| Summary: | Heat shock proteins (Hsps) are robustly induced by diverse stressors that
denature proteins. In addition to stress resistance, Hsps are involved in the
folding of nascent proteins, plant and animal development, aging, environmental
adaptation and the immune response, demonstrating the fundamental
importance of these proteins to cell survival. Heat shock proteins are induced
in aquatic organisms by perturbations of temperature and salinity, environmental
contaminants, handling, hormones and biotic stressors. Exposure to
sublethal stress may enhance tolerance to a subsequent stress, a process termed
induced thermotolerance, and provide protection to stressors other than the
initial stress, known as cross-tolerance. In the present review, we briefly
describe the established approaches that are used to control disease during
aquaculture. This is followed by documentation of Hsp induction after exposure
to stressors commonly encountered by aquatic organisms. Induced
thermotolerance, cross-tolerance and immune enhancement by Hsps are also
considered. Although physiological stress is known to decrease disease resistance
it is now becoming clear that stress-induced Hsps enhance the tolerance
of aquatic organisms to disease. Potential applications for Hsps in the commercial
production of fish, crustaceans and molluscs are indicated, an issue of
significance when the importance of aquaculture in feeding the world’s population
is realized. |
