How to breed soft-shelled turtle? Six main points of soft-shelled turtle culture

Soft-shelled turtle is a common species in aquaculture. Soft-shelled turtle is also called soft-shelled turtle, which is distributed in lakes, reservoirs and wild ponds in most parts of China. The following editor will introduce the six main points of soft-shelled turtle culture to help you raise soft-shelled turtle.

1. Adjust the aquaculture water.

The indexes of turtle water are usually adjusted as follows: dissolved oxygen is more than 5, pH value is between 7.5 and 8, alkalinity and hardness are stable at 3.0mg / L, ammonia nitrogen content is less than 0.02mg / L, nitrite concentration is less than 0.1mg / L, and the transparency of pond water is between 25cm and 30cm.

2. Timely discharge, scientific change of water, and regular discharge of bottom organic matter according to water color.

3. Divide the pond reasonably, clear the pond in time, raise the soft-shelled turtle by grade, and adjust the culture density.

In the process of healthy culture, the specifications of soft-shelled turtle fry in the same pond should be consistent as far as possible, which can avoid biting, great disparity in growth and affect the overall growth effect. At the same time, reasonable separation and cultivation is also conducive to management, and it is easy to grasp the implementation and improvement of the feeding scheme.

4. feed high quality feed to improve the conversion rate of bait and reduce the pollution of residual bait and feces.

In addition, for all kinds of specifications and all levels of culture ponds, production files should be established separately, and records must be made for the hydrochemical factors, feeding conditions, epidemic occurrence and prevention in each pond, as well as the specifications and quantity of soft-shelled turtles in each pond, so that technicians can refer to them and serve as the basis for formulating production plans and technical measures to be taken in the next stage.

5. regular prevention, proper control of the number of phytoplankton and plants, and effective regulation of water quality.

In the process of production, Chinese herbal preparations (such as Shidu Shuangke, Sanhuang Powder, Gandankang, etc.), antimicrobials (such as Bdellovibrio, marine actinomycetes, etc.) and anti-stress preparations (such as Vc powder, immune polysaccharides, electrolytic multi-dimensional, etc.) were regularly added to the diet. At the same time, preventive measures such as regular disinfection of pool water and sprinkling stress-reducing drugs (such as high anti-stress drugs,) during pond separation and cultivation, and regular use of sediment and water quality improvers (such as biological bottom improvement 91, double-effect pool bottom purification, etc.) to improve pool bottom quality and water quality must be carried out strictly according to the production plan.

In daily management, spot check the growth status of each pool in time. According to the eating situation to determine whether the disease occurs in the group, once the diseased soft-shelled turtle is found, immediately remove the isolation, diagnose the disease, and treat it in time. And carry on medicine bath or drug prevention to the whole pool to prevent the occurrence of infectious diseases. In case of sudden change of weather, rainstorm and water change, stress-reducing drugs (such as Vc powder, oligosaccharide +, etc.) should be used in time to reduce the stress response of soft-shelled turtle.

6. Feed use control.

The selected soft-shelled turtle feed should first comply with the relevant provisions of the Aquatic Industry Standard of the people's Republic of China-Chinese soft-shelled Turtle compound Feed (SC/T1047-2001). Feed should also be properly preserved, and the environment of the general farm is relatively humid, so it is necessary to keep the feed room cool, ventilated and dry. Pay attention to the freshness of the feed and use the prepared feed as soon as possible. Check the feed before each feeding, and it is strictly forbidden to use moldy or spoiled feed. The feeding of feed should be scientific and standardized. In addition to adhering to the principle of "four fixed time, quantitative, fixed point, fixed quality", the feeding amount should be adjusted according to the eating situation of soft-shelled turtle, and the feeding rate should be lower than its full level (eight points full) as far as possible. In order to achieve the purpose of improving culture efficiency and maintaining good water quality.

In addition, in order to increase the nutritional value of feed, improve digestibility, reduce excretion, and then improve the quality of soft-shelled turtle accordingly, we usually use powdered formula feed at present. This kind of feed is generally made into soft pellet feed by adding water and oil before feeding, which has soft texture and good palatability.

As the physiological and nutritional requirements of soft-shelled turtle are different in different growth stages, it is very important to choose the feed formula of the corresponding stage. Juvenile soft-shelled turtle, juvenile soft-shelled turtle and adult soft-shelled turtle feed should not be misused or mixed, otherwise the feed will be wasted and the cost will increase. it may even cause nutritional diseases of the soft-shelled turtle.

Soft-shelled turtle culture should not only do a good job in feeding and management, but also do a good job in disease prevention and control in order to obtain higher culture benefits.
