Time-based method for determining fish abundance in fishing rivers

Vestnik of Astrakhan State Technical University. Series: Fishing industry, 2020
The article touches upon the problem of the rational use of fish stocks in fishing water bodies, which implies using modern accounting methods for fish abundance and fish stocks. To this end, instrumental surveys are carried out. In the fishing rivers of Kazakhstan (the Zhayik and Kigash Rivers) there was previously used the biostatistical method of ...
