From April 04 to April 08, 2022 in the “RPC of Fisheries” LLP was held the scientific and practical exchange of experience seminar among hydrochemists, on the subject “Assessment of a conditions of reservoirs of fishery value by methods of the hydrochemical analysis”. The seminar was participated by: O.A. Sharipova, head of laboratory of the Balkhash branch, A.A. Aitkalyeva, head of the test center, S.Y. Dolgopolova, senior researcher, A. Minat, head of the expedition team, Mukatai, researcher.
During the seminar the following questions were considered:

• – selection, preservation and storage of tests of water of the studied reservoirs;
• – methods of determination of hydrochemical parameters in field conditions;
• – determination of ion-salt structure of fresh and salty water objects by titrimetric methods;
• – analysis of influence of abiotic factors on water organisms;
• – planning of hydrochemical researches for the solution of scientific and practical tasks in the fishery industry;
• – working off of methods of carrying out analyses of hydrochemical indicators, for expansion of area of accreditation of SPC of Fishery LLP.

Following the results of a seminar the participants successfully passed the test for the level of development of knowledge and got certificates. Certificates were presented by the deputy CEO S.Zh. Asylbekova.

Works within the project of commercialization of the financed JSC Fund of Science are begun:  “Artificial reproduction and cultivation of fish stock of sazan for the purpose of its further implementation for stocking of natural water reservoirs of the Republic of Kazakhstan”. Catching and bonification of producers of sazan is made. Fish will be divided by sex, seated in special live-fish tanks and transported to pre-spawning ponds for the further spawning action.

Works on electronic digital chipping of sazan by specialists of the “RPC of Fisheries” LLP is carrying out. Electronic fish chipping is one of the most promising technologies today. Today, the presence of electronic identification numbers for farmed fish in every fishery is an indication of the consistent development of new fish farming methods.

Today, within the fishery development program of the Republic of Kazakhstan, a meeting was held between the head of the OIE (Office International des Epizooties) regional office in Nur-Sultan, M.K. Taitubaev and a specialist in fish diseases from Italy, Mario Latini. The meeting was attended by: Deputy Chairman of the Fisheries Committee, A.S. Asylbekova, CEO of the “RPC of Fisheries” LLP, K.B. Isbekov, Deputy CEO of the “RPC of Fisheries” LLP, S.Zh. Asylbekova, Deputy Chairman of the Board of the “Kazakh Research Veterinary Institute” LLP, A.M. Abdybekova, representative of the Association “Kazakh Balyk”, M.T. Tursynali. During this meeting, issues were raised to ensure the conservation and development of the country’s aquatic biodiversity, as well as proposals for organizing a joint international project, which should be aimed at improving the health and well-being of aquatic animals, as well as improving the quality of fish products in the country.

Within the Memorandum of mutual cooperation the “RPC of Fisheries” LLP and VITA LLP held a scientific and practical seminar at the fisheries school “Fish school Shardara” for businessman and fish farmers on the subject “Technologies for growing valuable species of fish and their processing”.

At a seminar the senior researcher of the aquaculture, N.S. Badryzlova was shared with her experience. During the seminar a trip was made to the fish farm of the agricultural production farm “Hamit” for holding a practical lesson.

The order of the acting as the chairman of the Committee of forestry and fauna of the Ministry of Agriculture of the Republic of Kazakhstan of July 24, 2015 No. 190 imposed restrictions and a prohibitions on use of fauna objects, including when fishing in the Republic of Kazakhstan. 

According to the Order of the Balkhash-Alakol Interregional Basin Fishery Inspection (BAMBIRH) dated April 1, 2022 No. 23 н/қ during the spawning period of fish in 2022, a prohibition on fishing was introduced in the Kapshagay reservoir and all rivers and watercourses falling into it from April 15, 2022 to May 30, 2022 (inclusive).

The timing of the introduction of a prohibition on fishing on Lake Balkhash and the Alakol system of lakes, as well as in other regions of the republic, will be announced additionally, based on the results of a study of these reservoirs for the temperature regime and maturation of the gonads of commercial fish species. Detailed information on all regions of the country is available on the website of the information and legal system of regulatory legal acts of the Republic of Kazakhstan – Adilet, as well as on the website Egov.kz. When fishing, it is necessary to strictly comply with the established of the law requirements, for the violation of which both administrative and criminal liability is provided.

From March 30 to April 06 employees of the Balkhash branch the “RPC of Fisheries” LLP carry out research work on the Ili River (Tasmurun district) within framework of the Agreement under program 256, subprogram 102.

Expeditionary work includes:

• – Daily monitoring of the temperature regime of the Ili River;
• – Selection of hydrochemical and hydrobiological samples;
• – Nets measurements of fish of each species were made, taking into account the temporary instructions, taking the length, weight, scales for age;
• – Selection of mature commercial fish species for determine absolute individual fertility (AIF).

The objects of research are commercial fish populations and hydrobiocenoses.  Material is being collected for the development of a biological justification for the limits of fish catching and other water animals on the Ile River.

The obtained scientific data on the status of fish stocks, their biological characteristics are the basis for calculating catch limits and developing a strategy for careful management of stocks and ensuring sustainable fishery, optimal distribution of fishing efforts in the water area of reservoirs.

For the period of research work, the spawning course of asp was noted, according to the result of catches from 100 specimens of caught asp: 42% finished spawning, 52% at stage IV, 6% are juvenile. Works on catching asp are carried out by floatable nylon fishnets. 

On April 2, 2022, as part of the control fishing with participation of the Balkhash-Alakol Interregional Basin Inspection of Fishery and the “RPC of Fisheries” LLP, a comparative experiment was begun on the selectivity between of the traditional fishing gears (nylon nets) and the monofilament (fishing line) with a cell pitch of 30 to 100 mm. 

This experiment will last for 10 days, as a result of which fishing gears with a minimum size of the constructive cell pitch will be recommended, which will not allow the possibility of by-catch of juvenile fish (non-commercial sizes, that is, immature specimens) in order to further preserve and ensure the reproduction of fish resources.

We invite all interested parties to participate in this action!

Systematically related species are species that came into the environment specifically or accidentally, in addition to their main habitat. These species adapt quickly, when the environment for them is  favorable. Alien species are widely distributed throughout the world and are found in all categories of living organisms (plants, animals, fish, etc.) and in all types of ecosystems.

According to the latest data, black bream, whitefish, tilapia, snakehead live in the Ili River and the Kapchagai reservoir. Almost all of this fish came from neighboring China, that is, from the transboundary Ili River. Exotic species have a negative impact on biodiversity, ecosystems, and populations. They lead to habitat changes, competition for nutrients, predation, disease and loss of genetic diversity.

Scientific research is needed to determine the presence of alien species in water reservoirs. Preservation of biodiversity is an urgent problem today. This is reflected in the Convention on Biological Diversity. In order to resolve this issue, the “RPC of Fisheries” LLP has begun to conduct research within the Program “Comprehensive assessment of the status of fish resources and other hydrobionts of the main fishery reservoirs of Kazakhstan and development of evidence-based recommendations for their sustainable use.”

During the research, the following works were carried out:

• a general monitoring of the catches of recreational fishermen was carried out;
• the species composition of the caught fish was determined;
• the biological indicators of these fish were taken;
• experiments were carried out with winter rods to determine the catchability of various fishing equipment and baits.
