Oriental tilapia pond main culture test

The implementation unit is Guangzhi Zhenquan Aquatic Development Co., Ltd., the test pond 16 mouth, water surface 35.6 acres, each mouth area 1.6～1～2 and 0.3 kilowatt impeller aerators 1～2. 10 days before the fry are released, use a 60 mesh sieve to filter the water and fill it with 80 centimeters, and pile 300 about 300 kilograms of fermented and decomposed pig, cow or chicken manure in the pool.
