Work continues on monitoring studies of hyperhaline reservoirs in the Altai Territory

Specialists from the Altai branch of the Russian State Research Center “All-Russian Research Institute of Fisheries and Oceanography” (VNIRO) conducted research in the hypersaline water bodies of the Altai Territory from July 21 to August 2.

 

The main objective of the research was to assess the living conditions and sexual maturation of the second-generation Artemia crustacean, as well as the prospects for further development of the population. The work was carried out on 28 water bodies, of which: 17 lakes were surveyed as part of monitoring the aquatic biological resources and their habitat, 11 water bodies - as part of reconnaissance studies of potentially productive water bodies of the Altai Territory. Hydrobiological surveys were conducted on 7 water bodies using a motor boat along a grid of stations.

 

During the trip, phytoplankton samples, quantitative and qualitative samples of zooplankton, zoobenthos samples (soil and bottom sediment samples), Artemia samples (at the cyst stage), and water samples for hydrochemical analysis were collected. The habitat of aquatic bioresources was measured for the following parameters: transparency, depth, salinity, temperature, hydrogen index (pH), dissolved oxygen in water.

 

Work was carried out on determining the fecundity of Artemia on live material in most of the reservoirs.

 

The collected material was delivered to the branch laboratories for further office processing. The results obtained will serve as the basis for developing a forecast for the state of the Artemia population for the coming years.
