A successful introduction: the zander has settled down in Lake Sundozero and continues to spread

Scientists of the Institute of Biology KarRC RAS have published the results of long-term observations over the population of the zander (or pikeperch) introduced to Lake Sundozero more than a half-century ago. They confirm the species has become naturalized. Maintaining the population requires regulation of harvesting, protection during spawning, and tending of spawning grounds.
