Abstract

The age and sex composition of the schools, food activity, the age of sexual maturity, breeding period and fecundity of the alien species Prussian carp indicate the presence of favorable environmental conditions for its wide distribution in the reservoirs of Armenia. The ratio of female/male of Prussian carp in most of the studied reservoirs was 3 : 1; most of the fish were diploids. The age composition of Prussian carp usually has 4 age groups, with maximum of 7 groups, and a minimum of 3 age groups. The age of sexual maturity of Prussian carp differs in the northern (1+ to 4+) and southern (0+ to 3+) populations in Armenia, as well as in flowing and stagnant water bodies. In some reservoirs, the percentage of Prussian carp in catches has increased over the past decades, which negatively affects the local fish species composition. This fact may indicate the formation of the invasive populations of Prussian carp in Armenia.

亚美尼亚水体中外来物种普氏鲤（鲤科，动鳍目）的生物学特征

摘要外来物种普氏鲤的鱼群年龄和性别组成、摄食活动、性成熟年龄、繁殖期和繁殖力表明，亚美尼亚水库中存在有利于其广泛分布的环境条件。在所研究的大多数水库中，普氏鲤的雌/雄比例为 3:1；大多数鱼为二倍体。普鲁士鲤鱼的年龄组成通常为 4 个年龄组，最多 7 个年龄组，最少 3 个年龄组。亚美尼亚北部（1+至 4+）和南部（0+至 3+）的普鲁士鲤性成熟年龄不同，流水体和死水体的性成熟年龄也不同。过去几十年来，在一些水库中，普鲁士鲤鱼在渔获量中所占的比例有所增加，这对当地鱼类物种组成产生了不利影响。这一事实可能表明亚美尼亚形成了普氏鲤入侵种群。

期刊介绍： Russian Journal of Biological Invasions publishes original scientific papers dealing with biological invasions of alien species in both terrestrial and aquatic ecosystems and covers the following subjects:description of invasion process (theory, modeling, results of observations and experiments): invasion corridors, invasion vectors, invader species adaptations, vulnerability of aboriginal ecosystems;monitoring of invasion process (reports about findings of organisms out of the limits of natural range, propagule pressure assessment, settling dynamics, rates of naturalization);invasion risk assessment; genetic, evolutional, and ecological consequences of biological invasions of alien species; methods, means of hoarding, processing and presentation of applied research data (new developments, modeling, research results, databases) with factual and geoinformation system applications;use of the results of biological invasion research (methods and new basic results) under the study of marine, fresh-water and terrestrial species, populations, communities and ecosystems; control, rational use and eradication of the harmful alien species..
