Six methods to increase aquaculture efficiency

In recent years, due to the continuous expansion of aquaculture area, many places have seen a situation where the supply of aquatic products exceeds demand, the price is low and sales are poor, and the efficiency is poor. This has seriously affected the aquaculture farmers' income and production enthusiasm. In order to reduce the cost of aquaculture, many farmers have adopted practices such as reducing stocking, implementing extensive farming, using low-priced feed, or using low-cost selling of aquatic products. Practice has proved that these are all negative methods and cannot solve problems fundamentally. Now we introduce six new methods that can effectively improve the benefits of aquaculture, starting from the excavation market and its potential. Wild fish domestication: At present, wild fish such as loach, black peony, yellow locust, etc., such as artificial feeding, high economic value, broad market prospects, great development value. Wild fish domestication, feeding technology is simple, coupled with its strong resistance to disease, easier to keep than domestic fish and the market selling, high prices, the economic benefits of conventional farmed fish is several times or even more than ten times. Summer fish winter raising: The tropical fish that was originally suitable for summer breeding will be used in geothermal, hot spring water or artificial warming culture in winter to implement anti-season production and sales. Such as tilapia, freshwater whitefish, eel and other adult fish and seedlings, through the insulation winter can make the normal growth of fish in the winter, is conducive to mention the morning market, seize the market, improve efficiency. For example, tilapia is listed on the market in winter and spring, which is about 50% higher than the market price in summer and autumn. The introduction of foreign fish: the introduction of some foreign fish to local culture, such as Nile tilapia, the United States California carp, Brazilian oysters, Egyptian pond oysters, etc., but also some of the other provinces of rare fish introduced into the local breeding. The introduction of foreign fish, spending less, significant benefits. As it caters to the fresh and unpredictable psychology of local consumers, the economic benefits must be ideal. Fish fish net raising: that is, high density intensive cages. Fish ponds are raised in the net, have high density, high yield, good efficiency, and convenient catching. They not only greatly increase the utilization of water surface, but also have strong market adaptability. Efficient holding: Fish stock raising, simple technology, low cost, and high profitability are good ways to avoid the peak of listing and achieve high yield and high efficiency. The species suitable for raising are mainly squid, mullet, loach, soft-shelled turtle, crab and other valuable aquatic products with strong vitality. Usually in the summer and autumn high temperature season, when the price is low, raising a period of time, and then choose to market during the holiday period or winter and spring out of stock, the benefit can be doubled. Integrated breeding: Through the comprehensive breeding of famous, excellent and special aquatic products, the benefits can be significantly improved. The main forms of integrated breeding include: polyculture of different food habits and habits, polyculture of common fish and rare fish, and polyculture of fish and shrimp, fish and crab, fish gills, fish turtles, fish snails, and fish gills. , It can also be implemented in various forms of high-yield and high-efficiency integrated three-dimensional planting mode of chickens, ducks, geese, pigs, cattle, grapes and so on.
