Expeditionary team of the laboratory of ichthyology LLP “Research and production center of fisheries” consisting of: head of the expeditionary team Karlybayuly S., junior researcher of the laboratory Otegen S., senior laboratory assistant Igilik R., carry out research work on the Lower Kolsai lake.

As a result of the work, the expedition team took samples of ichthyological materials for analysis. Starting from April 20, 9 net settings were made (ichthyological order of nets). As a result, 129 trout specimens were caught and processed for bioanalysis. For fertility analysis, material was selected from 50 specimens.

The work is attended by the representative of the State Scientific and Production Enterprise “Kolsai Kolderi” Bolatuly A.

These works are carried out within the framework of the budget program 256 Management, ensuring the conservation and development of forest resources and wildlife, under subprogram 102 Ensuring the conservation, reproduction and rational use of wildlife resources.

In connection with the wide spread of commercial sturgeon breeding in Kazakhstan over the past 15 years, back in the 2000s, the formation of brood stocks (RMS) of various sturgeon species was initiated in order to provide commercial farms with their own fish stock. The formation of RMS of sturgeons, organized earlier in the conditions of fish farms, was carried out chaotically, since at that time there was a reorganization and transformation of existing farms under the prevailing economic conditions in the Republic of Kazakhstan. Taking into account the inferiority of such RMS of sturgeons, formed in the conditions of commercial sturgeon farms, it was necessary to carry out a genetic analysis and reform the RMS taking into account their genetic, age and sex structures.

The newly created farms were based on the bases of RAS (recirculating water supply installation), the use of which in the econometric conditions of the Republic of Kazakhstan showed their non-viability without a clear structuring of processes and a targeted reduction in the cost of manufactured products. The mass selection method was mainly used, in which the majority of individuals from the same age group were selected annually. This selection method does not take into account either gender or family ties within the formed RMS. In the current situation, in order to assess the quality of the formed RMS, it is necessary to use the most modern methods for monitoring genetic processes occurring in artificially reproducible industrial sturgeon stocks. The genetic monitoring system makes it possible to assess the degree of genetic relationship of individuals involved in obtaining reproductive products for the purpose of artificial reproduction, as well as to identify the offspring obtained from genotyped producers.

With the ban on catching sturgeon species from a natural reservoir, farms involved in the export and import of sturgeon products (caviar, salmon, sturgeon meat, fish stock) must carry out genetic certification and have genetic passports for sturgeon fish to confirm that the fish that is on farm is legal. A genetic passport is drawn up for an individual with an electronic PIT tag and contains individual genetic data used for genetic certification.

Conducting genetic research makes it possible to make optimal pairs of crosses between females and males in order to exclude inbreeding and obtain viable young, to limit the legalization of poaching products.

Considering all of the above, in the course of implementing the project “Formation and effective use of sturgeon brood stocks, taking into account their genetic diversity in the conditions of sturgeon fish farms of the Republic of Kazakhstan”, LLP fulfills the tasks of the project:

Evaluation of the genetic polymorphism of RMS of sturgeon species of fish kept at sturgeon hatcheries in the Atyrau region;

Formation of brood stocks of sturgeon species at fish farms in the Atyrau region, taking into account their genetic diversity.

Work is currently ongoing at the commercial fish farm LLP “Caspian Roayl Fish” and the object of research is the RMS of sterlet, formed under the conditions of RAS. The following types of work are currently being carried out:

biomaterial is collected for genetic analysis; photographic materials for the formation of genetic passports;

collection of primary data on fish-breeding biological and morphometric parameters.

Based on the results of the work, an assessment of the genetic polymorphism and fish-breeding and biological indicators of RMS sterlet contained in Caspian Royal Fish LLP will be carried out.

To date, research continues on the river. Zhaiyk on the research vessel “D.Amangaliev” within the framework of the project “Ecological and genetic monitoring of sturgeon species of fish of the Zhaiyk-Caspian basin”.

On the example of stellate sturgeon, methods of acoustic tracking of sturgeon species are being tested, which will make it possible to determine the spawning sites of sturgeons in order to develop recommendations for the protection and passage of spawners to spawning sites. To do this, acoustic tags are installed on stellate sturgeon spawners during their lifetime by sending a signal at a frequency of 76 kHz, which is picked up by hydrophones from the hydrophone, the signal is transferred to an acoustic mobile receiver. The receiver (receiver) is located on the water transport, which follows the tagged fish along the Zhaiyk River after release. The marks are placed on the dorsal or pectoral fin of the fish. Acoustic signals can be tracked at a distance of 220-300 m.

The work is attended by the Deputy General Director, Doctor of Biological Sciences. Asylbekova S.Zh., Scientific Researcher of the Laboratory of Hydrobiont Genetics Shalgimbaeva G.M., Scientific Researcher of the Laboratory of Aquaculture Maratova G.M. employees of the Atyrau branch of LLP Scientific and Production Center for Fisheries and the Zhaiyk-Caspian Basin Inspectorate for Fish Protection, Volkov A.A. ch. Researcher, Laboratory of Molecular Genetics, VNIIPRKh, Moscow.

Today, R&D of the PCF on aquaculture “Formation and effective use of sturgeon brood stocks, taking into account their genetic diversity in the conditions of sturgeon fish farms in the conditions of the Atyrau region”, to control the maturation of RMS of the sterlet herd, assess genetic polymorphism, morphometric and conformation indicators contained in sturgeon fish breeding enterprise Caspian Royal Fish LLP.

The head of the PCF Program, Deputy General Director, Doctor of Biological Sciences, is participating in the work.
