Abstract

The distribution of fishes at early development stages in a 0–100 m water layer (0–bottom) in the northern part of the Central East Atlantic (northern and southern parts of Morocco and Mauritania) is considered using multivariate analysis methods. The distribution of different ecological fish groups at their early development stages can be analyzed using data on the number of eggs and larvae of fish with certain localization patterns. Two independent ecological groups are often differentiated in the study areas: mesopelagic group (far from the coast), which includes representatives of the families Myctophidae and Gonostomatidae, and neritic (coastal) group, which includes representatives of the families Clupeidae and Sparidae. The methodology used for analyzing the material makes it possible to objectively assess the similarity and difference in the species structure and distribution features of mass fishes in their early ontogenesis.

中东部大西洋北部浮游鱼类不同生态族群的空间分布特征

摘要

使用多变量分析方法考虑了中东部大西洋北部（摩洛哥和毛里塔尼亚的北部和南部）0-100 m水层（0-底部）处于早期发育阶段的鱼类分布。可以使用具有特定定位模式的鱼类卵和幼虫数量的数据来分析不同生态鱼类在其早期发育阶段的分布。研究区域通常分为两个独立的生态学组：中古生境组（远离海岸），其中包括Myctophidae和Gonostomatidae家族的代表；以及neritic（沿海）组，其中包括Clupeidae和Sparidae家族的代表。
