Culture techniques of freshwater Pomfret

Pomfret, also known as mirror fish, flat fish, it is tropical and subtropical both edible and ornamental fish, delicious meat, rich nutrition, but also has the role of prevention of cardiovascular disease, but also has the characteristics of few thorns, deeply loved by consumers. Nowadays, what is used for consumption is some farmed freshwater Pomfret. Let's take a look at the culture techniques of freshwater Pomfret.

1. Pond preparation

Pomfret has no special requirements for ponds. Common ponds can be used to raise Pomfret, but the water source is adequate and clear. The pond should be renovated and disinfected before stocking, emptying the pond water in winter, using the sun to whiten it, treating the silt of the pond, setting up water intake and drainage, and making a good filter to prevent wild miscellaneous fish from entering and breeding and fleeing. After the transformation of the pond, it is necessary to sprinkle quicklime on the whole pond for disinfection, generally using 100 kilograms of quicklime per mu, in addition, it is good to prepare aerator and feeding machine.

2. Release seedlings

Half a month before seedling release, 60-80cm was injected into the water, soaked in warm water with tea seed cake and sprinkled in the whole pond to destroy the eggs of other miscellaneous fish in the pond. when organic fertilizer and water were put in, the seedlings could be released when the water color changed to yellowish green. The fish fry should be selected with little difference in size and specification, which is beneficial to the culture and management. Generally, 2000-3000 Pomfret fish with 3cm are released per mu. Before releasing the seedlings, they should be temporarily reared for a period of time in an environment with a water temperature of about 20 degrees. The temporary breeding should be well managed, and some zooplankton or newly hatched nauplii of Artemia should be fed. After a week of feeding, after 15-20 days of cultivation, they can be put into the pond for culture.

3. Feed feeding

Pomfret is omnivorous fish, its food intake is very large, so generally in order to make its rapid growth and achieve high-yield benefits, so generally feed mainly feed, choose to use soybean meal, fish meal, flour and some nutritional additives to prepare granular feed according to a certain proportion. Of course, you can also buy other feed, but it is required that the content of feed protein should be up to 30%, 35%. You should also pay attention to the time and amount of feeding, usually once in the morning and once in the afternoon, accounting for 40% of the total feed in the morning and 60% in the afternoon. The feeding amount should be determined according to the growth condition of the fish and the water temperature of the weather, and the principle of more and less feeding should be carried out. Pomfret should be fully fed without wasting feed. In addition, the feeding power of Pomfret decreases in overcast, rainy and muggy weather, so it is necessary to reduce the feeding amount appropriately.

4. Daily management

When breeding, you should inspect 1-2 times a day, mainly to check the changes of water quality, the condition of the pond surface, as well as the growth and activity of fish. The first thing to do is to strengthen the management of water quality. when it is found that the water quality is getting worse, we should timely inject or change water, keep the water quality fresh, do a good job in fertilizer and water management, keep the water color at yellow-green or tea-brown, and if the color is too dark, we should timely inject water, dilute fertility and dim color, then we should apply organic fertilizer in time to maintain the state of fat and water. The coverage area of aquatic plants on the pool surface cannot exceed 50% of the total area of the pool surface, and it cannot be distributed too densely, so as not to reduce the dissolved oxygen in the water body. When it is found that the dissolved oxygen is insufficient, the aerator should be turned on in time to promote the dissolved oxygen in the water body, especially in the period of changeable temperature in summer. In addition, the residual bait on the pool surface should be fished out in time to avoid affecting the water quality. The growth status of fish is very critical, early growth will be disturbed by a variety of diseases, careful observation, find out the abnormal place of the fish, find out the cause, prescribe the right medicine to make it grow healthily.
