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 kilograms per mu, of which 8-10 cm large shrimp accounted for 50%.
Third, the 80:20 pond main raising heterotrophic silver cocoon model so-called 80:20 pond fish is fed full-grain pellet feed, allowing fish to feed directly to increase pond production, the harvest yield of 80% comes from feeding The high value of pellet feeds 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 use Macrobrachium rosenbergii or white shrimp South American fast growth advantage, the pond first raise a handful of tropical shrimp, after the listing and then raise a new one, the cultivation of products in addition to fresh sales, For quick-frozen, holding and processing shrimp and other products domestic or foreign trade. General production of tropical shrimp 200 kg -400 kg, 25 kg -30 kg of shrimp.
Fifth, the large-surface fish, shrimp, crab polyculture model general production of 100-200 kg of fish products, adult crabs 25 kg -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.
Six ponds or large water surface nesting "small breeds" production model in ponds or large water surface of the breeding pond mouth, without affecting the main species under the premise of raising or set up net cage breeding loach, astragalus, carp and other places " Small variety."
VII. The “double-headed†polyculture pattern of herbivorous and filter-feeding fishes utilizes the advantages of natural rivers, abundant aquatic plants, large livestock and poultry husbandry, and low-cost organic fertilizers to develop herbivorous grass carp, head lice, and filter-feeding crickets. , 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 fish 500 kg -750 kg.
