New technique for raising the largemouth bass in recirculating water in greenhouse
In order to promote the development of high-density,standardized and high-quality rai-sing of the largemouth bass(Micropterus salmoides),high-level round ponds were built in the insu-lation shed in Changshuang Farming Base.The largemouth bass seedlings were raised for 10 months in high-level round pond with circulating water in the insulation shed.The average yield was 2.25 kg/mi with the size of fish 0.8～1 kg/ind.Sales revenue was 78.75 yuan/m2 and the profit was 30.3 yuan/m2.By applying the techque,the fish were raised in high density and land resources were fully used.The breeding period was shortened,while the running cost reduced,and the economic benefit increased
