Abstract

The size and age structure and growth of Atherina boyeri from southwestern Crimea were studied. The ratio of males and females was 1.00 : 1.38, the proportion of males decreases in older age groups, and the age limit for both sexes is 4 years. The specific growth rate naturally decreases from 2.29 in the first year of life to 0.25 in the second and to 0.10 in the fourth. Maximum length and weight there are greater in females than males (12.3 cm and 9.25 g vs. 10.8 cm and 7.65 g). It has been established that the growth rate of atherina from southwestern Crimea is higher than that of estuarine and lagoon forms living in labile salinity but lower than that of marine and oceanic ones.

摘要

研究了克里米亚西南部博伊特氏菌的大小，年龄结构和生长。男女比例为1.00：1.38，年龄较大的男性比例有所下降，男女的年龄限制均为4岁。自然增长率从生命的第一年的2.29下降到第二年的0.25和第四年的0.10。女性的最大长度和体重大于男性（12.3 cm和9.25 g，而10.8 cm和7.65 g）。已经确定，克里米亚西南部的动脉粥样硬化的增长率高于盐度不稳定的河口和泻湖形式，但低于海洋和海洋形式的泻湖形式。
