How to do grouper farming 10, how to do grouper farming

1. Requirements for grouper fry: grouper fry cultivation pond is better than earth pond, and outdoor cement pool can also be used, generally a single pond area of 50 100m3 and a water depth of l 1 5 meters. 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.

2. Grouper fry stocking: Before stocking, the water should be tested. The specifications of stocking in the same pond are required to be neat and the size is consistent.

The stocking density depends on the bait, the level of breeding technology and the cultivation size, and the general stocking density is about 100 m3. Before entering the pond, the fry should be soaked in SOP brine for 15-20 minutes.

3. Feeding: When grouper larvae go down the pond, they feed on zooplankton, and with the growth of fish fry, the amount of feed increases, while the zooplankton in the pond gradually decreases. At this time, one can breed zooplankton through top dressing, and the other can increase the soymilk.

After 15 20 days of cultivation, when the fry reaches more than 3 cm, its feeding properties begin to transform, at this time can be fed surimi on the food table domestication, 2 3 days after adding a small amount of artificial compound feed mixed surimi feeding, after gradually increasing the proportion of artificial compound feed, reduce the amount of surimi, until all with artificial compound feed. The daily bait amount is about 20 of the fish's body weight, and the bait is given 3 times a day.

4. Grouper breeding and cultivation management

1) Adjust water quality: In the process of fish fry cultivation, due to fertilization and bait, the remaining manure residue bait is most likely to spoil the water quality, for this reason, the water should be changed every 3 5 days, and the amount of water changed each time is 1 4 of the pool water. Some aquatic plants such as duckweed or water hyacinth can also be transplanted in the pond to purify the water quality and facilitate the fish fry to hide and eat.

2) Timely feeding: When there is a large difference in the growth specifications of fry, because it has the habit of eating big and small, it is necessary to sieve and feed in time. Fry in the same pond should be of the same size, so as not to affect the survival rate of the fry.

3) Daily management: mainly to patrol the pond to observe the feeding, activities, water color changes of the fry, so as to adjust the feeding amount in time and do a good job in preventing fish diseases.

Blue Ocean Fisheries Platform offers wholesale fry for grouper.

The first thing is to have a space, and the second is to find high-quality seedlings and find sales channels.

How to breed grouper?

1. Environmental requirements.

Artificially cultivated freshwater grouper, if it is pond culture, it is necessary to simulate the marine environment, such as temperature control, the water temperature must be above 28 degrees at the seedling stage, so as to ensure the survival rate of grouper at the seedling stage. For adult groupers, the water temperature should be higher than 33 degrees and not lower than 25 degrees, especially in winter, groupers are likely to cause freezing to death.

2. Pond disinfection.

The pond area is 50 100 cubic meters, the water depth is 1 meter, the bottom of the freshwater grouper breeding pond is sandy, the water quality is pollution-free, and the bottom can be paved with some tires, pebbles, etc., because freshwater grouper has a hobby of burrowing. Before stocking the fry, drain the pond water and disinfect the pond with quicklime to fertilize the water quality, so that the fry can eat natural bait when they go down the pond.

3. Fish fry stocking.

Before the stocking of freshwater grouper, it is necessary to test the water, generally the same breeding pond stocking specifications should be consistent, generally 100 cubic meters, fry in the pond before soaking the fish body in salt water for 15 20 minutes.

4. Seedling management.

Freshwater grouper fry because of fertilization, bait, etc., easy to lead to water quality corruption, so it is necessary to change the water once every 3-5 days, each time the water is a quarter of the pond water, you can also plant some aquatic plants in the pond, can purify the water quality, and is conducive to the fry to hide. When there is a large difference in the growth specifications of the fry, there is a habit of eating big and small, and it is necessary to sieve and raise it in time, and the requirements of the same pool are the same, so as not to affect the survival rate of the fry.

5. Bait feeding.

Freshwater grouper bait has animal bait, as well as plant protein bait, artificial feeding, feed protein content in 35 40%, animal protein should be more than 25%, as well as add some plant protein raw materials, the daily amount of bait is about 20% of the fish weight, 3 times a day, during the feeding can be combined with feed, can also be fed fresh and tender grass, when plankton is insufficient, to the appropriate amount of top dressing to cultivate zooplankton.

6. Disease prevention.

In the process of freshwater grouper breeding, it is easy to have rotten tail disease, rotten gill disease, white spot disease, vibriosis, etc., which has a great impact on its growth, so it is necessary to patrol the pond every day, observe the fish eating, activities, water color changes, etc., and adjust the feeding amount in time and do a good job in preventing fish diseases.

The water used for aquaculture is the natural seawater of the sea area, the water temperature is 14 30, the pH value, the salinity is 23 34 (under normal circumstances, it is about 32), the dissolved oxygen is more than 6 milligrams, the light is 6000 8000 lux, and the direct sunlight is avoided. During the wintering period, the water temperature of the deep well seawater is 25 and the specific gravity is about 21 and the specific gravity is adjusted by natural seawater, and the convection cycle state is maintained for 24 hours.

According to the needs of the growth and development of fry at different stages, the fry body length is raised with a plastic frame (table cover), 5 10 cm is raised in a small plastic cage of 1 meter, and 10 20 cm is directly stocked in a circular cement pond of 10 meters.

When breeding groupers, they should be provided with sufficient space, and the breeding density should not be too large, so as to avoid the phenomenon of hypoxia. The pH value of the water is more suitable to be maintained between 7-9, and the water depth needs to be about 4 meters for large-scale farming, and the dissolved oxygen content should be more than 5 milligrams per liter. The water temperature should also be kept at 22-28 degrees.

It needs to be fed regularly, and live small fish can be fed. In addition, it is necessary to clean the fish tank regularly to prevent diseases. <

Grouper can be farmed. They can be farmed either on a large scale or at home. However, in general, large-scale farming is more common because they are economic fish.

1. Space and density: To breed grouper, we should first pay attention to the problem of spatial simplification and density. To provide sufficient space, the number of groupers should not be too large, if it is too dense, it is easy to have the problem of hypoxia, and the development of groupers will not be good.

2. Water quality: Grouper has certain requirements for the surrounding water environment, and it is necessary to pay attention to regulation. For example, the pH of water should be between 7 and 9, which means that it is better to choose water that is more alkaline.

The second is the amount of dissolved oxygen, which needs to be more than 5 milligrams per liter, because groupers have relatively high requirements for dissolved oxygen in the water. In addition, if the number of aquaculture is relatively large, then the water depth of the breeding pond is more than 4 meters.

3. Water temperature: In addition, groupers also have requirements for water temperature. Specifically, the most suitable range is within the range of 22-28 degrees, and if the water temperature is not suitable, it will seriously affect their growth and development.

In the process of breeding, try to keep the water temperature suitable, not lower than 15 degrees. Therefore, if the water temperature is too low in winter, special attention needs to be paid to regulating it. 4. Feeding:

It is also very important to breed grouper and feed it. Groupers belong to a carnivorous fish and are best served with animal feed as their food. Slippers can be used to feed them some small fish, but care needs to be taken to disinfect them and cut them into small pieces before feeding.

5. Prevention of disease parachain disease: groupers are more prone to diseases from April to August, and the most serious ones are some parasitic diseases. Therefore, it is necessary to do a good job of prevention and control at this stage and disinfect regularly.

<> grouper can be cultivated, at present, artificial breeding grouper mostly adopts the method of cage culture, that is, with the help of the pure natural resources of the sea to carry out the sea area good bending net limb resistant breeding, this practice is not only simple and efficient, but also can save the cost of breeding, grouper can also use pond culture, can be dug in the low and middle tide area, but the pond bottom needs to simulate the sea environment, the water quality is required to be pollution-free, the transparency is high, and the depth of the pond water is more than 1 meter.
