1. Marine organisms reared in tanks, especially larval fish, are almost certainly deprived of sufficient sensory input for the proper development of the sense organs and their associated areas in the central nervous system. Input is also inadequate for the development of learned behavioural and physiological responses.

2. Input of a deleterious kind, as a result of social stress in crowded conditions, may also be present, leading to abnormal behaviour and undesirable morphological consequences. Specific inhibitors may also retard the growth of smaller individuals.
