“…Species were classified according to the trophic levels determined by Bouchon-Navaro et al (1992), which place fish into the following categories: planktivores (P) -food is composed mainly of plankton; omnivores (O) -species that feed on invertebrates and at least 10% of algae; herbivores (H) -from algae to seagrass; first order carnivores (IC) -small benthic invertebrates; second order carnivores (IIC) -invertebrates and fish; third order carnivores (IIIC) -fish makes up 80% of the food ingested. The species that were not evaluated by Bouchon-Navaro et al (1992) and Paiva et al (2009) were classified based on their food items, as available in the following website: www. fishbase.org.…”

“…For the demersal fishes that inhabit sandy beaches, lighting variation between day and night periods and tidal cycles represent a determinant factor in their behavior, especially for individuals that live in shallow waters (Rountre & Able, 1993;Paiva et al, 2009). Moreover, the incident light exerts influence on the abundance of many species, changing in the composition and richness of fish assemblages (Clark et al, 1996).…”

“…Outra limitação que deve ser prontamente reconhecida diz respeito à visibilidade. As águas estuarinas são notórias por sua alta produtividade e grande quantidade de material em suspensão (Odum 1988 Paiva et al (2008Paiva et al ( , 2009. Propomos que esta diferença na frequência relativa encontrada entre o presente trabalho e os trabalhos citados pode estar relacionada a metodologia utilizada, o que demonstra a importância de amostragens com utilização de observação subaquáticas em ambientes estuarinos.…”

Abstract:The mangrove vegetation along the margins of estuaries is an important habitat for fish, serving as feeding, shelter and nursery zones. The present work describes the fish fauna associated to mangrove roots at the Pacoti River estuary. A total of ten visual censuses of 90 minutes each were conducted, yielding the number of 671 fish counted, with an average of 0.74 counts/minute. The fishes were identified pertaining to 22 species from 18 different families. All the studied species are originally marine, although the samples were mainly carried out during the rainy season. Gerreidae and Lutjanidae were the more representative families. The species Lutjanus alexandrei, Lutjanus jocu and Bathygobius soporator were present in all censuses and the first two were also the most abundant, with 48 and 17% of the total counts, respectively. Taking into account size estimations of the fish, it was verified that mangrove roots are inhabited mainly by juveniles of both species, indicating the use of this habitat as a nursery area. However, in the least complex sampling site, specimens of genus Lutjanus were sought in higher quantities, comprinsing all size classes, thus suggesting the abundance of roots in Pacoti River might not influence the abundance of sheltered fishes. Another important observation is that almost 70% of the species present in the mangrove roots are typical of reef habitats, indicating the existence of strong connections between these two ecosystems. The results emphasize the importance of this habitat for ichthyofauna conservation to coastal areas. In addition, studies regarding to fish recruitment, reproductive and trophic patterns are needed, especially to those two main important species described herein. Resumo: Margens de estuários com a vegetação de manguezal formam um importante hábitat para peixes, pois são zonas de alimentação, abrigo e berçário. O presente trabalho tem como objetivo caracterizar a ictiofauna associada às raízes de mangue do estuário do Rio Pacoti (CE). Foram realizados 10 censos visuais com duração de 90 minutos cada. Foram feitas 671 avistagens, com densidade média de 0,74 avistagens/minuto. Os indivíduos pertencem a 22 espécies e 18 famílias. Todas as espécies registradas são de origem marinha, apesar das amostragens serem realizadas principalmente no período chuvoso. As famílias que apresentaram um maior número de espécies foram Gerreidae e Lutjanidae. As espécies que apresentaram maior frequência de ocorrência foram Lutjanus alexandrei, Lutjanus jocu e Bathygobius soporator, estando presentes em todos os censos. As duas espécies mais abundantes foram L. alexandrei (48%) e L. jocu (17%). Levando-se em consideração as estimativas de tamanho destas espécies, foi verificado que as raízes de mangue são habitadas principalmente por indivíduos jovens de ambas as espécies, o que leva a supor que estas utilizam tal habitat como área de berçário. Contudo, na estação de coleta com menor complexidade estrutural foi avistado o maior número de indivíduos do gênero Lutjanus, em p...
