Abstract

Abstract A study of the interannual variability of the size-age composition of M. barbatus ponticus, inhabiting the south-western shelf of the Crimea, was carried out over a five-year period (between 2016 and 2020). The influence of habitat temperature on growth rate is considered. Equations obtained characterize the size-weight growth of M. barbatus ponticus. The influence of the sea temperature on the development of individuals is considered. It is shown that with an increase in the average annual water temperature, the average annual length (correlation coefficient r = 0.97), weight (r = 0.96) and condition factor (r = 0.93) of individuals increase. It was found that red mullet has a positive allometric growth in the study area. The analysis showed that there was a close correlation between changes in the average annual temperature and the allometric growth rate b (r = 0.97). The equations of length growth of M. barbatus ponticus showed retarded linear growth of the fish living on the south-western shelf of the Crimea in comparison with other areas, Sinop region (Black Sea) and the Aegean Sea. The comparison of the effect of temperature on the size and weight parameters of M. barbatus ponticus living in the south-eastern part of the Black Sea (Sinop region) and the Aegean Sea is carried out; general patterns and differences are noted.

非生物环境因素对红苗生长速率的影响

摘要：在五年的时间里（2016年至2020年），对居住在克里米亚西南陆架的斑背M.barbatus ponticus的大小-年龄组成的年际变化进行了研究。考虑了生境温度对生长速率的影响。所获得的方程表征了倒钩M.barbatus ponticus的大小-重量生长。考虑了海水温度对个体发育的影响。结果表明，随着年平均水温的升高，个体的年平均长度（相关系数r=0.97）、体重（r=0.96）和条件因子（r=0.93）均增加。研究发现，红乌鱼在研究区具有正的异速生长。分析表明，年平均气温的变化与异速生长率b密切相关（r=0.97）。与其他地区、锡诺普地区（黑海）和爱琴海相比，生活在克里米亚西南陆架的斑刺鱼的长度生长方程显示，斑刺鱼线性生长迟缓。比较了温度对生活在黑海东南部（锡诺普地区）和爱琴海的斑背M.barbatus ponticus的大小和重量参数的影响；注意到了一般模式和差异。

期刊介绍： The Croatian Journal of Fisheries was established in 1938 and today possesses a long-term tradition of publishing papers that deal with both freshwater and marine fisheries. Areas covered by the Journal include ichthyology, aquaculture, ecology and diseases of fish and other aquatic organisms, problems of open waters and other topics related to the fisheries field. Prior to publication, articles pass through rigorous review by senior scientists from around the world. The Journal features articles that reflect original research, interpretative content and subject matter of interest to the fisheries profession.
