The whole body of squid is a treasure. The meat has no intermuscular puncture, and has a high consumption rate. It can be used as raw fish and fried fish fillets. It can also be smoked and canned. The kisses, fins, liver, iliac crest, bone, tail bowel, and notochord are all The finest cuisine, especially the "caviar sauce" made by the processing of spatula eggs, is a world-renowned nutrient food. Its kisses, bones, and skins can be made into glue, and the skin can also be made into high quality leather. According to another report, the anti-cancer factors contained in salmon are 10 to 15 times that of sharks. Long-term use of squid has special effects on cancer prevention, cancer prevention, stomach pain prevention and hair loss. In recent years, the artificial breeding of eel has gradually emerged, and people in the aquaculture industry are optimistic about its breeding prospects, thinking that it will become a new hot spot for optimization of aquaculture species. The carp is large in size and has a long life span. It has a high survival rate, a rapid growth rate, a high genetic plasticity, and a strong resistance to disease. It is easy for domestication. Under artificial breeding conditions, when the nursery is raised to the end of the year, individual weight can reach 0.7 kg to 1 kg, 2 instars to 2 kg to 3 kg, and 3 instars to 5 kg. There are many species of squid and they have been successfully tested and cultivated. Artificial breeding has passed and there are batches of saplings to be served including small-bodied oysters, paddlefishes, schistosomiasis, Siberian quail, and hybrid crickets. Its commercial farming has static water, running water and other farming methods. However, it has not been widely promoted. Therefore, the number of eel products is very limited, the market price remains high, fresh fish 200 yuan / kg to 250 yuan / kg, caviar 3,000 yuan / kg to 4,000 yuan / kg. The current rapid development of commercial squid as a high-yield and high-efficiency technology is described as follows: 1. Rapid development of hydrostatic water 1. Pond selection Ponds cover an area of ​​1,300 square meters, with a water depth of 1.5 to 2 meters. Water sources are preferably reservoirs, rivers and lakes. Water quality should be clean and free of pollution, and equipped with aerators. The pond is disinfected with quicklime clearing pool about a week before stocking. Note that bleaching powder should not be used to disinfect, because the growth of the catfish should avoid bleaching powder. 2. Quickly grow seedlings with standing water and raise the seedlings whose stocking length is less than 15 cm. 500 to 700 fishes per 667 square meters, with stocking squid and squid summer flowers of about 4,000. The seedlings should be soaked with 3% saline for 20 minutes before stocking. 3. The feedstuffs should be installed in the feed ponds. According to the characteristics of carp, especially in the deepest part of the ponds in the summer, the feed stand should be set at a depth of not less than 2 meters, and 1 to 2 points per 667 square meters. Department. Special non-mixed and compounded diets were fed. Crude protein was greater than 35%. Feeding was performed 3 times during the day (at 6 o'clock, 13 o'clock and 16 o'clock). At 13:00 at night, the feed amount was 2.5% to 4% of the smoked fish weight. 4. Daily management The pond should be changed frequently so that the transparency of the water is greater than 40 cm. When the pond's water temperature rises to 28°C, the fish will stop feeding. During this period, it is necessary to increase the supply of fresh water day and night, stop feeding, and start the aerator at noon on a sunny day. Second, the rapid development of water 1. To build pool ranging from 50 square meters to 100 square meters, round, square and rectangular can have a variety of water supply and drainage systems. In order to save water, each pool can be built into a ladder shape with a depth of 1.5 meters and a water depth of 80 cm to 100 cm. The pool roof is equipped with a steel shed, which can be installed with a shed film and a screen covering. The water source should be sufficient, the water quality should be fresh, non-polluting, the dissolved oxygen should be high, and the water temperature should be lower. The bottom of the reservoir can be immersed, and the underground spring water is used for aeration. 2. It is advisable to plant 30 to 40 tailed carp species with a stocking length of 15 or more per square meter. The specific stocking density depends on the conditions of the flow exchange, etc., and gradually reduces the density for a long time as the pool grows. 3. Feeding water Quickly develop bait feed special feed for squid, and it is better to have a pellet feed. The particle size of the bait differs depending on the size of the individual fish, and the protein content is required to be higher than 40%. The fish oil content is appropriately increased, vitamins are added, and the nutritional balance is maintained. The number of feedings is 4 to 6 times, and the feeding rate is about 3%. Feed around the pool wall, reducing water flow when feeding. 4. It is advisable to change the water flow rate of the water in order to replace a pool of water within 1 hour to 1.5 hours. Pay attention to water quality and water temperature regulation to ensure high dissolved oxygen. In general, it takes 2 to 3 clearings per week to clear the pond. Every time the sewage is drained, about 1/2 of the water is drained. The edge of the row is cleaned, and the waste in the pool is exhausted completely. In summer, the temperature is high, the shade net is placed on the shed, and the amount of water exchange is increased. Divert sewage to ensure that the water temperature is below 30°C. In the winter pool, special black membranes for aquatic products are used to protect the pool from frost and reduce the number of sewage discharges. Third, carp disease prevention and treatment of carp body plate, less natural enemies, artificial breeding history is short, its epidemic, fulminant disease is still rare. The existing reports on the deterioration of multi-dimensional water quality, but still should do a good job of water quality control, adhere to the prevention of disease prevention work: First, the culture pond before the use of conventional clear pond; bait when the process of regular use of special disinfectants to eradicate the bacteria Third, in the compound feed regular sky furan sulfoxide or norfloxacin made baits to prevent enteritis disease; Fourth, during the winter, we must do everything possible to raise the water temperature, so as to avoid the emergence of white fish and the occurrence of mycosis. In the case of trichodiasis, oral filariasis and tongue cup disease, potassium permanganate 2 mg/m2 or copper sulfate 75 mg/m2 can be used for prevention and treatment.
