CATDOLL : CATDOLL: Is pomfret a deep-sea fish? Can it be farmed?

There are many varieties of pomfret, some of which are deep-sea fish, and some of which are not deep-sea fish, or even marine fish. Specifically speaking, the knife pomfret lives in deeper seas and is a deep-sea fish. Varieties such as the silver pomfret and the Chinese pomfret live in shallow seas and are nearshore fish. In addition, there are varieties like the red pomfret that live in freshwater. They are neither deep-sea fish nor nearshore fish, but freshwater fish. 1. Is pomfret a deep-sea fish? Pomfret is an edible fish, and there are many varieties of pomfret. Among them, most pomfret varieties live in the ocean and are marine fish. However, the specific water depths of different varieties of pomfret are different. Among them, some are distributed in the near sea, such as the "silver pomfret", which belongs to the fish in the middle and lower layers of the near sea, and the specific distribution depth is between 5-110 meters, so they are not deep-sea fish. In addition, some varieties are distributed in deeper waters, such as the "knife pomfret", which is distributed in the deeper waters of the Indian Ocean and the Pacific Ocean. Some species, such as the "golden pomfret", will swim from the open sea to the near sea in spring and summer, and will swim to deeper places in the open sea when winter comes. Therefore, whether pomfret is a deep-sea fish depends on the specific species.

In addition, there are some pomfret species that do not live in the ocean, such as the "red pomfret", which can live in fresh water, can be raised artificially, and can also be used as an ornamental fish species. They are not marine fish, let alone deep-sea fish.

2. Can pomfret be artificially bred? As mentioned above, there are many different varieties of pomfret, most of which live in the ocean. This part of fish generally cannot be artificially bred, because they have adapted to the seawater environment and cannot adapt to the artificial breeding environment in a short period of time, and sometimes they even die because they cannot adapt to the environment. But some varieties are different, such as the "red pomfret" introduced above. They are also called "freshwater white pomfret" and can live in fresh water. They can be artificially bred and used as ornamental fish.

Sea pomfret can be cultivated artificially.

Take golden pomfret as an example

1. Breeding conditions

The water quality is fresh and pollution-free, with a pH of 7.0-8.2, a salinity range of 5‰-12‰, an ammonia nitrogen content less than 0.5mg/L, and a nitrite content less than 0.1mg/L.

2. Pond renovation and pond cleaning and disinfection

After the winter idle pond is exposed to the sun, it is plowed and leveled, the bank is reinforced and raised, the leakage and collapse of the inlet and outlet gates are repaired, and excessive silt is removed. A temporary holding pond with an area of ​​1 to 1.5 mu is built inside the pond. After the transformation, 100 kg of quicklime is used per mu to dissolve in water and then sprayed on the dry pond for disinfection.

3. Seedling placement and management

15 days before stocking, add 80cm of water, soak 10kg-15kg of tea seed cake in warm water for 24 hours per mu, then sprinkle it all over the pond to kill wild fish eggs. Apply 100kg-150kg of fermented organic fertilizer per mu, and when the pond water turns yellow-green or tea-brown, you can prepare to stock the fry.

By mid-May, when the water temperature reaches 20℃, 2,500 fry of 2.5cm-3cm desalinated silver carp are stocked per mu. The fry are purchased from Xiamen and first placed in temporary ponds for cultivation. 200 fry of 5cm-6cm and 4,000 1.5cm desalinated tiger prawn fry are mixed and directly placed in the pond. When the fry are released, the pond water is tea brown, rich in natural bait organisms, with a transparency of 30cm and a salinity of 80‰.

The fry of the standard coarse pomfret are aerated and oxygenated in the temporary holding pond for 24 hours. Two days after the fry are put in, they are fed with zooplankton or newly hatched Artemia nauplii. One week later, minced fish paste is added with 30% powdered eel compound feed, mixed and kneaded into small balls, and put into the feed nets. Six to eight feed nets are placed in each temporary holding pond. The fish are fed 2 to 3 times a day, and the daily feeding amount is 1000g to 1500g per 10,000 fry.

Gradually acclimate to the 0# complete feed for silver pomfret. After 20 days of cultivation, the egg-shaped silver pomfret grows to 4cm-5cm, and the temporary holding pond can be opened to allow the fish to enter the large pond.

4. Breeding management

Feeding management. Pomfret is fed with puffed pellet feed specially made for golden pomfret with a crude protein content of 43%. Mullet and tiger prawns are not fed separately. Different types of feed are selected according to the size of the fish. Use 0# and 1# feed in the early stage, and 2# and 3# feed in the middle and late stages. The amount of feed should be adjusted flexibly according to the climate and water quality. Generally, less feed is fed on cold and rainy days, and more feed is fed on sunny days with high temperature.

When the water temperature is around 20℃, feed twice a day, and the daily feed amount is 8%-10% of the fish's body weight. When the water temperature is 25℃-35℃ from June to September, golden pomfret has a vigorous appetite and grows fast, so feed 3-4 times a day, and the daily feed amount increases to more than 15% of the fish's body weight. In hot and humid weather, control the feed amount appropriately to prevent golden pomfret from overeating.

Daily management. Daily management requires at least three inspections in the morning, afternoon and evening to observe the feeding situation of the pomfret. If the feeding amount of the pomfret is abnormal or the fish are dead, the cause should be found and the symptomatic treatment should be carried out in time. Frequently check the filter screens at the inlet and outlet, remove debris, and replace them in time if they are damaged. Pay attention to the changes in water quality and add new water in time if the pond water deteriorates.

Additional information

Body shape and habits: The body shape is similar to that of piranhas. It is about 20 cm long. Its whole body is silvery white. During the estrus period, the fins from the lower jaw to the abdomen, buttocks and the first few rays of the anal fin are all red. The silver pomfret is gentle and will not attack other fish. It can be raised with other large fish.

They like slightly acidic soft water and are not demanding in living conditions. They are omnivorous and love to eat aquatic plants. It is not advisable to plant grass in the water tank, otherwise it will be eaten up. They also eat animal bait. They love to swim in groups, are strong and easy to raise.
