“…Other studies also found similar patterns (Vendel et al, 2002;Robertson & Duke, 1990). The spring spawning of B. ronchus in the mangrove channels of the Baía de Guaratuba has been reported by Chaves (1995). A. parva leaves the interior of the estuaries to spawn during the spring (Esper, 1982), but several mature individuals were captured in the tidal creeks.…”

Tidal creeks are meandering channels that are highly influenced by tidal changes and can experience substantial variation in salinity and depth over the course of the same day. The goal of the present work is to survey the ichthyofauna associated with these environments and to assess seasonal differences in their composition in tidal creeks of the euhaline sector of the estuary of the Paranaguá. Two tidal creeks of the Pinheiros bay were sampled monthly at the same time using fyke nets. A total of 13,755 fish from 55 species and 27 families were captured. Only the clupeiforms Anchoa parva, Cetengraulis edentulus, and Harengula clupeola showed substantial seasonal variation in abundance, being most frequent during the fall and its adjacent months. Benthophagic individuals such as Sphoeroides testudineus, Bairdiella ronchus and Cathorops spixii were the most dominant in terms of biomass and were present all year long, although with irregular abundance. Sciaenid species were most frequent in the fall and winter, both as juveniles and as adults. The spring and part of the fall were characterized by the highest number of species with mature gonads, whereas the fall was the most important recruitment period, causing an increase in the richness indices and in the number of captured individuals. Tidal creeks were intensively visited by fish of all trophic levels and ages. These results, together with the high richness and diversity indices, corroborate the importance of tidal creeks for the preservation of estuarine environments.

“…An explanation for this pattern is that the tide channel was dominated by the resident estuarine species A. parva, B. ronchus, G. genidens, S. greeleyi, and S. testudineus and the marine species H. clupeola, with similar life histories. The resident ones spawned at the site or close to the area in the spring and summer, and the marine species in the adjacent coastal zone (Chaves, 1989(Chaves, , 1995Rocha et al, 2002;Schultz et al, 2002), with the recruitment occurring mainly between the summer and beginning of winter. Reproduction in the spring and summer, with subsequent recruitment in the summer and autumn has been observed in most of the local species (Pinheiro, 1999;Chaves & Otto, 1999;.…”

The fish assemblage in a mangrove tidal creek was studied in monthly collections between August 1998 and July 1999 in the quadrature low tide and high tide, using a fyke net of 30 m x 1.5 m and meshes of 8 and 10 mm. Simultaneously with the biological collections, temperature, salinity, pH, water transparency, and current speed data were obtained. The collections resulted in the capture of 36,873 fish representing 22 families and 52 species. Immature individuals abounded (63.8%), and among the adult specimens there was a larger number of females. The species Anchoa parva, Harengula clupeola, Genidens genidens, and Bairdiella ronchus, contributed to 84.9% of the total capture of fish, however the contribution in mass was of 55.2%, indicating a predominance of small individuals. A smaller number of fish and species seem to occupy the area in the period between August and December, in comparison to the period between February and July, when the larger aggregations appear, mainly of the species Anchoa parva, Harengula clupeola, Opisthonema oglinum, Genidens genidens, Diapterus rhombeus, and Bairdiella ronchus. The environmental factors, pH, water transparency, and rainfall seem to have an influence in the structure of the observed biological patterns.Key words: tidal creek, fishes, diversity, abundance, temporal variation. RESUMO Um estudo sobre a estrutura da comunidade de peixes de um rio de maréA comunidade de peixes em um rio de maré de mangue foi estudada em coletas mensais entre agosto de 1998 e julho de 1999 na baixa-mar e preamar de quadratura, utilizando-se uma rede fixa tipo "fyke" com 30 m x 1,5 m e malhas de 8 e 10 mm. Simultaneamente às coletas biológicas, foram registrados dados de temperatura, salinidade, pH, transparência da água e velocidade da corrente. As coletas resultaram na captura de 36.873 peixes, representando 22 famílias e 52 espécies. Predominaram indivíduos imaturos (63,8%) e as fêmeas, entre os adultos. As espécies Anchoa parva, Harengula clupeola, Genidens genidens e Bairdiella ronchus constituíram 84,9% da captura total de peixes, no entanto, a participação em peso foi de 55,2%, indicando o predomínio de indivíduos de pequeno porte. Um menor número de peixes e espécies parece ocupar a área no período entre agosto e dezembro, comparado ao período entre fevereiro e julho, quando aparecem os maiores agregados, principalmente das espécies Anchoa parva, Harengula clupeola, Opisthonema oglinum, Genidens genidens, Diapterus rhombeus e Bairdiella ronchus. O pH, a transparência da água e a pluviosidade parecem influenciar a estruturação dos padrões biológicos observados.Palavras-chave: rios de maré, peixes, diversidade, abundância, variabilidade temporal.

“…Johnson (1978) cita o uso de áreas estuarinas com fundos lodosos por juvenis e adultos desse gênero, sendo que a desova da espécie pode ocorrer nestes ecossistemas (Johnson, 1978;Chaves, 1995). I. parvipinnis, M. atricauda, L. breviceps e P. cromis tiveram baixa abundância durante todo o período de estudo, utilizando a baía da Babitonga de forma ocasional.…”

16%) and Stellifer spp. (17,6%) being the most abundant taxa. Fish larvae showed the highest densities during Spring and Summer months, and occupied the whole estuary. Temperature and salinity were the main factors structuring the distribution of Sciaenidae larvae. Preflexion stage was the most abundant, but vitelline, flexion and postflexion larvae were also reported. The presence of different early life stages of Sciaenidae in Babitonga Bay reveals the important role of this ecosystem as a nursery for target species of South-Southeast Brazil fisheries.
