Technology for raising soft-shelled turtle in spring greenhouse

Spring is not only the turning season of climate changes, but also the beginning of a new breeding cycle for soft-shelled turtles. Therefore, the management of spring turtles in plastic greenhouses is particularly important in the spring. Spring management technical work mainly has the following aspects:

First, the maintenance of plastic greenhouses

In the spring, the temperature is not stable, and plastic greenhouses must be inspected frequently. Repairs must be made to the damaged parts in time, and attention should be paid to the stability of the joints in the joints.

Second, the cultivation of young

It is necessary to select juvenile and young cubs in a timely manner and keep them in large-, medium-, and small-sized ponds in order to avoid biting each other. At the same time, the pools of juvenile and juveniles were combined and the pool water was completely replaced to remove dirt from the bottom of the pool.

Third, adult breeding

In April, the bottom soil of Chengyu will be cleared, new sand or soft mud will be added, and then disinfected. Disinfection should be performed using clear lime dry ponds, leaving the pool water to 5-10 cm deep. The amount of lime used is 60-75 kg. After the slurry is poured into the whole pond, it is best to use the muddy edge to splash the edge. When the medicinal property disappears after 7 days, the young turtle is released.

Before the stocking, pups should be sterilized by drug dipping. The 2.5% concentration of salt solution should be used. Dip at the water temperature of 10-32°C for 10-20 minutes to kill the body's parasitic bell-shaped worms, worms, leeches, etc. . The water temperature for stocking needs to be stable at 20°C or more, time in the middle or late April or early May, and the stocking density should be 6-8 pups/m2, which can reduce the number of intermediate points of stocking and minimize the growth of adult clams. interference. Freshly stocked oysters have poor appetite in one week's time, so the initial amount of artificial compound feed is 0.5-1% of body weight (in dry matter juice, different), and later with the elimination of sensation of tenseness, feeding The amount can be increased to 2% of the body weight, and it is fed once a day in the afternoon and in the afternoon, and it is performed according to the total feeding method. There are many feeding and management jobs for Orioles, but the main one is water quality management. In addition to maintaining the water temperature of 25-35°C, we should also look at the water color and transparency. The water color is green or dark green, and the transparency is the best in 20-30 cm. .

Fourth, the pro-management

When the temperature and water temperature both rise to about 20°C, it is necessary to feed on the relatives who recover from hibernation and try to use fresh fish that can easily digest and eat, and shellfish snails. After the resuscitation of New Zealand's hibernation, the application of lime once every 10-15 days (10-15 grams per cubic meter of water) can increase the calcium in the water, disinfect the water, prevent disease and control water quality, and maintain the transparency of the pool water at 30. Centimeters or so.

In warmer climates, intimacy will start spawning in late May. Therefore, the weeds in the spawning grounds should be eradicated as early as possible in late spring, the sand table of the spawning ground should be trimmed and loosened, the new river sand should be added, and the inspection and maintenance of the surrounding environmental conditions should be completed.
