Is it difficult? how much can you buy per jin on the market? How do you raise it? How old can you grow up? It is reported that pearl soft-shelled turtle is a new variety introduced from the United States in recent years, which is mainly characterized by fast growth and high market price. In greenhouse culture, the weight gain of male turtles is slower, and the annual weight gain of female turtles is 1500kg to 2500kg. The price of this soft-shelled turtle is 600.70 yuan / 500g in Guangzhou market. The soft-shelled turtle (Trionyx sinensis) is a national second-class protected animal, and its reproduction rate is worse than that of the Chinese soft-shelled turtle, but it grows faster and the market price is higher. In recent years, the commodity price of the soft-shelled turtle is stable at about 170 yuan / 500 grams. However, the seedlings are more expensive and need a culture license for breeding.

How to raise pearl turtles?

1. It is not difficult to raise pearl soft-shelled turtles. The skin of the soft-shelled turtles can subsidize breathing, which allows them to stay underwater for a long time. They are highly aquatic turtles, so there is no need to set up floating islands in the feeding tank. The water temperature should be controlled between 24 and 28 degrees in winter. Pearl soft-shelled turtles are pure carnivores. Very small larvae can be fed with red nematodes, while larger ones can be fed with small fish, shrimp or lean meat. They rarely have the habit of drying their shells, and they should avoid direct sunlight in their breeding.

2. Greenhouse conditions

A simple greenhouse for conventional culture of soft-shelled turtle covers an area of 405 square meters, including 12 culture ponds, each with 30 square meters, a total of 360 square meters, with a depth of 60 centimeters. The water source is sufficient, the water intake is convenient, the water quality is fresh and there is no pollution source nearby. A 1-inch oxygen pump, each tank is equipped with 10 inflatable heads.

3. Greenhouse cleaning and disinfection

Before the test, the greenhouse hot water pipe, oxygen pipe, inflator and other facilities were repaired and replaced, the cement pool was cleaned and disinfected, the greenhouse walls and hallways were also disinfected, and the disinfection drug was trichloroisocyanuric acid.

4. Soft-shelled turtle seed stocking

1400 American soft-shelled turtles with an average specification of 10g were purchased on September 13, 2004. they were divided into 4 ponds and stocked in each pond. Disinfect the soft-shelled turtle with seed essence before stocking. When stocking, the water level in the pond is 10 cm. Put the sterilized juvenile soft-shelled turtle on the edge of the pool and let it climb into the water by itself.

5. Feeding and management

⑴ temperature Control: how to raise Pearl soft-shelled Turtle? During the whole culture period, the water temperature was controlled at 3031 ℃ and the air temperature was controlled at 32 ℃.

⑵ feed: how to raise pearl soft-shelled turtle? The juvenile soft-shelled turtle feed with 46% protein content was fed throughout the culture period, and the feed was made into soft particles with a particle size of 3 mm at the beginning and 6 mm at the later stage of growth. Feeding under water, the table is placed flat on 10 cm below the surface of the water, and the table is made of wood. Bait 3 times a day, each eating time is controlled within 15 minutes.

⑶ water quality management: according to the change of water quality, the sewage is usually discharged once every 2 days, each time 2 cm, and then injected with new water. With the growth of soft-shelled turtle, the water level was gradually deepened, and the highest water level was increased to 40 cm after 2 months of culture.

⑷ disease control: disease prevention and control should give priority to prevention. Sprinkle 20 g / m 3 quicklime and 0.2 g / m 3 trichloroisocyanuric acid alternately in the whole pool every half month. Death was caused by bacterial infection due to improper operation of the pond. After feeding enrofloxacin and oxytetracycline to disinfect the water, the disease was basically controlled.

How big can the pearl turtle grow?

In general, the maximum of constant temperature culture can be more than 10 jin in two years, and there is a great difference in the growth rate between male and female. They are sexually mature in 4-5 years, each can lay 16-28 eggs each time, and the oviposition period is 75 days.
