Most of the turtles like to dive underwater, drill into the mud, or go ashore to dry their hands and activities, leaving a large amount of space for the turtle pool to be idle. Based on this situation, we carried out a trial last year, that is, 8 pools, conventionally raising turtles, 2 turtles, and 6 pond turtles. As a result, turtles in the polyculture pond weighed more than 100 grams on average compared to the single turtles. In the breeding process, the tortoise fishes were basically free of disease, turtle feed was reduced by more than 30%, and the cost of raising turtles was greatly reduced. The economic benefits were improved. 2 times more. Therefore, polyculture of turtle fish snails is an effective way to increase water use efficiency and increase farmers' income.
I. Disinfection in the clear pond Before turtle turtle snails are put into use, the rearing pond must be completely disinfected. The method is to throw 500 kg of quick lime per acre into the pond and restock it after about one week.
Second, pond construction Aquaculture ponds should be designed and constructed in strict accordance with the requirements of the turtle ponds, mainly turtles, fish snails and turtles as the supplement. Juvenile turtle pool should not be fish, but can raise snails, other turtle pool, as long as the water level can be poured to more than 1 meter can be mixed fish. General fish ponds can also be transformed into turtle fish polyculture pools. However, because turtles have the habit of climbing walls to escape holes, they should build escape prevention walls around the pond before they can breed turtles. They also need to build foods as needed. Terraces, rest areas and turtle spawning grounds.
Third, species selection turtles to colorful turtles, yellow-throated turtles, tortoises as well, Snapping turtles, eagle turtle turtles should not live in groups, killing each other habits, money turtle, gold turtle, Yunnan shellfish expensive, and Not easy to distinguish, the first raisers are easily fooled. General warm-water non-meat fish can be used as polyculture fish such as squid, which can make full use of the plankton in the water. Snails are best used for snails. This snail breeds quickly, like to eat turtle manure and organic debris, and the loach can be caught in the wild in rice field ditches. It prefers weeds and parasites in the pond and is a bottom cleaner. At the same time, young larvae are the best food for turtles.
Fourth, the polyculture density turtle pool can be stocked about 5 cm of small size fish species used to cultivate large-size species. Adult turtle ponds and turtle pools are stocked with large-sized fingerlings about 15 cm long to develop commercial fish. Density for the fish per acre of water by conventional amount or reduce some, snail is 25 kg per 100 square meters, loach about 5 kg per 100 square meters, let it breed, young turtles 4-6 per square meter, adult turtle 2 - 4 only.
V. General management Turtle fish snail polyculture management, in principle, is divided and ruled. Among them, fish rearing and management are the same as those for pond fish farming. Ponds for polyculture of turtles and fish should properly feed some fish feeds, such as melons and fruits, in water. By raising some plants such as water lilies, you can purify the water, feed the snails, and shave them, creating a good environment for the fish. The polyculture of turtle-fish snails plays an ecologically balanced role in the growth of turtle fish. At the same time, the larvae of the snails that are bred by snails are also the best food for the turtles, which accelerates the growth of the turtles and increases the number of eggs laid by the turtles. The water quality of the pool is good, the amount of water exchanged is small, and it is almost disease-free all year round. However, when the climate is abnormal (especially in hot weather), as the water body is convected up and down, and the bottom layer is turned over, the amount of dissolved oxygen is reduced, causing discomfort to turtles and reducing the amount of activity. The fish will have a floating head phenomenon, which can cause flooding in severe cases. death. In order to prevent accidents, farmers should add new water in time when the climate is abnormal. Usually, the farmers should top up the fertilizer in small quantities, maintain the appropriate body fat, pay attention to not less, and maintain the cleanliness of the water body. We must also step up the inspection of the ponds, guard against enemy enemies, prevent escape, and guard against theft, observe the turtle snails' activities, find problems, and deal with them in time. In addition, during the pro-spawning and spawning season, the number of pulls should be minimized so as not to affect the mating and spawning, reduce the amount of eggs laid, and cause economic losses to the turtles.
