Fish detect extremely low levels of marine toxins tetrodotoxin (TTX) and saxitoxin (STX) via the specialized gustatory receptor(s). Physiological and pharmacological studies show that receptor(s) for TTX and STX are distinct from those which detect f

Fish sensory systems have been extensively studied not only because of a wide general interest in the behavioral and sensory physiology of this group, but also because fishes are well suited as biological models for studies of sensory systems. Fish P

Electro-olfactogram recording was used to determine whether the olfactory epithelium of adult rainbow trout is specifically sensitive to bile acids, some of which have been hypothesized to function as pheromones. Of 38 bile acids that had been pre-sc

Olfaction conveys critical environmental information to fishes, enabling activities such as mating, locating food, discriminating kin, avoiding predators and homing. All of these behaviors can be impaired or lost as a result of exposure to toxic cont

Bile acids have been implicated as chemical signals in spawning behaviour of lake char (Salvelinus namaycush). In this study, we investigated olfactory responses of lake char to bile acids by using the electro-olfactogram recording. Lake char detecte

The present study investigated behavioural responses of naive rainbow trout Oncorhynchus mykiss, lake charr Salvelinus namaycush, lake whitefish Coregonus clupeaformis and goldfish Carassius auratus to food extracts as well as selected amino acids (a

Behavioural and electro-olfactogram (EOG) responses to synthetic F-prostaglandins (PGFs) were recorded in the three salmonids: brown trout Salmo trutta, lake whitefish Coregonus clupeaformis and rainbows trout Oncorhynchus mykiss. Exposure to 10 -8 M

Actively spawning male Arctic char, Salvelinus alpinus , release immunoreactive F-prostaglandins into the water that attract ovulated females and elicit spawning behaviour. To investigate a possible role played by the olfactory system, we determined

To determine the functional variability of the gustatory system in salmonids, we examined electrical responses of the palatine nerve to amino acids in nine strains of rainbow trout (Oncorhynchus mykiss), four additional Oncorhynchus species, and two
