1, breeding site

We have to choose in the formal farm, to choose the smooth lines, swim best effort strong, scales every obvious damage, skin glossy such fry suitable for breeding. We can use the net box to know, and pond breeders 2 methods, it is recommended that we have a net box breeding of high density, easy to manage, natural benefits are also high, so the current farmers are using the net box to carry out aquaculture. Pond farming management trouble, water quality is not good control, too many germs in the pond, it is easy to make grouper sick.

2, breeding conditions

The environment of the breeding sea area is very important, it is best to have no wind on the sea surface, the waves are not too big, there is no storm, the sand on the seabed should be good, and the reefs and coral reefs should be more so that the sea area is most favorable for the breeding of grouper, and the transparency of the sea water of the groupers is required to be at 1.5 cm, and the traffic of the farm should be good so that it is convenient for the transportation of the nursery and the supply of the feeds.

3, stocking density

The stocking density of grouper is very much related to the water flow rate in the aquaculture sea area, and the density of the aquaculture in the fast-flowing sea area can be larger, with a normal length of 3 meters, a width of 3 meters, and a depth of 3 meters of the net box, so that a large net box can be stocked with 2,500 fish fry, with the weight of each tail at 50 grams, and the weight of the fry in the 150 grams can only stock 1,000 fish. The netting is 3 meters deep.

In the growth process of grouper should be timely change the number of breeding net box, 3 meters long, 3 meters wide, 3 meters deep net box can only be if 200 kilograms of grouper, grouper growth rate is very fast to make timely adjustments to ensure that the thin per cubic meter breeding 10 kilograms to 15 kilograms of grouper as well.

4, feeding

Grouper is a carnivorous fish, in the seedlings can be used to cut the fish machine to the fresh fish gate broken pieces for feeding, into the big after you can use the live fish for feeding, grouper feed is very wide, small fish, shrimp, small crabs, can be eaten.

Grouper should pay attention to the feed when feeding, as much as possible to simulate the wild conditions, more change feed. Grouper's digestive speed is not very fast feed once a day can be, but in the water temperature of the weather to increase the number of times a day to feed, because the water temperature is high grouper's body functions will also become stronger, if you do not add the feed, the grouper will be the same kind of phenomenon. When feeding, pay attention to the uniformity of the feed, not to produce will appear grouper growth of different sizes, which has a great impact on the production of breeding.
