I. Pond conditions and preparation
1. Pond conditions require sufficient water sources, good water quality, convenient drainage and drainage, guaranteed power supply, and convenient land and water transportation. Each aquaculture pond area is generally 10 mu to 20 mu, and the water depth is 2m to 2.5m. It is best to support a small pond of 1 to 2 and 3 mu to facilitate the cultivation of fish species and fish stocks or adult fishes. The wall of the pond is required to be solid and non-leaking, which is more than 0.5 meters above the historical maximum level.
2. Supporting facilities A 3 to 5 ton hanging pulp boat is used to collect aquatic plants, transport fish species and adult fish into natural waters. Conditional installation of a 3-kilowatt aerator per 5 mu of water.
3. After the pond has cleared the winter and spring dry ponds, excavate too much silt in the trenches to keep the silt layer below 10 cm. It is best to freeze for 20 days. Before the stocking, 75 kg of lime and 25 kg of tea seed cake were dissolved and soaked in the whole pool after soaking. The basal fertilizer was applied after disinfection, and the water was filtered.
Second, breeding technology points
1. Seed rearing grass carp rearing weight of 500 grams, 250 grams and 25 grams of three specifications, acre put 150 to 750 or so; group head maggot rearing weight of 100 grams and 50 grams of two specifications, acres put 300 ~ 350 tails; squid, squid rearing weight of 150 grams, 100 grams and 25 grams of 3 specifications, acres of 1000 to 1200 tail, squid and squid ratio of 6 to 8:1; 50 years of heterotrophic silver pupa stocking and 25 grams of two specifications, about 1000 acres of acre; squid rearing 50 grams of fish species, acre put about 100.
2. Source and Distribution of Feed Sources The perennial alfalfa, clover and annual ryegrass, sudangrass, bitter leeks and other high-yield pasture varieties planted in pond margins are used. The planting time, rind management and management should be well connected to solve the early spring and late autumn green feeds. Shortage problem. From May, the boat can be used to collect natural fodder such as Vallisneria, Malania, duckweed and other green feeds, as well as terrestrial green feed, such as vegetable leaves, melon leaves, and tender vines. There are chicken manure, duck dung and pigs, cow dung, etc., and there are conditions to raise pigs and raise chickens at the side of fish ponds. Each year, aquifers require 26,000 kilograms of green feed (including 70% of aquatic plants and 30% of terrestrial grasses), 2700 kilograms of various manures (50% of the total weight of chickens and pig manure in terms of wet weight), and another need for cakes. Concentrates such as bran are 500 kg to 600 kg.
3. Fertilization and Feeding Basal fertilizer Generally, the manure is mixed with 200kg to 500kg of manure or mixed compost. It is best to spread it to the bottom of the pool, and use the rice dumpling to stir the fertilizer in the pool mud to maintain the fertilizer effect for a long time. Top dressing should be based on the season, water temperature, color and transparency.
Take a small amount of the principle of diligence, the fertilized material must be fermented. Adhere to timing, positioning, qualitative, quantitative feeding methods, green feed generally 2 to 3 pm feeding, eat before the evening. Fine bait is supplemented in this breeding mode, and it can be considered as a good apology for the natural food and green feed in the water, so that the fish can eat well, eat enough, and eat well.
4. Feeding management Every morning and evening, each patrol pond was found once and found that the situation was taken early. The water level is based on the principle of “Spring Light, Summer Full, and Qiu Qinâ€. Water is usually added from 3 days to 5 days, and water is added once a day during the high temperature season from July to September. Each time, the amount of water is 20 cm to 30 cm to maintain the water quality. Fertilizer, live, tender and cool requirements. There is an aerator of the Tangkou, from June to September every day or every other day at noon to boot 1 hour, when the fish floating head is severe early morning boot to sunrise.
5. Disease prevention and control Strictly carry out disinfection of fingerlings to prevent the entry of fish fingerlings (diseases) into the pool. Feeding baits requires freshness, palatability, and not deterioration. Disinfect the water body regularly and strengthen the management of the water intake to prevent the entry of predator organisms and sewage. The fish season is treated with drugs and baits for prevention.
6. The connection between fishing sales and the market, and the establishment of a marketing plan for commercial fish. The common carp began to be caught once or three times a month from May; grass, cockroach and carp caught the Mid-Autumn Festival, National Day, New Year's Day and Spring Festival and was listed on holiday sales; the carp and carp began to be caught in July, mainly Usually listed, catch large and small, catch up, make a balanced market. The squid is caught by the "flower basket" method, and the other fish are caught by large nets.
