Popis: | 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. |
