Hebei sea bream breeding technology

I. Natural Conditions Seawater temperature in Hebei Province is generally stable above 18°C ​​on May 20th of each year. The specific gravity of seawater is about 1.026. Until mid-September, the seawater temperature is suitable for the growth of sea bream, and it is suitable for feeding 2 larvae of sea bream. In addition, many shrimp ponds in Hebei Province have an area of ​​100 mu to 200 mu and a water depth of more than 1.5 meters. In addition, shrimp ponds and small bays with a size of more than 1,000 mu can also receive water. Sea foods are abundant, especially copepods. Hebei Province has a long history of processing sea otters, and the best sea bream products in history are produced in Tangshan City.
II. Farming conditions The Hebei Provincial Aquatic Products Bureau and the local Aquatic Products Bureau attach great importance to the aquaculture and processing of seafood, and often employ experienced experts and technicians to set up lectures to solve the difficult problems in production. As the effect of Oriental shrimp farming in recent years is very unsatisfactory, the survey shows that 70% of farmers lost money, 20% of farmers were flat, only 10% were profitable, and their profits were also very low. At the same time, the cultivation of white shrimp in South America began to appear disease last year. Sea bream breeding can exactly fill the situation in which shrimp ponds can not breed. If a sea bream is set in a shrimp pond, it is a good way to invest less, increase the utilization rate of a unit of water, and increase the unit output (acre profit).
III. History of Breeding In 2002, Tangshan City and Huanghua City in Hebei Province had successful breeding families of sea bream. The maximum size of the culture reached 20 kilograms, and the survival rate of culture was about 10%. Although the Tangshan region has made attempts on polyculture of shrimp and sea bream, due to late release (mid-August), seedlings are of small size and survival rate of seedlings is low. This year, Liaoning Panjin Photosynthetic Aquatic Products Co., Ltd. cooperated with the sea breeding farm of Tangshan City and successfully hatched 3 million juvenile larvae. It is estimated that 12 million discs can be released and 40,000 mu can be used for breeding. For Tangshan Farmers in Hebei Province are all good news. It is estimated that the profit per acre of farmed sea bream is around 1,740 yuan, and there is still a net profit of about 1,000 yuan/mu for manpower and pool rent removal.
