Abstract:
1. A method of imprinting fish in water with at least one odorant for said fish and causing the imprinted fish to react to said odorant, said method comprises: a. adding at least one Polyvalent Cation Sensing Receptor (PVCR) modulator to the water in an amount sufficient to modulate expression and/or sensitivity of at least one PVCR, said PVCR modulator being one which alters olfactory sensing of the fish to the odorant; b. adding feed for fish consumption to the water, said feed containing said odorant and an agent sufficient to contribute to a significantly increased level of said PVCR modulator in serum of the fish upon consumption of the feed, whereby the fish are imprinted with the odorant; and c. providing a source of said odorant in the water in which the fish are maintained or transferred, thereby causing the imprinted fish to react to said odorant.
