Physiology of Fish in Intensive Culture Systems

This reference offers practical and technical information on the chemical, physical and biological effects of intensive rearing conditions of hatchery fish, and the adverse affect these factors can have on their health and physical condition. A combination of theory and practical applications is presented throughout the book, providing the scientific basis for managing water quality, fish cultural procedures, and the biological interactions of the fish being produced to prevent diseases and costly production losses. The book begins with a discussion of the physiological functioning of fish under normal conditions. It then explains the interactions between fish and the chemical factors in the rearing environment, including the effects of the algal toxins that currently cause serious economic losses in freshwater and marine aquaculture operations world-wide. The next chapter covers the physiological effects of common fish cultural procedures with emphasis on development of anadromous salmonids.
