Embodiment 1
[0017] 1. Intermediate cultivation of square starworm:
[0018] 1. Conditions for intermediate cultivation ponds: choose a square hard-bottomed cement pond, each with an area of 3 mu, and keep the water depth above 100 cm. The water inlet and outlet of the pond are distributed diagonally, and the outlet is lower than the inlet. It can drain the open air, and can also carry out running water cultivation. A layer of medium-fine freshwater river sand is evenly laid on the bottom of the pool, and the average thickness of the sand layer is about 5-10 cm; the water inlet is installed with a water gate net with a mesh of 80-100 mesh; The pond is equipped with a water pump with a power of 2.2 kW;
[0019] 2. Preparation of the intermediate cultivation pond: 20-30 days before the seedlings are released, use the commercially available snail killer "Snail Killer Yu'an" dissolved in water and sprinkle the whole pond to kill snails and other harmful organisms. Use a concentration of 2-5p...
Embodiment 2
[0027] 1. The intermediate cultivation of the square star worm: each step is identical with embodiment 1.
[0028] 2. Cultivation of square starworms:
[0029] 1. Select the cultivation pond of the gridworm: choose a high-level hard-bottomed cement pond with an area of 3 to 15 acres, and lay medium-coarse sand with a thickness of 30 to 40 cm at the bottom of the pond; if the sand bottom of the pond is deposited by dead algae, moss, The organic substrate composed of feces, residual bait, sludge, etc. is usually foul-smelling and black. Generally, it is washed 1-2 times with a high-pressure water gun to wash away most of the dust and organic matter in the sand, and the ferocious miscellaneous fish, crabs, etc. are manually removed. ; Sow Penaeus vannamei compound feed No. 1 at an amount of 45-60 kg / mu, and plow it thoroughly to mix the feed and sand evenly, increase the fertility of the sand, expose to the sun for 2-7 days, and store water for 50 cm stand-by;
