Active Outcome of Pink Salmon Oncorhynchus gorbuscha (Salmonidae) Fry into the Water Current for Passive Downstream Migration

详细

Field experiments and observations revealed that active outcome of pink salmon fry Oncorhynchus gorbuscha into the riverine water current precedes its passive downstream migration. Inherited behavioral reactions (rheoreaction, optomotor reaction, photo- and tigmoreactions) in response to environmental changes determine the outcome.
