Condition and Health Indicators of Exploited Marine Fishes/Оценка состояния и здоровья промысловых морских рыб

Издание на английском языке
This publication is devoted to fish health indicators and their use in biology, ecology, and fisheries resource management. The book examines morphometric, physiological, and biochemical indicators reflecting fish nutrition, metabolism, growth, reproduction, and life cycle. The influence of the environment, climate, pollution, fisheries, and aquaculture is discussed separately, as well as the application of these data to assessing habitats, populations, and commercial stocks.
