Whitefishes of Yakutia water bodies: stock state and prospects for fishing development
Basic fishing objects of Yakutia water bodies are 20 species of freshwater fishes, leading role is played by whitefishes (Arctic cisco, peled, least cisco, whitefish, broad whitefish, muksun). Today only Lena populations of Arctic and least cisco and muksun are stable and their stock is underexploited. Populations of whitefishes of Eastern Yakutia are in hard state. To protect the population of hemi-anadromous whitefishes the authors propose to move main fishing in river channels because in deltas all age groups are feeding and therefore by-catch of immature fish is about 90%. This factor is accountable for diminishing the fishes stock. It is expedient, also, to provide for obligatory fishing of fishes of little use (roach, perch, eelpout, dace) when distributing quotas among users.
