First, the main advantages
1, improve the utilization of water. Under the circumstances that the prices of aquaculture products have fallen and the market competition is fierce, raising the water body recultivation index and fully tapping the potential for water production is a feasible model for aquaculture structure adjustment.
2, increase production and efficiency. Carp breeding mainly uses the wild fish and shrimp as the bait in the main pond to fight for food, fight oxygen, and compete for space in the main breeding pond, which is conducive to the improvement of the yield and quality of the main breeding breeds. Increase revenue by several hundred dollars.
3, less investment, low risk. Raising squid in the water surface of cultivating eating fish and broodstock has better environmental conditions, no need to increase supporting facilities for breeding, and only a small amount of cost is required for the investment of squid seedlings. During the cultivation, attention should be paid to the aspects of dissolved oxygen, medication, etc. There is almost no risk of raising the squid.
Second, set the way
1, adult fish pond raising. Ponds for feeding fish are required to have sufficient water sources, good water quality, and easy injection and drainage. The area is 5 to 10 mu and the water depth is 2 to 25 meters. General mu nesting 1 instar carp or early summer carp 50-80 tail.
2, broodstock nesting. Bred broodstock with broodstock as its main broodstock, due to frequent flushing, the ecological conditions are more suitable for the growth of bonito. After the end of the artificial breeding, 5 to 8 centimeters of squid summer flowers are planted in 50 to 100 tails to increase income by about 15 kilograms.
3, large water surface raising. The use of water-sheltered forms of large-scale fish farming, low yield, large space for water, the most suitable set of mullet. In general, 25 to 30 tails of carp fingerlings or summer flowers can be used without affecting the yield of conventional cultured fish, and no additional feeding of bait is required.
4, small river ditch raising. Xiaohe Ditch has more wild fish in the middle of the river, and the water quality is superior. Sets of squid can effectively use the wild fish in the river ditch. Generally, about 30 larvae of large-sized bream fish can be stocked in an amount of 50 grams or more per acre.
Third, pay attention to matters
1, to maintain a high dissolved oxygen. Mackerel has a higher requirement for dissolved oxygen, and its suffocation point is 31 times that of carp, 51 times that of carp, and 125 times that of carp. Therefore, raising the water surface of squid requires fresh water and adequate dissolved oxygen. It is better to plant a certain amount of water plants. This will not only adsorb the organic matter in the water, but also reduce the water's fatness, which in turn can hide the squid. During the growing season, new water should be frequently refilled, and during the hot season, the water should be changed frequently. It would be better to maintain micro-flowing water.
2, to ensure adequate food. Carp is a ferocious fish. It uses small fish and shrimp as baits for life. It is extremely gluttonous and has similar phenomena of gluttony when it is insufficient or unpalatable. Therefore, before the eel stocks are stocked, the number of bait fish in the nesting pool should be investigated and analyzed. If the number of wild fish is small, the wild fish or home fish summer flowers should be introduced into the pool first. When feeding bait fish, consider the specifications of the bait fish and require bait fish to be 2/5-3/5 of the length of the pond carp.
3, use drugs with caution. Because squids are extremely sensitive to some commonly used drugs, such as trichlorfon, malachite green, methadone, chlorinated ketone, and mercurous nitrate, they should be prohibited or used with caution in salmon farming. The prevention and treatment of diseases on the water surface of squid can be implemented by thoroughly disinfecting the seedlings before stocking, creating a good living environment, regularly pouring low concentration lime solution, and using biological agents such as photosynthetic bacteria for ecological control.
The squid, also known as osmanthus fish, is the best-selling freshwater variety in the market. Practice has proved that single carp needs to be provided with sufficient food and fish, and the technical requirements are relatively high. It is difficult to carry out large-scale farming. For example, raising squid in other aquaculture water bodies can not only provide a large number of valuable fish for the market, but also increase aquaculture production and efficiency, and it is worth promoting.
