“…shallow and deep zones, tidal channels and tidal flats). Among other aspects, the limited use of sample artifacts, especially towed passive network (gillnets) on the American continent, are responsible for poor knowledge about the habitat use by estuarine fish fauna (Faunce & Serafy 2006).

“…Studies of faunal surveys constitute the initial step for biological studies and management of an area, by providing basic information on the composition and structure of the investigated fauna (Casatti et al 2001). However, the fact of the Todos os Santos Bay being the second largest semi-enclosed bay in Brazil and have no ichthyofaunal study in their estuaries (Andrade-Tubino et al 2008), besides the fact that studies reported for Brazilian estuaries are credited only to the north and south region (Faunce & Serafy 2006) sets up such a worrying scenario. The urgent need to know the ichthyofauna of the place so as to develop conservation and management measures corroborates the lack of these studies in estuarine environments.…”

Estuaries are areas of recognized importance in the development and sanctuaries of fishes and also a great source of fishing resources. This article presents an inventory of fishes from the Paraguaçu River estuary, Todos os Santos Bay, Bahia, Brazil. 28 points comprising the saline sections that may exist in a tropical estuary were sampled quarterly from March 2009 to February 2010 with the aid of bottom gill nets, surface gill nets, seine net and casting net. A total of 4.097 individuals were captured, belonging to 7 species of Chondrichthyes and 117 species of Actinopterygii (83 genera and 49 families). Most of the geographical extent of the estuary was sampled by assessing large spatial variability in fish assemblage structure. The curve of species accumulation (rarefaction) had stabilization with ½ of the samples. The general structure of the assemblage is described and commented trough evidences for a new spatial organization of the fish fauna due to dam effects upstream the estuary. Resumo: Estuários são áreas de reconhecida importância no desenvolvimento e refúgio dos peixes e também grande fonte de recursos pesqueiros. Este artigo apresenta um inventário dos peixes do estuário do Rio Paraguaçu, Baía de Todos os Santos, Bahia, Brasil. 28 pontos constituindo as três seções salinas que pode haver em um estuário tropical foram amostradas trimestralmente de março de 2009 a fevereiro de 2010 com auxílio de redes de espera de fundo, de superfície, redes de arrasto manual e tarrafas. Um total de 4.097 indivíduos foram capturados, pertencendo a 7 espécies de Chondrichthyes e 117 espécies de Actinopterygii (83 gêneros e 49 famílias). A maioria da extensão territorial do estuário foi amostrada para acessar maior variabilidade espacial na estrutura da assembléia de peixes. A curva de acumulação de espécies (rarefação) apresentou estabilização com ½ das amostras. A estrutura geral da assembléia é descrita e comentada através de evidências para uma nova organização espacial da fauna de peixes devido a efeitos de barragem a montante do estuário.

Biota Neotrop., vol. 10, no. 4 Keywords: inventory, estuarine fishes, spatial distribution, effects upstream, brazilian northeast. REIS-FILHO Material and MethodsFishes were collected at 28 points within the Paraguaçu River estuary with quarterly samples between March 2009 and February 2010 (Figure 1). Several types of collectors were used: for marginal environments and with depths up to 3 m, trawl manual (12 m × 2 m with 12 mm mesh), gillnets (100 m × 3 m with 15 mm mesh) and flue (casting net ) (10 mm mesh). For environments with depth between 4 and 20 m, bottom gill nets (300 m × 3 m with 20 mm, 30 mm, 40 mm, 50 mm and 60 mm mesh) and surface gill nets (200 m × 4 m with 15 mm mesh) were used. In order to evaluate the ichthyofauna distribution in the estuary, this one was segmented into three sections (lower, middle and upper).

“…Mangroves and other shallow-water tropical habitats are believed to function as nursery habitats for reef fish, sheltering large numbers of juvenile fish among the prop roots to a varying degree (Parrish 1989;Nagelkerken et al 2000Nagelkerken et al , 2002Faunce and Serafy 2006). The presence of mangroves increases abundance or biomass and enhances fish communities on nearby reefs and fisheries (Dorenbosch et al 2004(Dorenbosch et al , 2005Mumby et al 2004;Manson et al 2005).…”

The Impact of Mangrove Prop-Root Epibionts on Juvenile Reef Fishes: A Field Experiment Using Artificial Roots and Epifauna

A field experiment was established in Bocas Del Tom, Panama to examine the relationship between sessile organisms living on mangrove prop roots and fish communities. Artificial mangrove roots (AMR) with different sets of artificial (AE) or real epibionts were established in five different locations in two separate years. Fish species in each plot were identified, counted, and their size estimated by visual census for 15 days in each replicate. In the artificial mangrove plots, the treatments with the most heterogeneous structure had significantly greater abundance of most families and species richness of fish in both years of the experiment. AMR plots with AEs attracted a more abundant and diverse fish assemblage than those with live epibionts, which had lower three-dimensional structure. All of the AMR plots had significantly greater fish abundance than comparable plots of sea grass alone. The location of the replicate also made a significant difference to fish abundance. The data indicate that prop-root epibionts can enhance fish abundance and diversity in mangroves,

“…Tropical estuaries are characterized by the presence of mangrove environments (Faunce & Serafy, 2006;Nagelkerken et al, 2008) that have high structural complexity, serving as substrates for algae development and diatom colonization (Hindell & Jenkins, 2004); therefore, tropical estuaries have high resource availability (Wang et al, 2009). Estuarine environments play an especially important role as nurseries, as they have characteristics that are advantageous for young individuals, such as high temperatures, high prey availability, and refuge from predators, which may increase growth rates and survival (Beck et al, 2001;Potter et al, 2015).…”

ABSTRACT. The present work aims to characterize a fish assemblage from a northeastern Brazilian estuary according to its diet and trophic organization along the estuarine-reef gradient. Sampling was performed at the Mamanguape Estuary, and fishes were collected using three types of nets at seventeen sites, grouped into four regions according to salinity range: reefs and the lower, middle, and upper estuary. The most abundant species were Atherinella brasiliensis, Mugil curema, and Sphoeroides testudineus. The highest species abundance and richness was observed for the lower estuary. Zooplankton was the most consumed category, recorded for fortytwo species. Among the guilds, piscivores were the most abundant, followed by crab eaters. Herbivores, mostly represented by Abudefduf saxatilis, had a higher abundance in reefs, being correlated according to ANOSIM analysis to this region, while piscivores and crab eaters showed a high contribution to inner regions of the Mamanguape Estuary.
