What are the farmed species of Pomfret?

1. Silver Pomfret: silver Pomfret is a warm water middle and lower layer fish, which usually lives in the waters with slow tidal current and water depth of 5m to 110m. It is active in the middle and upper layers of the water in the morning and dusk, and schools of fish are more concentrated in neap tide. Distributed in the Indo-West Pacific region.

2. Pomfret: Pomfret is a warm water pelagic fish. it lives in the tropical, subtropical and temperate areas of the Indian Ocean, Pacific Ocean and Atlantic Ocean. It generally does not form large groups. It swims from the open sea to the offshore in spring and summer and to the deep water in the open sea in winter.

Culture methods of golden Pomfret

1. Seedling selection: the artificial breeding technology of Pomfret has been quite successful, so the size of the seedlings is relatively symmetrical, as long as the fry with normal skin color and large size are selected as long as they are strong and lively, intact and intact. The size of farmed fry is generally about 5 cm.

2. Pond selection: Pomfret culture ponds should choose places with convenient transportation, sufficient sunshine, suitable water depth, intertidal zone, sufficient water source, good water quality and no pollution sources. at the same time, it is best to choose places with sufficient sources of brackish and fresh water or convenient underground water sources.

3, pond conditions: Golden Pomfret culture pond requires regular pond shape, preferably toward the sun, rectangle, east-west direction, size should be based on the status of culture methods and facilities should not be small, water depth of more than 1.2 meters, no leakage, while required to be equipped with aerator.

4. Stocking preparation: in addition to sufficient exposure to the pond, the common medicines in the pond cleaning include quicklime, tea meal, bleach, Croton and ammonia, etc., apply basic fertilizer to cultivate natural bait, test the water with several fish after 10 days of disinfection, and then plan to release seedlings 24 hours later.

5. Fish fry restocking: Golden Pomfret fry is released to avoid high temperature or too cold weather, with a density of 1000-1500 pieces / mu. It is best to domesticate when feeding, and the amount of feed is determined by the reduction of expanded feed floating on the water surface. Generally eat in one day as the standard.

6. daily management: in the whole process of Pomfret culture, fertilizers and oxygen should be added timely according to the transparency of the pond water, pay attention to observe the weather, water quality, fish feeding activities and growth, and take corresponding measures in time when problems are found.

Culture method of Freshwater White Pomfret

1. Pond conditions: the pond area of freshwater white Pomfret is 510 mu, and the water storage depth is more than 1.5 meters. 15 days before putting fish, the whole pond is sprinkled with tea bran 30kg / mu or quicklime 60kg / mu.

2, water temperature control: Pomfret is a warm water fish, the suitable temperature for growth is 15-30 ℃, when the water temperature is lower than 12 ℃ or higher than 36 ℃, it will freeze to death or burn, so it is common to build a cold shelter when breeding.

3. Stocking density: the stocking density of freshwater white Pomfret should be determined according to the actual situation, usually 1500 red Pomfret summer fry with silver carp, bighead carp, common carp, crucian carp and so on.

4. Feed selection: fresh water Pomfret does not have high requirements for feed, and the crude protein is more than 25%. Peanut cake, rapeseed cake, bran cake, distiller's grains and wheat bran can be selected according to the situation. Livestock and poultry feed feces or full-price compound feed can also be selected.

5. Feed feeding: the feed of Freshwater White Pomfret should be regularly, positioned, qualitatively and quantitatively. When the water temperature is above 20 ℃, the daily feeding amount is 40.5% of the fish body weight, and the daily feeding amount of the water temperature 15 ℃ is 2% of the fish body weight. The water temperature is below 15 ℃ without feeding.

6. Water quality management: when the transparency of the freshwater Pomfret pond is more than 30 cm, some fermented chicken manure or pig manure should be put appropriately to make the water quality "green, tender and cool", with a transparency of about 20 cm.

7. Disease prevention and treatment

① watermelon disease: before entering the pool, 2ppm mercurous nitrate was washed for 1 hour and 2 hours. After entering the pool, 0.1~0.15ppm mercurous nitrate was sprinkled all over the pool.

② leukoderma: sprinkle the whole pool with 1ppm bleach, or soak with 12.5ppm chlortetracycline or 25ppm oxytetracycline for 30 minutes.

③ bacterial Gill rot disease: after the attack, 0.025ppm furazolidone was sprinkled throughout the whole pool, once every other day, twice in a row.

④ water mildew: sprinkle the whole pool with 0.1ppm methylene blue once a day for two consecutive days or 30.4% salt water for minutes.

⑤ rotifer and oblique tube disease: the mixture of 1.2~1.5pm copper flow acid and ferrous acid (5:2) was sprinkled all over the pond.
