First, the high-quality and large-scale commodity crab intensive mode of adoption of grass snails, improve the ecological environment, put in high-quality crab species, feeding natural high-quality bait, healthy breeding and other technologies, the main attack crab specifications (weighing only about 200 grams) and quality. Mu yield is about 30 kilograms. Second, the quality of the main shrimp (mixed) raising mode changed from polyculture to single-nursery; from feeding eggs and broodstock to the transfer of shrimp seedlings; from single-cultivation to double-bred farming and Macrobrachium rosenbergii or Penaeus vannamei; From the centralized listing to the annual sales and anti-season listing changes, improve the aquaculture production, specifications and quality. More than 50 kg per mu, of which 8 cm to 10 cm large shrimp accounted for 50%. Third, the 80:20 pond main support heterotrophic silver carp model so-called 80:20 pond fish is fed a full price pellet feed, let the fish feed directly to increase pond production, the harvest yield 80% from the intake of food particles The high value of feed eats fish, while the remaining 20% ​​of the output comes from filter-feeding fish or carnivorous fish. This model has production levels of 500 kg, 750 kg, and 1,000 kg. Fourth, the tropical shrimp and shrimp breeding mode using Macrobrachium rosenbergii or white shrimp growth fast advantage, ponds or rice fields to raise a ray of tropical shrimp, after the listing and then raise a squat shrimp, breeding products in addition to fresh sales In addition, it can be used for quick-freezing, holding and processing of shrimp products and other domestic or foreign trade products. The general yield of tropical shrimp 200 kg to 400 kg, 25 kg to 30 kg of shrimp. V. The main (mixed) culture mode of Crawfish crawfish Cultured Crawfish crayfish have low requirements for water surface, extensive management, and low production inputs. Specially raised general up to 500 kilograms per mu. Six, Dashui surface fish, shrimp, crab polyculture pattern General production per mu of fish 100 kg to 200 kg, adult crab 25 kg to 50 kg, about 10 kg of green shrimp. It is necessary to reform the specifications and quality, and to improve the variety structure. At the same time, fisheries, livestock, poultry, forestry, fruit, and grass can be used to raise the economic benefits of integrated breeding. VII. Hegou Ecological Breeding Mode Using river resources, wild fish, shrimp, and crab are the main varieties, and rely on the use of natural feed-based, artificial feed-assisted farming forms to produce high-grade aquatic products that meet food standards. VIII. Production patterns of special aquatic products in rice paddy farming The advantages of rice fields or aquatic plants and aquatic vegetable fields are used to implement rice, fish, crab, rice, fish, shrimp, rice, alfalfa, rice, alfalfa, rice, fish, and shrimp. Seedlings and other forms of planting patterns will increase the overall economic benefits of rice fields. Nine, pond or water surface nesting "small breed" production model in the pond or large water breeding pond mouth, without affecting the main breeding species under the premise of nesting or set cage culture loach, yellow peony, stingray, quail Fish, ponds and other places "small breeds", especially in the middle of the cage set aquaculture better. X. Herbivorous and filter-feeding fish The "double-headed" polyculture model utilizes the advantages of natural rivers, abundant aquatic weeds, large poultry production, and cheap organic fertilizers to develop herbivorous grass carp, head lice and filter feeders. , Squid, this farming mode to use labor to compile the grass-based accumulation of fertilizer, low input, can be wheeled, round-the-clock, listed on a perennial basis. General production of commercial fish 500 kg to 750 kg.
