EXPERIENCE OF RAISING OF TILAPIA (OREOCHROMIS NILOTICUS) IN PONDS ON GEOTHERMAL WATER

Abstract

Аrticle written based on results of work carried out within the framework of joint international scientific and technological project №2019E01013 "Study and implementation of technology for highperformance growing of tilapia fish in Kazakhstan". Article presents biotechnical methods of raising of tilapia in polyculture with Clarium catfish in ponds on geothermal water. Shows data on raising tilapia at high stocking densities using a Chinadeveloped automatic forage spreader and aerator to increase oxygen content of water. Results of monitoring indicators: temperature and oxygen indicators, hydrogen index are presented. Data on dynamics of abiotic environmental factors and their influence are presented. Analysis of fishbreeding biological indicators is presented; factors influencing rate of their growth and survival are determined. Data of statistical studies of production capabilities are presented. Fundamental possibility of growing thermophilic aquaculture objects on geothermal water of fish farms in Kazakhstan is shown, expressed in good survival and high fish productivity.
