Abstract In recent years, the decrease in precipitation due to global warming or the change of precipitation regime has led to the review of production methods in agricultural activities in the world and in Turkey. Accordingly, scientific studies continue to develop appropriate methods that can keep up with today's conditions in the agricultural, animal and fishery production sectors in order to use water resources more efficiently. From the point of view of fish production, sustainable production in both marine and inland waters, obtaining more products per unit area, more efficient use of resources, reusing the water used in production and discharging it are ensured to conserve resources. Biotechnological studies continue to increase day by day in order to protect resources, reduce losses in production amount and improve product quality. In this review, biotechnological methods applied in fisheries today are emphasized for target production by eliminating product losses.
