A native population of landlocked salmon of the Pista River was investigated in 2000-2002. Adult salmon in Pista River has smallest size among other populations of landlocked salmon in Karelia. Data on the biology and parasite fauna of young salmon are presented. The presence of local salmon populations in lakes of the river system is apparently one of the mechanisms keeping the magnitude of population. The presence of Gyrodactylus salaris, a harmful parasite of the young landlocked salmon, is established in this territory for the first time. This monogenean species is believed to have been introduced into the Pista River via stocking from Finland.
2000年至2002年，对皮斯塔河内陆鲑鱼的本地种群进行了调查。皮斯塔河的成年鲑鱼在卡累利阿其他内陆鲑鱼种群中体型最小。文中给出了幼鲑的生物学和寄生虫群落数据。河流系统湖泊中本地鲑鱼种群的存在显然是维持种群数量的机制之一。首次在该地区发现了内陆幼鲑的有害寄生虫——鲑三代虫。据信，这种单殖吸虫物种是通过从芬兰引种进入皮斯塔河的。
