Similar to bony fish, feeding preference in Larimichythys crocea is determined by the smell and taste of food which is mainly controlled by the olfactory system. Ten different L-types of amino acids at different concentration levels were introduced to the large yellow croaker and significant differences in the olfactory response with reference to odor detection were observed. Movement and feeding responds were taken within a 4-minutes interval which showed an increase in the responsiveness of the fish with increase in the concentration of specific amino acid from 0.01 M/L to 0.08 M/L. There was a significant difference between different kinds of amino acid with high responses from L-Arginine and L- Tryptophan. The olfactory epithelium before and after administering L-amino acid was observed and it showed remarkable differences with the top of the cilia being inflated in the a.. View More»
