The density of fish aggrega acteristic primarily of shortcycle species, i.e., small, early maturing fishes with partial spawning. A special tion was estimated by the area method (Lapitskii, place in the problem of population outbreaks and 1970) or using hydroacoustic instruments and control catches (Truskanov and Shcherbino, 1966; Permitin invasions belongs to the role of invasive species in the and Polovkov, 1979).
