Мonitoring of the Gimoly lake ecosystem, Republic of Karelia

Research results of the integrated assessment of the current state of the Gimoly Lake ecosystem, western Karelia, are reported. The hydrobiological indices of the Lake Gimoly show that it is a mesotrophic water body with elevated plankton and benthos evolution levels in bays. Its fish population consists of 16 species. The main targets of amateur fishing are vendace, bream and pike. The roach and perch resources are not completely used. Lake Gimoly is a water body of the highest commercial fishing category because it is inhabited by some valuable fish species such as whitefish, pike-perch and vendace.
