根据2004年4月至2005年2月在洞庭湖逐月采集到的胃含物样品,对光泽黄颡鱼摄食习性进行了研究。结果表明,光泽黄颡鱼全年摄食,在繁殖期摄食强度下降。共鉴定17类饵料生物,食物多样性指数春季最高,冬季最低。水生昆虫幼虫和甲壳类为其主要食物,二者在食物中所占重量百分比为90.6%。摄食的水生昆虫主要为蜉蝣目稚虫(数量百分比:24.2%;重量百分比:41.1%)、双翅目幼虫(数量百分比:58.4%;重量百分比:7.5%)和蜻蜓目稚虫(数量百分比:3.2%;重量百分比:22.8%)。光泽黄颡鱼的食物组成在季节上存在明显差异。从数量百分比看,春季和冬季均以双翅目(秋季64.6%;85.0%)为主,夏季以双翅目(28.2%)和蜻蜓目(22.3%)为主,秋季以蜉蝣目(45.7%)为主;从重量百分比看,春季以双翅目(53.0%)为主,夏季以蜻蜓目(55.7%)为主,秋季和冬季以蜉蝣目(秋季53.7%;冬季76.6%)为主。分析表明,光泽黄颡鱼食物组成的季节差异与食物资源的季节动态紧密相关。 |

The present study dealt with the feeding habits of Pelteobagrus nitidus by stomach contents analyses of samples collected monthly from April 2004 to February 2005 in Lake Dongting.Results showed that P.nitidus preyed all the year with its feeding activity being higher in spring and winter than in summer and autumn.Also, the feeding intensity declined in the breeding period.There were 17 prey items being identified.Food diversity was the highest in spring and the lowest in winter.Aquatic insects larvae and malacostraeans dominated the stomach contents, accounting for 90.6% in weight percentage.Aquatic insects consumed by the fish mainly included Ephemeropterans(numerical percentage:24.2%;weght percentage:41.1%), Dipterans(numerical percentage:58.4%;weght percentage:7.5%) and Odonatans(numerical percentage:3.2%;weght percentage:22.8%).Food composition of the fish varied significantly with the season.In terms of numerical percentage, Dipterans(64.6% and 85.0%, respectively) dominated the diets in spring and winter, while Dipterans(28.2%) and Odonatans(22.3%) dominated in summer, and Ephemeropterans(45.7%) did in autumn.In terms of weight percentage, Dipterans(53.0%) dominated in spring, while Odonatans(55.7%) dominated in summer, and Ephemeropterans(53.7% and 76.6%) did in autumn and winter.Analyses showed that the seasonal variations of food composition of P.nitidus were correlated with variations of food resources in the water. |
