Current state of stocks and harvesting of short-cycle invertebrates in the lakes of the Altai Territory

On the territory of the Altai region, there is an extensive fund of fresh, oligo- and mixohaline, as well as hyperhaline water bodies. The paper provides actual data on the state of stocks and harvesting of invertebrates in the lakes of the Altai Territory. Commercial harvesting is carried out in oligo- and mesohaline, as well as hypersaline fishless lakes. Due to the short lifespan of these aquatic resources, all their production indicators and the state of stocks depend on the environmental conditions. The total stock of gammarids for 2015–2020 was 296 tons; chironomids — 57 tons; chaoborids — 6 tons; cladocerans — 49 tons; copepods — 8 tons; Artemia cysts — 3836 tons. Periods of the most intensive harvesting are confined to June-October for the rational use of their raw material base. The main catches of Artemia cysts and gammarids falls on September (38.0 and 39.3% of the total catch, respectively), chironomids — in September-October (56.9% of the total catch), cladocerans — in July-October (88.6% of the total catch). About 158 tons of gammarids, chironomids, chaoborids, cladocerans and copepods are mined annually, as well as 949 tons of Artemia cysts.
