"White shrimp + California perch" rotation, mu earn 40,000 yuan! How did he do it?
"I have been raising white shrimp for 6-7 years, and the yield is generally 900-1100 kg/mu. This year, I will take turns to raise more California perch." Aquaculture information that gets from a farmer in Hunan, reporter involuntarily raises 12 minutes interest.
The farmer is from Hunan boss Chen, is a 15-year experience of breeding veteran, the early gRASs carp breeding, now to raise white shrimp, California perch. As a traditional inland freshwater aquaculture area, Hunan is dominated by four major fish, and most of the farmers are limited to freshwater special fish. Boss Chen is a bold attempt to breed white shrimp, per mu yield level comparable to the Pearl River Delta. He rotated California perch on a white shrimp pattern, a highly efficient, high-threshold combination rarely seen in central China.
Desalinate cast seedling into "high yield secret" per mu yield broken thousand catty benefit 20,000 yuan/mu
Around 2014, Boss Chen is still a gRASs carp farmer, suffered the worst market on gRASs carp, 4.5 yuan/catties gRASs carp price let the pond benefit straight contact bottom. In 2015, the rise of white shrimp in Hunan turned to farming, forming a scale of nearly 10,000 mu in a short period of time. Boss Chen decided to enter the market and became the first batch of local shrimp farmers to "eat crabs". Because of the farmers at that time group research technology, the shrimp material brand to carry out technical services, good market atmosphere so that many people have been 400-500 jin/mu of good results, including Boss Chen.
"Shrimp farming in freshwater areas is much more difficult than in coastal areas, and grinding technology is key." Boss Chen mentioned that the market was just established in the early years, the technical level is not mature enough, the success rate of breeding is too stable, and the aquaculture farmers with weak technical foundation quickly quit the market. On the contrary, Boss Chen with careful research technology, continuous 6 years of breeding success, the level of yield per mu has gradually increased, and eventually maintain at about 900 jin/mu, mu yield benefit of 14000-16,000 yuan/mu. This year, the yield per mu is estimated to reach 1100 jin/mu, and the yield benefit per mu is close to 20,000 yuan/mu.
Boss Chen believes that in many technical operations, the desalination of seedlings and pond pond to raise shrimp to determine whether the high yield. Therefore, each time the boss Chen buy P5 seedlings must be hands-on, need to be familiar with the factory of young shrimps, salinity and personally use adjust the desalination pond salinity to temporarily raise the sea salt, finally several salinity gradient, gm to take down every day two salinity, temperature is low in the morning and afternoon once each, until reduced to adapt to the salinity of young shrimps to close to local freshwater range.
Hunan Feed Co., Ltd. technical manager mentioned that the desalination process is very careful farmers patience, it must take 7-10 days to slowly advance, if necessary, need professional technicians to help control the stability of water quality, Boss Chen is very careful in this link. On the contrary, at present many aquaculture farmers desalinated shrimp seedlings, do not pay attention to water quality data, all by feeling operation, shrimp seedling stress, survival is low, per mu yield is difficult to exceed 500 catty/mu, local even appeared even thousands of acres of shrimp pond early steal dead phenomenon.
The lack of trace elements required by white shrimp in inland fresh water area can easily affect the growth rate and disease resistance. After being raised in separate ponds, Boss Chen paid attention to water calcium source, carbon source and multi-mineral supply to promote the growth of shrimping, while feeding fermentation materials "Fu Shrimp Kang" and "Shrimp Zhuang Le", so that white shrimping intestinal thick, strengthen disease resistance. It is reported that Boss Chen refers to the south China shrimp raising model, every 15-30 days, into the pond to cast povidone iodine disinfection treatment, with three yellow Chinese herbal medicine, so that the pond shrimp seedlings to achieve the overall effect of internal medicine.
Expanding mode of Rotating California perch following Guangdong to make "big things"
Boss Chen discloses, oneself breed breed business develops closely with feed group. Since 2015, The Feed Group has concentrated on the central China market, and the elite soldiers and strong technical services will enter the Lianghu market. Many white shrimp teams come from Guangdong and Guangxi, and the Hunan Yuehai technical team is one of them. Under their service and guidance, Boss Chen has been breeding white shrimp with high yield and success for years. In 2021, he will try to rotate and raise more California perch to expand the breeding mode and increase pond benefits.
It is reported that in April and May this year, Boss Chen divided a 5-acre pond for the California perch splash mark seedlings. In July and August, the splash mark was as thick as 10 sides (about 2cm/tail size), and two ponds were divided into 8 acres and 12 acres respectively. After the white shrimp was sold out, Boss Chen carried out the California perch subdivision pond, and the seedling density was 3500 per mu. It is expected that stir-band fish could be produced in March of the next year, and the specification could reach 0.8-0.9 kg/mu.
According to Boss Chen's model combination, the breeding cycle of white shrimp is from June to September, and California perch is separated from The pond in September to the next May. The pond surface has just completed one year of operation. The shrimp producing node and the rearing node of Perch California are both at the market peak, and the total yield per mu will be increased by at least 20,000 yuan per mu if the benefit of perch California is increased by 3000 kg/mu in the pond.
In order to ensure the success of the first trial breeding, Boss Chen paid special attention to the flowering and seedling standard of California perch, so as to improve the survival rate of seedlings and enhance the health of the fry. Boss Chen into the previous white shrimp breeding technology, the "fu Shrimp kang" mixed into the seedlings feed, and pay attention to the cultivation of water spider, two ponds fry growth obvious. It is reported that the current specification has reached 0.1 catty/tail, it is expected to reach 2 more than 2 catty/tail in September, and the survival rate of flowering reaches 50%, the survival rate of standard rough reaches 30%, and the high yield of surrounding breeding groups is nearly 10%.
"The white shrimp + California perch rotation mode will definitely attract attention and even become the mainstream mode in the local area." Boss Chen revealed to reporters that the current white shrimp + California bass rotation mode has been completed, the technical team leads the pond head service and technical control, local dealers coordinate feed, animal protection, shrimp seedlings and other resource supply issues, has the model promotion basis.
