    • The present invention relates to methods of imprinting fish in freshwater with at least one odorant for the fish and causing the imprinted fish to react to the odorant in seawater, wherein the fish are maintained in freshwater prior to transfer to seawater, The method includes: adding at least one Polyvalent Cation Sensing Receptor (PVCR) modulator to the freshwater in an amount sufficient to modulate expression and/or sensitivity of at least one PVCR, the PVCR modulator being one which alters olfactory sensing of the fish to the odorant; adding feed for fish consumption to the freshwater, the feed containing the odorant and an amount of NaCl sufficient to contribute to a significantly increased level of the PVCR modulator in serum of the fish upon consumption of the feed, whereby the fish are imprinted with the odorant; transferring the imprinted fish to seawater; and providing a source of said odorant in the seawater to which the imprinted fish are transferred, thereby causing the imprinted fish to react to said odorant. The present invention also includes methods of homing or attracting fish, as well as methods for repelling fish by modulating the expression and/or sensitivity of the PVCR in the olfactory apparatus of the fish.
    • 本发明涉及将淡水中的鱼印在鱼上的至少一种气味剂,并使印迹鱼与海水中的加味剂反应的方法,其中鱼在转移到海水之前保持在淡水中。该方法包括:加入 至少一种多价阳离子感应受体(PVCR)调节剂,其量足以调节至少一个PVCR的表达和/或敏感性,PVCR调节剂是将鱼的嗅觉感测改变为加臭剂的PVCR调节剂; 向淡水添加饲料,含有气味剂的饲料和一定量的NaCl足以有助于在饲料消耗时鱼血清中PVCR调节剂的水平显着提高,由此将鱼加上加味剂 ; 将印迹鱼转移到海水中; 并在所述海水中提供所述加臭剂的来源,所述海水中转印有所述印迹鱼,从而使所述印迹鱼与所述加臭剂反应。 本发明还包括归巢或吸引鱼的方法,以及通过调节鱼的嗅觉装置中PVCR的表达和/或敏感性来排斥鱼的方法。
