摘要:
总结了在花园湖渔业开发技术中云南滇池高背鲫移殖的研究工作。结果表明,移殖后很快形成稳定的种群,鲫鱼总产从1986年的16.12×104kg提高到1989年的33.3×104kg,经济效益、社会效益和生态效益均较显著。

Abstract:
Huayuan Lake in Anhui Province has abundant resources of aquatic weeds and high-quality water, favorable for the growth and spawning of crucian carp.However, the production of crucian carp in the previous years only accounted for over 35.1% of the total catch in the lake because of its slow growth rate.In the recent years, high dorsal crucian carp, a triploid fish with a fast growth and high reproductivity, was introduced from Dianchi Lake in Yunnan Province Into Huayuan Lake, thus, forming a spawning population in the following years.The production in the 1st, 2nd and 3rd year after the introduction occupied 15%, 23.8% and 33.3% respectively.As a result, the total production of crucian carp was increased from 161200 kg in 1986 to 330000 kg in 1989,in which high dorsal crucian carp was up as 116000 kg.Through the analyses of its growth, feeding habit, spawning and other parameters 9 it is concluded that high dorsal crucian carp is growing well and the percentage of its production to the total catch in the lake is increasing year after year.Moreover, high dorsal crucian carp population is being stabilized in the lake, acquiring excellent social and ecological efficiencies.
