Abstract
Fresh histological sections of the Black Sea spiny dogfish have been examined using a 500xSDM electron microscope. Experimental histological sections of the Black Sea spiny dogfish have been made along and across muscle fibers. Sections of skin and adipose tissue between the skin and the muscle have also been examined. PH value in the spiny dogfish muscle layers has been measured using a Kelilong Electron pH-150MI device. Thus, there are three zones determined: the first one is within 24-42 hours of storage with a pH ranging from 6,77; the second one – 46-78 hours with a pH in the range of 6,55; the third one – from 85 to 97 hours of storage with a pH of 6,41. The study of the elastic properties of fish is a study of the deformation properties. Regularities of change of rheological properties of fish depending on term and temperature mode of storage have been established. Graphs of values of deforming force of samples of different shelf life have been obtained, comparison of deformation time and size of deforming values have been made. Results of physical properties are placed in the process of optimizing the parameters of shelf life of the spiny dogfish. Mathematical models describing changes in the basic physicochemical properties of spiny dogfish in different storage parameters are.

According to FAO, consumption of fish itself and fish products has grown up to 20,5 kg per capita over the past year
The surface of muscle fibers is covered with an outer membrane – sarcolemma

Summary
According to FAO, consumption of fish itself and fish products has grown up to 20,5 kg per capita over the past year. The FAO report "State of World Fisheries and Aquaculture" noted the high growth of fishing and consumption in the world, the constant development of aquaculture and effective fisheries management. By 2030, the world's total catch is predicted to grow up to 204 million tons. In 2018, catch amounted almost 179 million tons. It has been studied that fish consumption is one-sixth, and in some countries even half, of the total consumption of animal proteins by the population [1]. The urgent task is the effective use of domestic stocks of aquatic organisms, development of aquaculture and mariculture to obtain products of the predicted level of quality
