Abstract

The European stocks of vimba bream (Vimba vimba) are presently declining, having a "vulnerable" status in some countries. In Romania, there is a lack of scientific studies regarding the species. In order to supplement existing information about this species, specimens of vimba bream were collected from the middle sector of Someș River (Transylvania). Age, length and weight were recorded from 4 sampling points, near gravel quarries. The results show that only young specimens were found. The highest total length value was 22.77 cm, while the highest weight recorded was 121.08 g. Most vimba bream were captured in the first location, where less anthropogenic pressure exists. The populations are in decline in this region because of gravel quarries, among other factors.
砾石采石场可能影响罗马尼亚someau河的Vimba Bream (Vimba Vimba Linnaeus 1758)种群
欧洲的鲷鱼种群目前正在下降,在一些国家处于“脆弱”状态。在罗马尼亚,对该物种缺乏科学研究。为了补充有关该物种的现有信息,从Someș河(特兰西瓦尼亚)的中段采集了vimba鲷鱼的标本。从砾石采石场附近的4个采样点记录年龄、长度和重量。结果表明,只发现了年轻的标本。最高的总长度值为22.77厘米,而记录的最高重量为121.08克。大多数vimba鲷鱼是在第一个地点捕获的,那里的人为压力较小。由于采石场等因素,该地区的人口数量正在下降。
