Auditory sensitivity in the bullhead catfish (Ictalurus nebulosis).

Epizootiology of Channel Catfish Virus Disease

Channel catfish virus disease (CCVD) is a highly pathogenic herpesvirus disease of cultured channel catfish, Ictalurus punctatus, fry and fingerlings. The disease is confined to the southern United States, but occurs sporadically in other areas where young channel catfish are intensively cultured. Blue catfish, I. furcatus, have been experimentally infected with CCV, but other ictalurids appear...

The behavioral detection of binary mixtures of amino acids and their individual components by catfish.

The question of whether a binary mixture of amino acids is detected by fish as a unique odor or whether the qualities of the individual components are retained within the mixture was investigated in channel (Ictalurus punctatus) and brown bullhead (Ameiurus nebulosus) catfish, species that are highly similar in their olfactory receptor and behavioral responses to amino acid odorants. Catfish re...

Ontogenetic Development of Weberian Ossicles and Hearing Abilities in the African Bullhead Catfish

BACKGROUND The weberian apparatus of otophysine fishes facilitates sound transmission from the swimbladder to the inner ear to increase hearing sensitivity. It has been of great interest to biologists since the 19(th) century. No studies, however, are available on the development of the weberian ossicles and its effect on the development of hearing in catfishes. METHODOLOGY/PRINCIPAL FINDINGS...
