汉江喜河库区形成对鱼类群落结构的影响
Effects of Xihe reservoir construction on fish assemblages in Hanjiang River
摘要
Abstract
In order to understand the effects of reservoir construction on fish assemblages, a fish?ery resource investigation was conducted on the fish assemblages in the Xihe reservoir of Hanjiang River in autumn 2011 and spring 2012. A total of 35 fish species were collected, belonging to 6 families and 4 orders. Most of the fishes belonged to family Cyorinidae (22 species) and Bagri-dae (7 species). As compared with those collected in 1980-1982, the fish assemblages collect?ed in 2011-2012 changed greatly. The species producing semi-pelagic eggs and preferring to live in riffle declined, while those producing viscid eggs increased. The changes of the other ecologi?cal guilds were related to the spawning types and the preferring to live in riffle. On the whole, the ecological guilds of the fishes in the Xihe reservoir showed convergence in spawning, inhabi?tation, and somatotype. The changes of hydrological conditions resulted from dam construction could be the main causes of the changes of the fish assemblages in the Xihe reservoir. Some ad?vices were given to protect the fish diversity and abundance in the Xihe reservoir of Hanjiang Riv?er.关键词
