ResumoEste estudo teve como objetivo descrever as variações espaço-temporais da ictiofauna em uma laguna costeira aberta. Os peixes foram coletados na Lagoa da Conceição, Florianópolis-SC, totalizando 19 meses de amostragem entre outubro de 1987 e novembro de 1989. Foram realizadas coletas em sete pontos, sendo que em cada um foram empregados lances de tarrafa de diferentes malhas, rede de mão do tipo puçá, rede de arrasto de praia e pesca manual com anzóis. Foram coletados 8.299 indivíduos, classiicados em 61 espécies pertencentes a 28 famílias de peixes, totalizando 52.902,4 g. Em relação à permanência na laguna, 48 espécies (80%) foram classiicadas como visitantes e as outras 12 eram residentes. Foram observadas diferenças signiicativas entre as estações (n, biomassa, riqueza de espécies e H'Loge), entre as áreas (n e riqueza de espécies) e nas interações entre os fatores estação e área (n e biomassa). Os dados sobre a ictiofauna reforçam a importância ecológica do ambiente da laguna costeira como área berçário e de alimentação, já que a maioria das espécies encontra-se em fases de recrutamento dentro da Lagoa da Conceição.

Abstract Are the ish distribution patterns in an open coastal lagoon in the subtropical west Atlantic inluenced by spatial and seasonal variations?This study aimed to describe the spatial-temporal variations of the ish fauna in an open coastal lagoon. Fish were collected in Lagoa da Conceição, Florianópolis, Santa Catarina, Brazil, totaling 19 sampling months between October 1987 and November 1989. Sampling took place at 7 sites, and in each of them cast net throws of different meshes, "puçá" handheld ishing net, beach seine ishing net, and manual ishing hooks were used. A total of 8,299 individuals were collected, classiied into 61 species belonging to 28 ish families, totaling 52,902.4 g. Regarding stay in the lagoon, 48 species (80%) were classiied as visitors and the other 12 were residents. Signiicant differences were observed between seasons (n, biomass, species richness, and H'Loge), between areas (n and species richness), and in the interactions between the factors season and area (n and biomass). Data on ish fauna reinforce the ecological signiicance of the coastal lagoon environment as a nursery and feeding area, since most species are at recruitment stages within Lagoa da Conceição.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
