Bile salts are known olfactory stimuli for teleosts, but only a single report has indicated that the taste system of a fish was sensitive to this class of stimuli. Here, gustatory responses of the channel catfish, Ictalurus punctatus, to four bile salts that included taurine-, glycine- and non-conjugated compounds along with three stimulatory amino acids as a comparison were investigated using ...

The number of goatfish species has increased recently, thanks in part to the application of molecular approaches to the taxonomy of a family with conservative morphology and widespread intraspecific color variation. A new subspecies Mulloidichthys flavolineatus flavicaudus Fernandez-Silva & Randall is described from the Red Sea and Arabian Sea, including Socotra and Gulf of Oman. It is characte...

Sex identification is linked to sexual dimorphism and an important study issue in fish biology aquaculture. However, owing the unmarked heteromorphism between adult Hemibarbus labeo, it often difficult distinguish their sex by visual observation. This aimed find a simple reliable morphometric criterion for of H. labeo using discriminant models. Forty-two traits sixty-eight individuals collected...

introduction the pollution of the aquatic environment with heavy metals and trace elements has become a worldwide problem during recent years, because they are indestructible and most of them have toxic effects on organisms. potentially toxic elements (ptes) added to an aquatic system by anthropogenic and natural sources are distributed during their transport between different compartments of a...

This study evaluated the population biology of Ctenosciaena gracilicirrhus (Perciformes: Sciaenidae) in a shallow non-estuarine coastal area of southeastern Brazil. Monthly samples were taken from October 2003 through October 2004, in two distinct areas at depths from 1 to 4 m. C. gracilicirrhus was generally among the most abundant fish species during the period. Its density was significantly ...
