摘要

研究了亚速海大比目鱼（kalkan）成熟和产卵过程中卵母细胞的形态生理参数。另外还测定了每条鱼性腺的三个区域（颅、中、尾）的脂肪酸组成。在产卵期间，观察了卵的形态生理特征和脂肪酸组成的动态变化。两种生理上重要的脂肪酸，油酸和二十二碳六烯酸，在鸡蛋中占主导地位。二者含量变化趋势相反，产卵初期二十二碳六烯酸含量高于产卵高峰期，产卵高峰期油酸含量占主导地位。

Morphophysiological and Biochemical Characteristics of the Gonads in the Kalkan Scophthalmus maeoticus torosus (Scophthalmidae) during Maturation and Spawning in the Sea of Azov.

Morphophysiological parameters of oocytes were studied in the Azov turbot (kalkan) Scophthalmus maeoticus torosus during maturation and spawning in the Sea of Azov. The fatty acid composition was additionally determined in three (cranial, middle, and caudal) regions of the gonad in each individual fish. The dynamics of the morphophysiological characteristics and the fatty acid composition of eggs was observed over the spawning period. Two physiologically significant fatty acids, oleic and docosahexaenoic, were found to dominate in eggs. Opposite trends were detected in their contents, i.e., the docosahexaenoic acid content at the beginning of spawning was higher than in the peak spawning period, when oleic acid prevailed.
