CATDOLL : CATDOLL: Breeding pufferfish (pufferfish breeding network)

1. Breeding pufferfish

Your first question My answer The survival temperature of pufferfish is 8-36℃, and the optimal growth temperature is 20-28℃. When the water temperature drops to 15℃, the pufferfish needs to be transferred to the greenhouse for continued breeding or wintering.

Your second question, my answer: my country's pufferfish farming is generally in the East China region. There are 3 large breeding bases and 24 small ones. The price varies greatly depending on the size of the fry you want. The price changes every year. Generally, the price of fry is around 1.6 yuan. The red-finned Oriental pufferfish is the best and has the highest price. There was a time when it was out of stock.

My answer to your third question is that the sales in East China are generally in Asia, and in Guangdong, Hong Kong and Zhuhai in China. Japan has the largest demand in Asia. The Japanese side has signed a contract with Zhonghui Fishery in Liuzan Town, Luannan County, Hebei Province. Until now, the export specification requirement is 600 grams. One catty is about 30 yuan. The lowest price is more than 20 yuan. The price is still rising.

Pufferfish is a rare aquatic product. In recent years, due to the pollution of the Yangtze River and people's indiscriminate fishing, the number of naturally grown pufferfish has become less and less, and the market price has been rising. It has development prospects, but the economic investment is relatively large.

Basic characteristics: pufferfish are migratory fish and can be bred in pure fresh water. They are omnivorous and mainly feed on animal bait. Under artificial breeding conditions, they can be domesticated to eat artificial compound feed (such as eel feed). The survival temperature of pufferfish is 8-36℃, and the optimal growth temperature is 20-28℃. When the water temperature drops to 15℃, the pufferfish needs to be transferred to the greenhouse for continued breeding or wintering. Pufferfish have high requirements for dissolved oxygen, which should be greater than 4 mg/L. Pufferfish can be cultured in ponds. The pond area should be 1-4 mu, the water depth should be 1.5-2 meters, the silt should be less than 10 cm, the water transparency should be 30-40 cm, and each pond should be equipped with an aerator; the seedlings should be released in mid-to-late June, with 2,500 5 cm seedlings per mu, and the seedlings will reach 10-15 cm in size by early September. They should be separated and raised in time, with 600-800 per mu. There is no special feed for pufferfish, but eel feed can be used instead. It usually takes 30 months for pufferfish to grow from seedlings to market size.

2. How to raise pufferfish

Pufferfish is a kind of fish that lives in the seawater and lives in the Yangtze River. It is named as such because it makes pig-like squealing sounds when it is caught in the water. Pufferfish is a very interesting fish species with two forms. It is no different from ordinary fish in daily life, with a long body. However, once it is attacked or angry, it will inflate its body into a small ball with small thorns on the surface to protect itself and scare off the enemy. It feels a bit like the Hulk, doesn't it? However, many people think that the inflated pufferfish adds a bit of cuteness. Are you trying to kill your enemies with cuteness?

Pufferfish are widely distributed in my country, including along the coast of my country, as well as in the Yangtze River, Pearl River and other places. Pufferfish are a fish with the habit of migratory migration, so every year they return from the sea to the confluence of salt and fresh water in the coast to lay eggs. There are more than 30 species of pufferfish distributed in my country, among which the dark-skinned Oriental pufferfish lives in the middle and lower reaches of the Yangtze River all year round. Because of its delicious meat, it is known as one of the "Three Fresh Foods of the Yangtze River".

Pufferfish are omnivorous fish species, generally feeding on fish, shrimp, crabs, shellfish, insect larvae, cladocerans, copepods, and leaves and filamentous algae of higher plants. Ming-type pufferfish generally eat very little during their reproductive migration.

As we mentioned above, pufferfish is poisonous, so it is generally not recommended to be used in ancient books. However, because the meat of pufferfish is so delicious, many people are willing to risk their lives to try it. There are records of eating pufferfish in Japan and China from ancient times to the present, and many people have died from pufferfish toxins. Therefore, it is generally impossible to cook a good pufferfish without decades of effort.

The main toxins of pufferfish are distributed in the reproductive glands and internal organs. It takes a chef with excellent knife skills to remove these parts without breaking any of them. However, in recent years, with the intervention of artificial breeding technology, the toxins of pufferfish have been greatly controlled and will not cause fatal dangers. So how is artificial breeding of pufferfish operated?

The first thing to pay attention to when raising pufferfish is the temperature. Generally, the suitable growth temperature for pufferfish is above 15 degrees and around 12 degrees. The feeding ability of pufferfish decreases, and they basically stop eating below 10 degrees. Therefore, it is necessary to do a good job of wintering for pufferfish, especially to keep the water clear and the oxygen content in the water, and to properly add oxygen to the water.

The pond should have a heating system. When the temperature is below 12 degrees, manual intervention should be made to raise the temperature to around 14 degrees. Secondly, attention should be paid to the density of fish species. Too dense a population may cause pufferfish to kill each other, resulting in a lower survival rate. Finally, disease prevention and control can be achieved by adding appropriate drugs for disinfection.

3. Where can I buy pufferfish? How much is one? Can I keep it alive?

For about ten yuan, I bought two green and patterned ones. They said they were very interesting submarines, and they ate small shrimps. You need to add some salt when changing the water.
