Effects of Four Insecticides on the Ability of Atlantic Salmon Parr ( Salmo salar ) to Learn and Retain a Simple Conditioned Response
The learning ability of untreated, acetone-treated, and insecticide-treated Atlantic salmon parr was determined in a shuttlebox conditioning apparatus. Learning improvement on second conditioning was also tested.The results were that: (1), acetone did not affect learning; (2), with treatment for 24...
