| Abstract | Though relatively high concentrations of taurine are found in the olfactory bulb, the part of the brain that receives messages from the olfactory epithelium, few studies have explored the role that taurine plays in olfactory function, which is important for triggering feeding behavior, food consumption, and ultimately growth. A behavioral experiment was conducted to measure the response of juvenile sablefish to a food odor to determine whether there was a difference between fish fed a low taurine, plant-based diet versus those fed an otherwise identical diet supplemented with 1% taurine. Fish fed the taurine-supplemented feed (1 TAU) had a significantly higher whole-body taurine concentration, 0.208 ± 0.029% than fish fed the unsupplemented feed (0 TAU), 0.069 ± 0.010%, p<0.0001, and the initiation of a search response by the introduction of a food odor was stronger in fish fed the taurine supplemented diet, 0 TAU n=58, 1 TAU n=59, p=0.001. Taurine levels in feed should be of concern t |
