In recent years, due to the rapid development of the soft-shelled turtle culture in the greenhouse, the production of soft-shelled turtles has increased significantly, and the price of commercial fish has started to decline, from about 400 yuan per kilogram in 1995 to about 100 yuan per kilogram. Such a low price of soft-shelled turtles makes the soft-shelled turtle breeding a meager and even loss-making, especially in the soft-shelled turtle breeding, so how to reduce the cost of farming in many ways to improve economic efficiency, has become an important issue in the greenhouse turtle breeding. First, rely on scientific and technological progress in ecological farming. Currently, there are few high-level professional technicians in the turtle farms. Ordinary operatives at some old turtle farms or people who have spent several days at a breeding school can become technical staff at the new turtle farm. It can be seen that the soft-shelled turtle farms do not attach much importance to the breeding techniques. Some soft-shelled turtle farms do not even have technicians at all and they have problems and find them again. Because these so-called technicians lack the basic knowledge of aquaculture, they simply do not know how to breed scientifically and the cost of aquaculture is greatly increased. Therefore, turtle farms must have high-level professional and technical personnel for scientific ecological farming. Second, careful selection of land, save construction. This is important for new or expanded turtle farms. Some people have their eyes fixed on the land rent when setting up a site for construction, and where they are cheap to build, regardless of the farming conditions. As a result, the leakage of the pool and the acidity of the water were discovered after the construction of the site. This resulted in a corresponding increase in the costs of water, electricity, coal, and labor, which increased the cost of cultivation. Therefore, it is necessary to select sites for construction under the guidance of professional and technical personnel. In addition, when the infrastructure is built, it is necessary to save money as much as possible in the case of meeting the culture conditions. Third, the two methods can effectively save the cost of purchasing baby toys, buy eggs, and hatch themselves. This method can reduce the seed cost by about one-third compared with the purchase. However, it must be noted that professional and technical personnel must select quail eggs to ensure the fertilization rate. Incubation must also be performed by professional and technical personnel to ensure a high hatching rate. In addition, the self-incubated juveniles have a fast adaptability to the environment of the soft-shelled turtle farms, and have low incidence and high survival rate, which will reduce the cost of the rearing culture accordingly. 2, in the spring to buy wild female turtles for raising, wait until the turtles finished after the sale of turtles. This method is more suitable for turtle turtles in areas where there are more wild turtles, or where turtles require more than 10,000 turtles, which can reduce the cost of seedlings by more than half. But pay attention to: (1) to ensure the quality of turtles during the acquisition. (2) Female turtles do not receive male turtles because they have mated with male turtles and stored sperm at the end of the previous year. (3) It must be purchased at the price of the commodity or slightly higher than the price of the commodity. The seeds obtained by this method are wild and can be sold at the price of wild turtles after cultivation, which increases the output value and indirectly reduces the cost of breeding. Fourth, according to local conditions, with fresh live feeds into self-mixed feedstuffs accounted for more than 30% of the total cost of turtle breeding, is the main input of turtle farming, so take measures on feed, can significantly reduce the cost of farming. 1. When using full-price compound feed, it can be adapted to local conditions, with some fresh live food. If there are livestock and poultry farms near the turtle fishery, they can be mixed with livestock and poultry (liver, lung, intestine). In areas with numerous rivers and lakes, fish, shrimp, snails, oysters, etc. can be fed. In addition, turtle farms can also cultivate their own live bait, such as: leeches, clams, chironomid larvae, mealworms, fly maggots, snails, etc. These are very promising live baits. With live bait, the cost of feed can generally be reduced by 10% to 30% due to the difference in quantity and area. 2, larger turtle farms can be formulated according to feed. At present, the price of turtles' full-price compound feed is relatively high, generally around one million yuan. Fish meal accounts for about 60% of the feed, which is the highest price of the feed's main ingredients. The best fishmeal is about 6,000 yuan per ton. The profit of the whole-price feed for turtles is high. Moreover, the quality of the whole-price mixed feed of the soft-shelled turtle is not stable. In the feeds that the author used, even the feed of the same brand, there is a difference between each batch. Therefore, it's better to have a self-provisioned feed and be aware of it, and it can reduce costs. Self-made feeds are suitable for larger turtle farms and must be conducted under the guidance of technicians. When you feed your own feed, you must not cut corners and must meet the nutrient needs of the turtle's growth. In addition to the depreciation of labor and feed, self-provisioned feed can save more than 30% of feed costs. The above-mentioned two methods can also be adopted at the same time. That is to say, using their own fodder to match with the live bait they cultivate, the cost of feed can be made cheaper. At the same time, live bait can increase the survival rate of turtles, improve meat quality, and increase the price of commercial turtles. V. Prevent and treat diseases. Disease prevention is the main reason. Scientific drugs must be used during the turtle breeding process. It directly affects the survival rate of soft-shelled turtles. Must be mainly to prevent disease, because once the turtle is sick again medication, can only control the spread of the disease and cure milder turtles, for those who have a serious illness of the turtle has no effect. Therefore, we must prevent disease and focus on prevention work regularly to reduce the incidence rate and increase the survival rate. The use of drugs must be scientific and reasonable and must not be abused. Some turtle farms use drugs every day, so that turtles live in medicine, making bacteria produce serious drug resistance, increasing the amount of drugs, the cost increases. Excessive drug use also reduced the quality of the soft-shelled turtle and reduced the price of the product. Scientific choices should be made in the varieties used. At present, there are many varieties of commercial fish medicines on the market that have a certain effect on the turtle disease, but the price is relatively high. The author believes that the use of high-priced commercial fish medicines should be based on common cheap drugs. Among them, Chinese herbal medicine has no side effects, and there is no residue in the turtle body, which will not affect the quality of the turtle. It is the future direction of development. Sixth, scientific management, many aspects of conservation. Saving costs must be carried out in many aspects, and scientific methods should be used to start from scratch. In terms of water, coal and electricity, water quality control agents such as photosynthetic bacteria and EM should be used to control the water quality so that the turtle farms can reduce the amount of water exchanged, thereby reducing heat loss, reducing the amount of coal consumed, and reducing electricity consumption. In addition, greenhouses must use double-layer membranes. Compared with single-layer membranes, double-layer membranes can save more than half of coal by artificial means. This is an important part of turtle farms. However, the use of humans must be streamlined and often lived in, so that problems can be solved in time. , reduce losses. In general, the soft-shelled turtle farms must be carefully planned and saved. Seven, look at the market, high out of the pond. In recent years, the price of soft-shelled turtles has changed quite sharply, and prices have also been different in the same year. Therefore, we must fully understand the market, seize the opportunity, and exit the pond at a relatively high price.
