Fishes in MZNA-VERT: cyprinid and salmonid communities in the rivers Erro and Urederra (Spain). PhD project, Cristina Garc?a-Fresca

The presence, condition and structure of fish communities are an essential part in fluvial ecosystems because they affect invertebrate communities, plants and other vertebrates. The knowledge of the factors affecting fish populations is necessary for the good management of the rivers. In this study, cyprinid and salmonid species are studied on the Urederra and the Erro rivers to determine their health and conservation status (Garc?a-Fresca, 2003).

鱼类群落的存在状态、健康状况与群落结构，是河流生态系统的核心组成部分，因其会对无脊椎动物群落、水生植物及其他脊椎动物群落产生影响。明晰影响鱼类种群的各类因素，是开展河流科学管护的必要前提。本研究以乌雷德拉河（Urederra）与埃罗河（Erro）为研究区域，针对鲤科鱼类（cyprinid）和鲑科鱼类（salmonid）展开调查，旨在明确其健康状况与保护现状（García-Fresca, 2003）。
