Countermeasures for breeding soft-shelled turtle in outer pond in high temperature season

In the process of ecological soft-shelled turtle culture in the outer pond, the high temperature season is the key stage, during the high temperature period, the feeding amount of the soft-shelled turtle is large, and the growth rate is fast, but it is also the peak period of disease outbreak. if it is not well managed, it will cause significant economic losses to the farmers, so if and do a good job in the management of the high temperature season will be directly related to the farmers' harvest in a year.

With the coming of summer, the temperature rises, the feed amount of soft-shelled turtle is large, and the metabolism is exuberant, the metabolites and residual feed in the water are easy to cause changes in water quality, and the harmful substances such as ammonia nitrogen and nitrite in the water are easy to exceed the standard. in addition to daily regular disinfection, farmers often ignore the conditioning of water quality, and only by constantly adjusting water quality can we maintain the balance of water quality factors. Especially in high temperature weather, water quality conditioning, bottom quality improvement is particularly important, so it is recommended that farmers transfer water regularly, preferably once every 15 days, water quality conditioning generally uses micro-ecological agents, such as dental bacillus, E-M bacteria, yeast, etc., when using ecological agents, generally sprinkle them on a sunny day at 8 ~ 9 o'clock in the morning, add water and activate for 1 hour or 2 hours, and turn on the aerator one hour in advance. The use of ecological preparation 3Mel can not disinfect and kill insects within 5 days. Conventional disinfection uses pollution-free and residue-free drugs such as amino acid iodine and chlorine dioxide to reduce the concentration of bacteria and inhibit the infection of soft-shelled turtle. In high temperature from July to September, the soft-shelled turtle has strong activity and large food intake, and it is necessary to maintain a reasonable water depth of 80cm. In general, the water depth of 80cm should be increased in muggy or rainy weather to ensure the fluidity of the water surface and provide sufficient dissolved oxygen. In addition, farmers should control the amount of feed according to the situation of the soft-shelled turtle, so as to avoid excessive feeding to corrupt the water. In general, the adult stage of soft-shelled turtles should be controlled at about 3% of their body weight. At the same time, it is suggested that health products such as protecting liver and stomach and multi-dimensional should be added to the feed, which has a good effect on enhancing the immunity and disease resistance of soft-shelled turtle. In the high temperature season, the white floor is a disease easily caused by the culture of soft-shelled turtle in the outer pond. The disease is harmful, the mortality rate is high, the body of the diseased turtle expresses the floor, the anatomy shows that the local intestinal tract has necrotic symptoms, the intestine is empty and white, and the liver is congested or purple-black. Can refer to the following prescription treatment: 1, the disease pool with chlorine dioxide to treat twice the amount of continuous spill for 3 days. 2. Take Chinese and western medicine internally, use amoxicillin + gentamicin 50% each, add 1% of daily dry feed, and add 50% of heparin + Buxue granule to 2% of daily dry feed for a week.
