Precision farming streamlines, standardizes and digitizes aquaculture, which enables aquaculture operators to operate and execute according to the mode, which is beneficial to reasonably arrange production and organize sales, improve aquaculture production efficiency, timely discover environmental hidden dangers and diseases during aquaculture, improve aquaculture survival rate, reduce costs and increase economic benefits.
The key of grass carp precision culture mode lies in "precision", which is embodied in four aspects: "precision stocking, precision feeding, precision drug use and precision water transfer". The main points are as follows:
Accurate stocking-plan the proportion and quantity of grass carp and mixed fish farming, balance stocking in production, catch and release in turn, and improve unit output.
Precision feeding-the biggest cost in farming is feed. The bigger the grass carp, the higher the proportion of feed cost. The traditional feeding mode mainly based on granular materials has caused waste due to the characteristics of granular materials and the operation of farmers. Although some of them can be used for polyculture of fish, a considerable part is still lost to water, which increases the cost and the pressure of water quality regulation. The intensive culture mode of grass carp is mainly granular feed in the fingerling stage of grass carp in summer. In other seasons, the feeding mode of high-quality series of expanded compound feed is the main one, supplemented by granular feed. In actual production, the feeding rate is optimized and adjusted with reference to specific factors such as water temperature, dissolved oxygen and the ratio of grass carp to mixed fish culture.
1, accurate stocking-the proportion of grass carp polyculture is balanced, the substances discharged from grass carp are effectively utilized, and the additional benefits are obvious.
2, accurate feeding-all use Taishan grass carp king puffed compound feed, high-quality raw materials, superfine grinding, less waste, low feed coefficient, fast growth, healthy fish, high digestibility and less ammonia nitrogen emission.
3, accurate medication-prevention first, the whole process of breeding is basically disease-free, and the survival rate reaches 99%.
4. Accurate water transfer-make full use of the aerator, with high dissolved oxygen, normal physical and chemical indexes, good water quality, fast fish growth, low cost and high benefit.
The above-mentioned customers have implemented the grass carp precision culture mode in production, and the feed coefficient, drug use cost and water transfer cost have been greatly reduced, the survival rate has been improved and the benefits have been obvious. Even if the market is depressed, customers are still profitable.
Traditional aquaculture, which relies on experience and feeling, is no longer applicable in the market environment with low profit and fierce competition. It is the general trend to be gradually replaced by the precision farming model based on data analysis. Feed enterprises should constantly improve product quality, optimize breeding mode, provide suitable breeding solutions to serve customers and improve the refined management level of customers. Customers should also keep pace with the times and accept the advanced and scientific precision breeding mode in order to be invincible in the unpredictable market.
