For the first time in ichthyological literature, the author has analyzed the structure of fish populations in inland reservoirs based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes, and seven from large reservoirs in plains. Special attention has been paid to the main indicator of the structure of population - correlation between the age of ichthyomass culmination and mass maturation. Data have been presented on age-related changes of ichthyomass in many generations of 11 species of c...
For the first time in ichthyological literature, the author has analyzed the structure of fish populations in inland reservoirs based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes, and seven from large reservoirs in plains. Special attention has been paid to the main indicator of the structure of population - correlation between the age of ichthyomass culmination and mass maturation. Data have been presented on age-related changes of ichthyomass in many generations of 11 species of commercially important fish. It is shown that populations of the investigated species of fish attain their maximum ichthyomass before reaching mass maturation or both these events are concurrent. Three types of population structure have been identified and their characteristics presented. The material presented in the book and conclusions derived are of great interest both for developments in population ecology of fish and the theory of optimal fishing. The book is intended for ichthyologists, hydrobiologists, and ecologists studying theoretical bases of fish ecology and tackling applied questions of regulated fishing and conservation of fish stocks.
