Role of stress in disease induction and methods to monitor stress on aquatic animals - Winter school on recent advances in diagnosis and management of diseases in mariculture, 7th to 27th November 2002, Course Manual

摘要

A fish's environment is a complex system with varying water quality,udtemperature, light intensity, current velocity, aquatic vegetation, food availability andudsocial interactions. The response of fishes to these changes assumes greater importanceudwith large scale culture offish. In case of cultured species, man's interference is a majorudfactor. Fishes are extensively and intensively reared in captivity, often submitted toudconfinement, handling, transportation and drug treatment. A valuable contribution fromudthe field of biological sciences would be the accumulation of information on theudphysiological response of fish to these environmental changes.
