structured interviews, with artisanal ornamental fishermen (N= 89). The main families of ornamental fish caught and traded were: Characidae, Lebiasinidae, Gasteropelecidae, Cichilidae, Anostomidae, Loricaridae, Potamotrygonidae and Gymnotidae. The main catchment areas were igarapés, lakes, flooded fields, beaches, river banks and igapó forest. Rapiché was the most used equipment in the fisheries both by the fishermen of the urban a...
