研究了碧流河水库鲢鳙鱼类在低温(水温12℃以下)下活动规律及其对网具的反应,并在渔具和低温捕鱼技术方面作了改进尝试。1995年和1996年分别捕鱼82 350 kg 和167 230 kg,日产量和日经济效益分别是试验前的2.29和2.54倍。
The activities of silver carp and bighead carp in the Biliuhe reservoir at low temperature (water temperature below 12 ℃) and their response to the nets were studied. At the same time, attempts were made to improve fishing gear and low temperature fishing techniques. In 1995 and 1996, respectively, fishing 82 350 kg and 167 230 kg, daily output and economic benefits were 2.29 and 2.54 times before the test.
