Intensive care
Intensive breeding, that is, pure tilapia breeding, feeding feed throughout, graded seedlings. It can be cultivated for 2 to 3 years per year, but the demand for aquaculture technology is high, and the demand for breeding equipment and conditions is also large. The author visited Mr. Li, the president of Huazhou, Guangdong Province. He has 10 acres of ponds, a typical intensive mode. The whole feed was fed and the seedling density was 5000/mu. The crude seedlings were released in June and the fish was caught at the end of October. The total weight of the collected fish is 44,000 pounds, the fish price is 3.9 pounds, and the total fish is 171600 yuan. 1320 packs of feed, 120 yuan for each package, and 158,400 yuan for feed. Together with fish fry, pond rent, water transfer, labor and electricity, it is basically a loss. The above aquaculture data has already been at a high level in the industry, but it is also difficult to escape the loss of the claws under this low price of fish. This model, this year, relies on "price" to live, and many farmers say it is "breeding gambling", just like buying Lottery.
However, I believe that there is no wave peak where no peak, any one commodity will not be lower than the cost price. This year is only a special year. Everyone need not be too nervous and overly pessimistic. After the storm, it is a rainbow. Intensive culture is a sign of the development and civilization of modern aquaculture.
Polyculture
Polyculture, that is, a variety of species cultivated in a pond, ecologically complement each other, complement each other, and the stocking density is relatively reasonable. This model has achieved good economic benefits in the Nansan, Dongli and Taishan areas. The fish-shrimp polyculture model is a highly profitable tilapia farming model that makes rational use of the ecological environment and is currently limited to development in coastal areas. The author made a special visit to Mr. Liu, an electric white farmer, in view of the polyculture pattern of tilapia. He has 15 mu of tilapia, supplemented by Penaeus vannamei. The seedlings were planted at the beginning of April. The density was 1,500 tails/mu in Luofei and 40,000 tails/mu in South America. This year, it caught 78,000 yuan of shrimps and caught 95,000 yuan. Before tilapia fry was released, white shrimp No. 0 was used. After the fry was released, mixed feed was used. A total of 95,000 yuan was used for feed, plus other costs were tens of thousands this year. Mr. Liu told the author: This model is suitable for ponds with low salinity. Even if the risk of high incidence of white shrimp, tilapia can also protect the original, even small gains. This model can also use the omnivorous characteristics of tilapia to eat sick shrimp to prevent the spread of shrimp disease.
Three-dimensional culture
Three-dimensional culture popular is fish, pigs, ducks, fish and polyculture. In the early period, livestock and poultry manure was used as the bait, which grew to two or five to two and began to be fed. If the price of fish continues to slump, then it will insist on not feeding and completely excreting. The greatest benefits of three-dimensional culture are the low cost and high success rate. Disadvantages: Fish grow slowly and produce low yields. Due to centralized listing at the end of the year, prices are often not high. It is understood that if there are more chickens, ducks and pigs to be cultured on fish ponds, the feed requirement is relatively small, but the water quality is poor. In recent years, the three-dimensional culture model has been quietly rising in the tilapia aquaculture industry. With curiosity, the author came to the most concentrated Maoming Huazhou region in the three-dimensional culture and visited the most influential and representative fish and pig three-dimensional breeding giant Mr Peng in the area. He has 90 acres of fish ponds in Xin’an, Huazhou, and 2000 pigs at the edge of the pond, with a density of 2000 pigs per mu. One year down, more or less caught 150,000 catties of fish, totaling 570,000 yuan in fish, and 390,000 yuan in feed. The feed cost per catty of fish can be kept at 2.6 yuan. In the downturn, tilapia culture has considerable advantages.
However, this model may have an addiction to drug residues due to the raising of livestock and poultry. If, in the livestock and poultry excrement, illegal drugs remain, they will flow into ponds, and the fish and shrimps cannot be decomposed, which can easily lead to excessive drug residue.
The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
