Forecast of the nutritional value of catfish (Clarias gariepinus) in the spawning period
Abstract In different periods of the life cycle, the chemical composition of fish muscle tissue is subject to significant fluctuations. These changes are most pronounced during the spawning period, when there is a switch to generative exchange. The studies of the nutritional value of the meat of Afr...
