Mixed crustaceosis infestation at black-head minnows

Abstract

The purpose. To analyze peculiar features of diagnostics, seasonal prevalence and clinical attributes at black- head minnows at admixed crustaceosis infestations. Methods. Methods of clinical inspection and incomplete parasitologic opening. Results. Data concerning clinical attributes of parasitizing of agents of crustaceosis are obtained. It is determined that in summer flash of Lernaeosis Lernaea (at different stages of growth, except for puberal) can be located on gills of a fish. Conclusions. Simultaneous parasitizing on a fish of different agents of crustaceosis infestation can be observed more often in the spring-and-summer season. At admixed crustaceosis infestation the agent of Lernaeosis, in comparison with agents of arguleosis, sinergasileosis and ergasileosis prevails.
