Embodiment 1
[0028] A method for high-yielding fish farming, which comprises the following steps:
[0029] (1) Build a breeding pond: select a place with a water source to build a pond. The pond includes water inlets and outlets. Inject 7cm deep water into the pond, sprinkle 50kg / mu of quicklime on the water surface, and introduce water into the pond after 8-10 days. Sprinkle a water quality regulator into it and leave it unoccupied for 1-2 days; the depth of the pond is 2.5m, and the bottom silt thickness does not exceed 10cm, where the water quality regulator is photosynthetic bacteria, and the usage amount per mu is 6.0kg;
[0030] (2) Feeding fry: choose fish fry with strong swimming and intact limbs to be put in early March, 400 grass carp weighing 220g / tail, 150 silver carp weighing 100g / tail, and 80g / tail weighing per mu 200 bighead carp and 300 crucian carp weighing 55g / tail. The fry were immersed in baking soda water with a concentration of 1wt% for 22 minutes and fed with cooked egg y...
