c. imprinting  

Explanation:

Imprinting is the object of study of ethology, which is related to animal behavior. In the early stage of an animal's life, imprinting is an essential and most conducive phase for learning and subsequent development. The two main types of imprinting are sexual and filial.  In sexual imprinting, a young animal learns the traits it seeks in a mate. Affiliate imprinting is the learning of a offspring from his / her parent.

In the case of the salmon fish situation, the need for workers to raise fingerlings (salmon) in stream water during a certain critical period in their early development is an example of imprinting. In this case, imprinting is necessary for the development of this animal in a different environment from the one it was raised.
