Sea pomfret can be cultured artificially.
Take golden pomfret as an example
1. Cultivation conditions
The water quality is fresh and pollution-free, the pH is 7.-8.2, the salinity ranges from 5 ‰ to 12 ‰, the ammonia nitrogen content is less than .5mg/L, and the nitrite content is less than .1 mg/L.
2. Pond renovation and pond cleaning and disinfection
After the dry pond is exposed in winter, it is ploughed and leveled, and the bank of the pond is reinforced and raised, and the leakage and collapse of the intake and drainage gates are repaired to remove excessive silt. A temporary pond with an area of 1 mu-1.5 mu is built in the pond. After the transformation, 1kg quicklime is used to make water per mu, and then it is sprayed and disinfected in the dry pool.
3. Seed placement and management
15 days before seedling placement, 8cm of water is injected, and each mu is soaked in 1-15 kg of tea seed cake warm water for 24 hours, and then spilled in the whole pond to kill wild fish eggs. Apply 1kg~15kg fermented organic fertilizer per mu, and when the pond water is yellow-green or tawny, fry can be prepared.
By mid-May, when the water temperature reaches 2℃, 2,5 desalted pomfret fry with a body length of 2.5-3 cm per mu will be stocked. The fry were purchased from Xiamen and first put into a temporary pond for cultivation. 2 fry with a body length of 5 cm-6 cm and 4, fry with a body length of 1.5cm are polyculture per mu, and directly put into Datang. When the seedlings are released, the pond water is brown and rich in natural bait organisms, with transparency of 3cm and salinity of 8‰.
the fry of pomfret pomfret is inflated and oxygenated in the temporary culture pond for 24 hours. After 2 days of feeding, zooplankton or newly hatched Artemia nauplii are fed. After 1 week, minced surimi is added, 3% powdered eel compound feed is added, mixed and kneaded into small balls, and put into the feed. Each temporary culture pond is placed with 6-8 feed, every day. After 2 days' cultivation, the length of the ovate pomfret is 4cm-5cm, and the temporary culture pond can be opened to let the fish species enter the pond.
4. Breeding management
Feeding management. Pomfret was fed with puffed pellet feed specially for pomfret with crude protein content of 43%, and mixed mullet and Penaeus monodon were not fed separately. Choose different types of feed according to the size of fish, with # and 1# feed in the early stage and 2# and 3# feed in the middle and late stage. Adjust the feeding amount flexibly according to the climate and water quality. Generally, feed less in low temperature and rainy days and more in sunny days.
Feed the fish twice a day at a water temperature of about 2℃, and the daily feeding amount is 8%-1% of the fish weight; From June to September, when the water temperature is 25℃-35℃, the golden pomfret eats vigorously and grows fast, feeding 3-4 times a day, and the daily feeding amount increases to more than 15% of the fish weight; In hot and muggy weather, the amount of bait should be controlled moderately to avoid overeating of golden pomfret.
daily management. In daily management, we should patrol the pond at least three times in the morning, at noon and at night, observe the feeding situation of pomfret, find out the reasons when finding abnormal feeding or dead pomfret, and deal with the symptoms in time. Check the filter screen at the inlet and outlet regularly, remove sundries, replace it in time if it is damaged, pay attention to the change of water quality, and add new water in time if it is found that the pool water is deteriorating.
Extended information
Body shape and habits: The body shape is similar to that of a piranha. It's about 2 centimeters long. The whole body is silvery white, and the fins from the lower jaw to the abdomen, buttocks and buttocks are all red during estrus. Silver pomfret is gentle, does not attack other fish, and can be mixed with other large fish.
I like slightly acidic soft water, and my living conditions are not harsh. Omnivorous, love to eat aquatic plants, it is not suitable to plant grass in the feeding tank, otherwise it will be eaten up. They also eat animal bait. Love to swim in groups, strong physique and easy to raise.
