Common culture patterns of grouper

Grouper is a kind of precious fish, and many farmers want to join it. With the development of culture technology, grouper culture has gradually adapted to local culture. At present, there are four common culture methods. Let's take a look at which four culture models are more common. We can also learn together.

1. Pond culture

Pond culture is changed according to the ordinary way of fish culture, the initial stage is to use fish boxes to culture in the water, convenient for observation and management, and so on, and then put into the pond culture, so the survival rate will be much higher. The breeding time in the fish box is about half a month, and then they will adapt to the culture in the box, which is not conducive to fattening. And in the pond culture of grouper, it is best to mix some other species, so as to ensure the growth of grouper is better, such as silver carp, prawns and so on can be considered.

2. Cage culture in coastal and shallow sea

This method is a common way of culture in coastal areas, and its difficulty lies in finding a high-quality culture base, which has a great impact on the later quality of grouper. It is mainly on the water quality, sediment, flow speed and depth, wind and waves and other aspects to consider, when these are more appropriate, choose floating matter, the bottom of the fish tank for culture. This should pay special attention to density, because high density will cause grouper to attack each other, generally 3-3-3 boxes with about 600 seedlings of 5-10 cm, which need to be reduced appropriately at a later stage.

3. Deep-sea cage culture

As there are fewer and fewer areas suitable for farming in shallow sea areas in recent years, the pressure of competition with each other is greater, and the probability of non-pollution will be greater, many farmers have set their sights on deep-sea aquaculture. However, at present, the technology of deep-sea aquaculture is not very common, and farmers will have a lot of choices when choosing places suitable for breeding grouper, because there are many suitable places, but what farmers consider most about deep-sea slate culture is the issue of safety. one thing to choose a safer point is that there is almost no problem with the culture environment. Its culture method is similar to that of shallow sea culture, except that the number of culture tanks should be appropriately reduced by about 10%, because it is impossible to adjust the culture quantity in time.

4. Factory breeding

This is a more scientific and technological way of breeding, high-tech content at the same time, capital requirements will be more, but farmers are relatively easy, mainly inspection time will be more. Its principle is the one-stop service of spawning, hatching, feeding and fencing, and there are corresponding breeding ponds, isolation ponds and other equipment. If the water quality and environment are adjusted according to their own needs, the quality will be much better, and the return on high investment will not be so bad. Generally engaged in factory farming, there will be matching technical breeding introduction, we will not say more.

The above are several common ways of breeding grouper. At present, they can basically meet the needs of most grouper farmers, but the corresponding varieties of these methods are different. When you breed, you must know what are the restrictions on the species you choose, or how they are not suitable for breeding. If you want more information, you can follow us!
