TEMPERATURE AND IMMUNITY IN RAINBOW TROUT {ONCORHYNCHUS MYKISS)

摘要

Seasonality dominates the life history of fish. It affects a variety of factors including growth, reproduction and immune response. Environmental factors, mainly temperature and photoperiod, are known to undergo circadian and circumannual rhythms andhave been proposed to be direct causative agents of these variations. This work examines the effect of temperature on serum lysozyme activity, blood counts and general disease resistance at three treatment temperatures (5, 10 and 18°C) and then after acclimation to a challenge temperature of 15°C.
