Особенности функционального состояния черноморской ставриды в разные периоды жизненного цикла
Data on the features of the Black Sea horse mackerel annual cycle and gametogenesis are presented. A relatively long spawning period (up to 4 months) influences metabolism of the horse mackerel specimens. During the pre-spawning period, high fat and protein content in liver and muscles is maintained in their body, which is necessary for the gametogenesis process to take place. The long spawning period of the studied species results from the intermittent maturation of reproductive products and presence of oocytes from different generations in the horse mackerel's ovaries. In the spawning period, increase in protein and fat content in gonads and decrease in fat content in muscles and liver almost in 2 times is recorded. After prolonged spawning, rapid restoration of the horse mackerel physiological state occurs due to high metabolic rate. As its feeding period ends, horse mackerel moves to its wintering sites. High fat content in tissues (up to 45 % in muscle tissue and 51 % in liver) allows it to survive winter successfully, because under the decreased water temperature, it is almost inactive and feeds scarcely.
