Can pregnant women eat crispy pomfret? Can crispy pomfret be raised only in Zhongshan?

Its nutritional protein is higher than that of grass carp, but for pregnant women, supplementing nutritional protein every day is beneficial to fetal development and growth. So, can pregnant women eat crispy pomfret? Can crispy pomfret be raised only in Zhongshan?

Can pregnant women eat crispy pomfret?

Yes, pregnant women should eat more fish, as long as they are cooked, they will be fine, and crispy pomfret can also be eaten often.

Can crispy pomfret be raised only in Zhongshan?

Because crispy pomfret was first cultured in Zhongshan Yangtze River Reservoir, ordinary pomfret was cultured in Zhongshan because of its good water quality and pure natural coarse grains.

Finally, a large-scale promotion of aquaculture was carried out in Dongsheng Town, Zhongshan, and it was promoted to the whole country.

Therefore, the cultivation of crispy pomfret depends on the water quality and cultivation technology. Zhongshan has rich experience in this field, and it is difficult to imitate it in other places, so most of today's crispy pomfrets are produced in Zhongshan.

How to breed crisp pomfret?

First, the breeding conditions:

Brittle culture of grass carp can be carried out in ponds or cages. Pond requirements: there is little silt at the bottom of the pond, sufficient water, good water quality, no pollution, convenient water intake and drainage, with an area of 1330-2000 square meters and a water depth of about 2 meters. Before stocking, the pond should be thoroughly cleaned according to routine requirements. Cages can be set in the leeward and sunny places of lakes, reservoirs and rivers. Water quality requirements: no pollution, rich dissolved oxygen, water depth of 4-7 meters, flat bottom and no aquatic plants. Adopt a fully enclosed cage with a mesh size of 5 cm ×4 m× 2.5 m. The bottom of the cage is padded with a 30-mesh gauze as a feeding table to prevent feed loss. The new cage should be launched 7- 10 in advance to soften the box pieces and float some phytoplankton to prevent scratching the fish. Used cages should be cleaned and soaked in 5% quicklime water solution for 30 minutes.

Second, fish stocking:

Grass carp, which is healthy, disease-free and injury-free, and has an average tail weight of 0.5 kg, is selected as the fish species. The stocking amount in ponds is150-250kg/mu, and that in cages is15-20kg/m2. In order to adjust the water quality, the stocking length per mu of pond can be 13- 15 cm. Before stocking, it is best to immunize grass carp, or soak grass carp in 4% salt solution for 5- 10 minutes.

Third, the embrittlement season:

Brittle culture can be carried out when the water temperature is above 15℃ in spring and grass carp stops eating in winter. If the method of round-catching and round-releasing or batch culture is adopted, the embrittlement culture time for each round or batch shall not be less than 60-70 days.

Four, aquaculture management:

Feed is mainly high-protein broad beans, with a small amount of grass, and other feeds cannot be added. At the beginning, you can stop eating for 2-3 days, then feed a small amount of soaked broad beans (you can soak broad beans 1% salt solution for 2-24 hours), and feed them regularly and quantitatively until grass carp can eat normally. Under normal circumstances, the grass carp is fed once a day at about 8: 00 am and 5: 00 pm, and the specific feeding amount should be adjusted according to the feeding situation of grass carp and the change of water temperature. Water temperature 16- 19℃, daily feeding amount of 65438+ 0.5%-2.0% of grass carp weight; The water temperature 19-22℃, and the daily feeding amount is 2.0%-3.0% of the weight of grass carp; When the water temperature is 22-25℃, the feeding amount is 3.0%-4.0% of the weight of grass carp. When the water temperature is 25-28℃, the feeding amount is 4.0%-5.0% of the weight of grass carp. When the water temperature is 28-30℃, the feeding amount is 5.0%-6.0% of the weight of grass carp.
