THE GROWTH OF SOMATIC STRUCTURES AND MORPHOMETRIC CHARACTERISTIC OF SKELETAL MUSCLES OF A NILE TILAPIA (OREOCHROMIS NILOTICUS L.)
The article deals with some data on the development of fish morphological structures determining their growth on fish-farms. Changes of relative body weight excluding viscera, fish trunk and muscles in post-natal ontogenesis of a Nile tilapia are considered. The values of skeletal muscles fibres, their density, and also the ratio of tissues, indicators determining the quality of fish meat, are provided. For studying growth features of somatic structures the parameters of allometric equations were calculated.
