Description
From experiments with two Black Sea fish species: Trachurus mediterraneus ponticus A., and Scorpaena porcus L. the influence of natural mobility, the character of fish movement as well as muscle load on some indices of carbo-hydrate — phosphorus exchange in skeleton muscles was studied. The contents of glycogen (by antronov method), of lactic acid (on reaction with para-oxydiphenil), three fractions of phosphorus combinations: total, inorganic and hydrolyzed, in izobutanol — benzol extract on Malhelbern and Green method was determined (Malhelbern, Green, 1951). It has been shown, that in muscles of active fishes (Trachurus mediterraneus ponticus A.) the level of contents of all determined matters is much higher in comparison with fishes of small activity (Scorpaena porcus L.), Different contents of glycogen in spinal and tail muscle is typical of Scorpaena porcus L. (40,3 and 72,4 mg% correspondingly), while spinal and tail muscles of Trachurus mediterraneus ponticus A. contain practically equal amount of glycolen (123,2 and 128,0 mg%), of lactic acid (52,1 and 51,3 mg%), total, inorganic and hydrolyzed phosphorus (208,2 and 194,1; 146,0 and 143,0 189,0 and 163,0 mg % correspondingly). Great variability of indices of carbo-hydrate exchange in comparison with phosphorus exchange was emphasized. Two hours muscle level (movement in hydrodynamic tube, rate of water stream — 1,2 m/sec) reduces the level of glycogen from 123,2 to 59,7 mg% in spinal muscle and from128,0 to 56,2 mg% in tail muscle. For all that the constant level of lectic acid and insignifia cant decrease of concentration of phosphorus containing fractions in muscles was marked.
