Состояние популяции озерного сига Coregonus lavaretus pidschian, Gmelin, 1788, в акватории Забайкальского национального парка (чивыркуйский залив, озеро байкал)

Состояние популяции озерного сига Coregonus lavaretus pidschian, Gmelin, 1788, в акватории Забайкальского национального парка (чивыркуйский залив, озеро байкал)

Abstract

Показано, что популяция чивыркуйского озерного сига является весьма устойчивой, она благополучно перенесла продолжительный (30-летний) промысел. Незначительные изменения структуры быстро восстанавливались, однако в 2010-х гг. сократился промысловый запас, размерно-возрастная структура «помолодела», скорость линейного и весового роста увеличилась, а плодовитость в целом понизилась. Даны рекомендации использования запасов сига. Популяция чивыркуйского сига достаточно стабильна и обладает высокой устойчивостью, сохраняет в целом удовлетворительное состояние запасов, допускающих их эксплуатацию. В соответствии с целями и задачами национального парка, как ООПТ, полагаем, что на акватории парка следует исключить половозрелого сига из «промысловых» видов. Вылов молоди (неполовозрелой части популяции) ограничить приловом в соответствии с Правилами рыболовства при добыче других рыб.

It is shown that population Chivyrkuj lake Coregonus is rather steady, it has safely trans-ferred long (30 summer) a craft. Structure minor alterations were quickly restored, however, in 2010. The trade stock was reduced, the dimensional and age structure "has looked younger", speed of linear and weight growth has increased, and fruitfulness as a whole has gone down. Recommendations of use of stocks Coregonus are made. The Chivyrkuj population has a high stability and resistance, and its stock could be used for commercial expluatation. According our opinion, in the National Park water area. The adult age Coregonus must be excluded among commercial fishering species, and smolt,s fishering must be regulate according Rules of Fishering.
