Electric Fishing

Our study analyzes the distribution of fish communities related to the environmental variables of the Alto Madre de Dios River, an Andean-Amazon watershed of southern Peru, between 300 and 2811 m a.s.l. within the Manu Biosphere Reserve. We provide new ecological and diversity data on fishes for these poorly studied rivers and new data for palm swamp habitats. With electric fishing techniques, we collected a total of 1934 fish specimens belonging to 78 species, 42 genera and 15 families. To assess main patterns of diversity we combined SIMPER and ANOSIM with canonical correspondence analysis to obtain an overview of the community structure of fish and their distribution related to aquatic habitats. Our results show an important shift on fish diversity at 700 m a.s.l. separating headwater and middle-lowland communities. Electrofishing was a hindrance due to the depth, flow and low conductivity of the rivers, but also allowed us to capture fish not observed with other techniques. We also compared the use of elevation with slope as an alternative variable for statistical analysis. Our results show that slope offers a solid and equivalent explanation for fish distribution variability, avoids redundance, and instead of giving geographical data offers ecologically solid information.

Distribution Of Fish

The spatial distribution of yellow perch (Perca flavescens), white sucker (Catostomus commersoni), smelt (Osmerus mordax), chub spp. (Coregonus spp.) and alewife (Alosa pseudoharengus) caught in gill nets fished in South Bay of Lake Huron is described. The vertical distribution was essentially the same for all catches examined, the fish being concentrated towards the bottom of the net. The lateral distribution varied with species, mesh size and setting. Three types of lateral distribution were recognized, namely random, dispersed and bunched. Possible reasons for these different types and the relation between the distribution of fish in the net and in the water are discussed.

O presente estudo teve como objetivos identificar e caracterizar os principais fatores fisiográficos das áreas estuarinas em Pernambuco, assim como as ações antrópicas por elas sofridas; listar os peixes que vivem nesses estuários, atualizando as validações dos nomes científicos das espécies; e analisar a distribuição dos registros de ocorrência das espécies por estuário. Os dados para a análise dos estuários foram baseados em três trabalhos sobre áreas estuarinas em Pernambuco. As informações sobre a ictiofauna foram obtidas a partir de 25 monografias, dissertações, teses, livros e artigos científicos. Foram utilizadas imagens das áreas estuarinas obtidas através do aplicativo Google earth. Foram identificados 17 estuários em Pernambuco, onde a ictiofauna é pouco estudada. As maiores concentrações das pesquisas ocorreram no complexo estuarino de Itamaracá e no estuário do rio Formoso, porém para algumas áreas não existem informações sobre comunidade de peixes. Foram listadas 202 espécies de peixes válidas, sendo 52,5% delas associadas a recifes. Quanto à freqüência de ocorrência, Citharichthys spilopterus e Poecilia vivipara foram classificadas como muito freqüentes, enquanto Carangidae, Gerreidae, Ariidae e Haemulidae foram as famílias mais especiosas. Atualmente, as áreas estuarinas estão em acelerado processo de degradação devido aos aterros, despejos de esgotos domésticos e industriais, desenvolvimento urbano, viveiros de carcinicultura e construção/ampliação de portos em prol do crescimento econômico. Diante desse contexto, torna-se necessário que os órgãos de fomento à pesquisa em Pernambuco estimulem estudos nessas áreas para possibilitar uma pesca sustentável. Palavras-chave: Comunidade de peixes, áreas estuarinas, impactos ambientais.
