(i) Rationally raising and raising water surface regrowth index. (1) Putting on famous fish species such as cockroach, cockroach, and stingray. Generally, every 1067 hectares of water can be nested with 5 - 8 cm of 10 - 15 tails, 5 - 8 of 150 grams of juveniles, or 50 - 80 of 10 cm of stingrays. In particular, the surface of crabs can be raised and these breeds can be preyed on wild fish and shrimps to avoid competition with main breeds for competition, competition for oxygen, and competition for space. This will not only increase the output of major species, but also increase the yield of 5 kg. , Cheng Hao 2 - 3 kg, 25 kg of commercial fish Astragalus. (2) Nesting grass carp species such as grass carp, praying mantis, praying mantis and praying mantis can make full use of water space to solve large-scale fish species cultivated in the coming year. Generally, every summer, the summer flower size is set at 3 to 5 centimeters. With 1,500 tails, it can produce 30--50 kg of fish. (3) Fish, crabs and other breeding waters will be placed on the green shrimp seedlings. Generally, about 10,000 shrimps of 1--2 centimeters will be planted per 0.067 hectares, and 5 to 10 kg of shrimp will be harvested. (4) Penaeus vannamei breeds crabs on the surface of the water, or uses double squid and prawn (a pair of white, black and white prawn or conventional fish); .
(B) arrest the listing, do a good job selling products at the right time. Common oystercatchers, clams, grass carp, clams, and clams began to be caught in the market from early to late July. The shrimps are harvested year round, and they can also be picked up from the end of June to the middle of July. In the months of August and August, the “Yellow Crabâ€, which has been caught up to the specifications, will be listed; special aquatic products such as loach, yellow peony, black peony, and soft-shelled turtle shall also be collected and listed according to market conditions and breeding density. The timely listing of round-fishing cultured products is one of the important measures to improve the economic benefits of breeding.
(3) Input enough feed to increase specifications and increase production. From July to September, the water temperature is high, and the metabolism of cultured animals is strong, which is a critical period for its growth. Should pay close attention to this period, according to the feeding characteristics of various cultured species, choose a variety of feeds with wide sources, good palatability, complete nutrition, and low prices, adopt scientific feeding methods to increase feed remuneration, reduce production costs, and increase aquaculture production. Conventional fish should be fed with full-priced compound feeds; shrimps should be fed with fine-grain feed; crabs should be chopped (spinae, clams, clam meat, small junk fish, shrimp, etc.) and refined (bread clams, wheat flakes, mixed feed Such as), Qing (water plants, pumpkins, potatoes, etc.) with a reasonable mix of feed; Chinese wolfberry, wolfberry, black peony, yellow peony and other famous fish to feed small trash fish, snails, livestock and poultry meat, quail and other meat-based feed; At the same time, all kinds of aquaculture water must be fertilized to cultivate the natural biological feed in the water, adhere to regular, qualitative, positioning, quantitative feeding, ensure that all cultured objects eat enough, eat well, eat well, and grow quickly and healthily.
(d) Strengthen management and control the occurrence of breeding diseases. (1) Strengthen water quality management. By adding water, changing water, planting grass, snail, chemical, biological (splash lime, using EM bacteria, photosynthetic bacteria), mechanical oxygenation and other measures to ensure that the water quality is "fat, live, tender, cool" and prevent fish shortages. Oxygen floating heads and flooding ponds occur. (2) It is necessary to strengthen nutrition and increase the self-immunity of the cultured species. (3) Adopt measures such as seedlings, food farms, tools, bait fertilizer disinfection, and regular drug prevention measures, so as to prevent problems. (4) Do a good job of cleaning and sanitation and strengthen the management of patrol ponds so as to prevent the harm of enemy pests to breeds. (5) We must do a good job of preventing floods, preventing drought, preventing flight, and stealing, so as to ensure that every link is absolutely safe.
(e) Market-oriented to ensure the best-selling products. (1) establish brand awareness. It is necessary to produce high-quality aquatic products that are of good quality and marketable (such as large-scale crabs, imitation wild oysters, and high-quality squid, etc.), and also to focus on brand protection, to make bigger and stronger brands, and to increase market share; (2) to promote New technologies for healthy farming, ecological farming and pollution-free farming. Strengthen the monitoring of the environment, water quality, soil, production inputs (feed, additives, drugs, etc.), strengthen the construction of aquatic pollution-free bases, and produce aquatic products that meet domestic and international safety and quality standards, and enter large and medium-sized cities and supermarkets. Try to earn foreign exchange through exports. (3) Master market dynamics and understand market conditions. It is necessary to sell the cultivated products and sell them at an ideal price.
