Production and Parasitological Characteristics of Invasive Short-Cycle Fish Species in Water Bodies on the Eastern Slope of the Southern Urals

摘要

In the course of planned or accidental fish intro-duction, rapid dispersal and range expansion are char-acteristic primarily of short-cycle species, i.e., small,early maturing fishes with partial spawning. A special place in the problem of population outbreaks and invasions belongs to the role of invasive species in the trophic structure of new biocenoses and also their role as carriers of some symbionts and parasites (Dge-baudze, 2002).
