Grouper farming methods
1. Seedling. Go to the regular farm to choose smooth lines, swim as much as possible, scales have obvious damage, the best luster of the fry, can be used cage farming, has the advantages of high breeding density, easy management, and high natural benefits.
2. Breeding conditions.
Choose the sea surface without wind, the waves are not big, there is no storm to disturb, the sand quality of the seabed is good, the reef, the coral reef is more in the sea area to breed grouper, the sea water transparency is in centimeters, and the traffic should also be convenient, which is convenient for the transportation of seedlings and feed.
3. Breeding density.
The culture density of grouper is related to the seawater flow rate, and the density can be increased appropriately in the sea area with fast flow rate. The general length is 3 meters, the width is 3 meters, and the depth of the cage is 3 meters, which can raise 2,500 fry.

1.

Before stocking the fry, drain the pond water, thoroughly clean and disinfect the pond with quicklime, and apply sufficient fertilizer to fertilize the water quality, so that the fry can eat natural bait when they go down the pond. >>>More
