The Ministry of Agriculture and Rural Affairs announced on April 1 that in order to accelerate the green development of the aquaculture industry and promote industrial transformation and upgrading, they decided to implement the “Five Actions” for green and healthy aquaculture from 2020.
Promotion of ecological and healthy farming models
In 2020, we will focus on the demonstration and promotion of pond engineered circulating water, industrialized circulating aquaculture, integrated rice and fish breeding, deep-water wind-resistant cage culture, large-area ecological enhancement culture, saline-alkali water green culture, multi-nutrition level comprehensive culture, and 9 major technical models including symbiotic ecological breeding and container-type circulating aquaculture.
Promotion action of farming water treatment model
In 2020, we will focus on demonstrating and popularizing the five typical treatment technology models of pond bottom sewage tail water treatment technology, centralized continuous pond culture water treatment, constructed wetland water treatment, “flow tank +” tail water treatment, and factory circulating water treatment.
Action to reduce the amount of medicine used in aquaculture
In 2020, we will focus on five technical measures including the development of ecological farming, the use of the high-quality seed, strengthening the prevention and control of disease, guiding the standardization of medicines, and strengthening production management. The amount of use decreased by an average of more than 5% year-on-year, and the use of antibiotics and veterinary drugs decreased by an average of more than 10% year-on-year, forming a batch of standardized technical achievements and drug reduction technology models.
Action to replace juvenile fish with compound feed
In 2020, it will focus on 12 provinces (regions) including Liaoning and Jiangsu, and choose to focus on breeding freshwater fish, crabs, etc. to establish more than 50 experimental extension points for compound feed to replace juvenile fish. Strive to replace the replacement rate of marine fish such as large yellow croaker, perch, grouper, flounder and other marine fish, not less than 60%, and the replacement rate of freshwater fish such as largemouth bass and snakehead are not less than 80% and 50% respectively The substitution rate of crabs such as swimming crab, Blue Crab, and Eriocheir Sinensis is not less than 30%, 30%, and 60% respectively.
Action to improve the quality of aquatic seed industry
Guided by the concept of green development, encourage the breeding of high-quality, efficient, multi-resistance and safe new aquaculture varieties, strengthen variety performance testing, support major breeding to rejoin joint research and standardize the expansion of multiplication production, and vigorously promote “integration of breeding and propagation to improve the level of improved aquaculture breeding”.
