Abstract—

The paper considers the effect of the Sea of Azov salinization on the food supply to anchovy Engraulis encrasicolus maeoticus as the level of salinity was rising from 12.7 to 14.0‰ during 2014–2018. In 2014 food supply to the anchovy dramatically deteriorated compared with the initial period of the salinization (2006–2013). Small individuals dominant in the population exhibited extremely low lipid content, which appear to have led to a decrease in reproduction and, therefore, the stock decline in the subsequent years. As the population size decreased, the food supply improved; the lipid content in the anchovy body increased by 40–50% in 2015–2018. Fish of the older age groups became dominant in the population, which indirectly suggests a drop in recruitment and the population aging. The work discusses the impact of the change in the fish food resources on the anchovy food supply over the current period of the Sea of Azov salinization (2006–2018)

摘要-

本文考虑了亚速海盐碱化对on鱼cho鱼的食物供应的影响。在2014-2018年期间，盐度水平从12.7上升到14.0‰。与盐渍化初期（2006-2013年）相比，2014年to鱼的粮食供应急剧恶化。在种群中占优势的小个体表现出极低的脂质含量，这似乎导致繁殖减少，因此，随后几年的种群减少。随着人口的减少，粮食供应增加；2015-2018年，lipid鱼体内的脂质含量增加了40-50％。年龄较大的鱼类在种群中占主导地位，这间接表明招聘人数下降和种群老化。这项工作讨论了在亚速海盐渍化时期（2006-2018年）鱼类食物资源的变化对an鱼食物供应的影响。
