Аннотация: This study aimed to evaluate the effect of silver nanoparticles (AgNPs) on taste feeding behaviour including taste palatability index, fishing efficiency, and the number of consumed pellets to some selected amino acids in juvenile Persiansturgeon (A. persicus). Taste Feeding behaviour was investigated in the following exposure concentrations: 0.01, 0.005, and 0.001 mg L-1 AgNPs for 21 days (each group with three replicates and each replicate with seven fish). Then, the feeding behaviour of fish was investigated using experimental pellets containing 0.3% chromium oxide, 2% agar, and some selected amino acids (serine, arginine, cysteine, tyrosine, glutamic acid, and aspartic acid). The results showed that the taste palatability index was negative for all amino acids and pellets containing the chironomidae larvae extract in two concentrations of 0.01 and 0.005 mg L-1 AgNPs. Also, the number of consumed pellets was significantly lower than the control for all amino acids. Furthermore, AgNPs at all concentrations significantly reduced the fishing efficiency in some amino acids including arginine, cysteine, and tyrosine. Considering that the even the lowest concentration of AgNPs (0.001 mg L-1) had negative impact on taste feeding behaviour of Persian sturgeon. Therefore, it is recommended to keep the concentration of AgNPs at the minimum level (less than 0.001 mg L-1) before releasing to the aquatic ecosystems.
