..., contrasting with previous results and predictions regarding the adaptive benefit of these structures. Comparisons with a less venomous catfish species ( Ameiurus natalis ) indicate that a single protein present in the venom of N. gyrinus may be responsible for providing the significant selective advantage...

..., the maintenance of sensory functions in a changing environment may be crucial for an animal's survival. Many fish species rely on hearing for acoustic orientation and communication. In order to investigate the influence of temperature on the auditory system, channel catfish Ictalurus punctatus was chosen...

...S. H. Rolen; J. Caprio SUMMARY 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...

... and degree of pH recovery during hypercapnia. Waters of the Amazon are characteristically dilute in ions, which may have consequences for acid-base regulation during environmental hypercapnia in endemic fishes. The armoured catfish Liposarcus pardalis , from the Amazon, was exposed to a water P CO 2 of 7, 14...
