Abstract: This work was carried out from the assessment of conservation status freshwater ichthyofauna Bahia State. The inventory data and species distribution were obtained specialized scientific literature representative ichthyological collections. A total 281 native recorded in State, distributed Northeastern Mata Atlantica (NMA) São Francisco (SFR) ecoregions. There a larger number NMA (187 spp.), composed by several coastal basins, than SFR (134 river basin. Among 30 families recorded,...
Trophic plasticity is a distinctive feature of freshwater fishes, representing an essential strategy for fish living in resource-variable environments. We analyzed the stomach contents individuals sampled two Atlantic Forest streams to identify primary food sources consumed by Psalidodon aff. fasciatus and verify existence spatial, seasonal, ontogenetic variations. The diet was determined analyzing using Volume Method quantify importance items. In general, classified as omnivorous species,...
The coast of Bahia state is the longest along Brazilian coastline, and there are significant knowledge gaps concerning its estuarine fish fauna. Thus, a need to provide extensive coverage ichthyofauna an updated checklist fishes, which could function as database for management such biodiversity. Therefore, this study aimed characterize three different important systems (Camamu, Todos os Santos Bay, Caravelas) in contribute information on shallow areas state. We recorded 29 orders, 54...
Understand how environmental factors correlate with the trophic structure of fish communities is a fundamental step to allow designing models for functioning stream ecosystems and planning conservation actions. Thus, this study aims characterize streams Contas River basin evaluate relationships between local (stream limnological variables) structure. We sample nine Upper sub-basin Gongogi using electric fishing. analyzed diet 24 species, arranged in six guilds, according stomach contents:...
This study aims to evaluate the efficiency of electric fishing and seine-net/dip-net obtain quantitative qualitative data on fish community low conductivity streams in semi-arid region Bahia, Brazil. Samplings were collected 15 Chapada Diamantina. Two homogeneous stretches with 50 m each selected closed blocking nets. Zippin analysis was used suitability capture method. Differences abundance, richness, composition species, length specimens captured compared for Twenty-nine species collected,...
ABSTRACT Studies on the composition of fish diet and how species exploit food resources are especially relevant in tropical freshwater systems, where dietary plasticity is a commonly used strategy. In this study, we analysed spectrum environmental, seasonal ontogenetic variations characid [Hemigrammus marginatus Ellis, 1911 (Characidae)] region Upper Contas River, Diamantina Plateau, Brazil. We verified an omnivorous/invertivorous opportunistic habit, with predominance insects...
The present study investigates the diet composition and feeding strategy of Kalyptodoras bahiensis by verifying variations during hydrological cycle between males females. Samples were collected periods rain drought using various fishing gears adapted to each microhabitat. In laboratory, fishes weighed measured. An abdominal incision was made observe gonads for sex determination stomach removed identification quantification food items. importance item in calculated Feeding Index. Amundsen...
This work describes the length-weight relationship (LWR) of ten fish species from Contas River Basin, Bahia State, Brazil. Sampling was conducted quarterly between November 2012 and 2013 in 18 wadeable streams (nine Diamantina Plateau, Caatinga biome, nine Atlantic forest biome). The fishes were caught using electrofishing (800V DC) hand nets (2.0 mm mesh size) 50 meters stretch by sample unit. Collected fixed formalin preserved alcohol, thus some shrinking probably occurred. values...
This study reports the first record of Length-Weight Relationships (LWR) eight endemic freshwater fish species from Paraguaçu River basin, Northeast Brazil. Sampling was conducted in thirteen streams using electrofishing. Only Kalyptodoras bahiensis specimens middle section river were obtained local fishermen. Fishes fixed with 4% formalin before measurement, so some shrinking should be considered. Total weight (TW) measured to nearest 0.1 g and standard length (SL) cm. The LWR parameters...
O monitoramento da qualidade água é um dos principais instrumentos para o planejamento e gestão de recursos hídricos, seus resultados fornecem importante subsídios as ações controle ambiental. Este trabalho teve como objetivo avaliar variações sazonais temporal das condições físico-químicas biomassa fitoplanctônica (concentração clorofila a) do rio Jiquiriçá. A hipótese que rege este haverá variação parâmetros físicos, químicos biológicos Jiquiriçá entre os períodos pontos amostrais com...
