土池主养半刺厚唇鱼关键技术及效果研究

Study on the Key Techniques and Effects of Mono-culture Acrossocheilius Hemispinus in Earthen Ponds

为探索半刺厚唇鱼人工养殖技术,在福建省淡水水产研究所苗种繁育协作基地C区4号池(面积1150m^2)开展土池主养半刺厚唇鱼试验。结果表明:土池主养半刺厚唇鱼当全长达12cm以上时,即可采取干塘全部起捕上市,整个养殖试验周期约12个月,综合饲料系数约为1.43。试验收获的商品鱼总产量为1109.95kg,其中半刺厚唇鱼商品鱼总产量为343.65kg,平均每667m^2产量199.8kg,成活率约67.3%。养殖试验总产值为29532元,其中半刺厚唇鱼的产值为20619元,占总产值的69.8%,平均每667m^2产值11987元;养殖总利润为7576元,平均每667m^2利润约4405元。

In order to explore the artificial culture technology of Acrossocheilius hemispinus, the experiment of mono-culture Acrossocheilius hemispinus in earthen ponds was carried out in Pond No.4 (having an area of 1 150 m^2) in Area C of the larval rearing cooperative base of Fujian Institute of Freshwater Product Research. The results showed that when the total length of the fish reached more than 12 cm in the earthen pond, the fish could all be caught and put on the market in the dry ponds. The whole breeding test cycle was about 12 months, and the comprehensive feed coefficient was about 1.43. The total production of marketable fish harvested in the experiment was 1 109.95 kg, among which the total production of Acrossocheilius hemispinus was 343.65 kg, with an average yield of 199.8 kg per 667 m^2 , and the survival rate was about 67.3%. The total output value of the cultivation experiment was 29 532 yuan, among which the output value of Acrossocheilius hemispinus was 20 619 yuan, accounting for 69.8% of the total output value, with an average output value of 11 987 yuan per 667 m^2 . The total profit of the cultivation was 7 576 yuan, and the average profit was about 4 405 yuan per 667 m^2.
