How to do polyculture in fish ponds in 2020? Prospects and cost-benefit analysis
In recent years, under the pressure of environmental protection and restricted aquaculture, many cages on reservoirs, lakes and other water surfaces have been dismantled one after another. Under such a premise, only fish pond polyculture can ensure maximum economic benefits. So what are the prospects for the fish pond polyculture model in 2020? How should it be

Detailed Explanation of the Key Techniques for Polyculture of Tilapia and Mandarin Fish
Tilapia is not tolerant of low temperatures. In late autumn and early winter, when the water temperature drops to 15°C, it can no longer continue to grow. In fact, a tilapia culture pond can only be used for half a year (May-October). The mandarin fish is different: in winter it does not stop feeding completely and can still continue to grow, only with reduced feeding and

Paddlefish Farming Techniques and Conditions: Both Monoculture and Polyculture Require the Addition of Silver Carp
Summary Models: There are two models, monoculture and polyculture, but both require the addition of silver carp, which can control the amount and growth rate of algae and avoid water eutrophication. Density: Under the monoculture model, at a body length of 50-60 cm and a weight of 1 kg, 80-100 fish per mu; at 2-3 kg, 40-50 fish per mu

Technical key points for polyculturing silver and bighead carp in snakehead farming
I. Pond clearing, preparation and disinfection The pond area for polyculturing silver and bighead carp with snakehead is preferably 6-8 mu. If the area is too small, water quality tends to deteriorate easily, and during the main summer period, high-temperature seasons easily trigger disease. If the area is too large, production input is high, and management is inconvenient. The pond water depth should be about 2 m, with no or little bottom mud left. Weeds around the pond must be cleared, and the pond embankments must be tamped and reinforced to prevent seepage and leakage. 20 days before stocking fingerlings, use quicklime to thoroughly clear the pond at 100-150 kg per mu. After 10 days, use bleaching powder (effective chlorine content 30%) to clear the pond once more at 5-7 kg per mu. After one week, water can be added and fingerlings stocked.

What are the three main benefits of polyculture of fish and soft-shelled turtles in ponds?
The soft-shelled turtle farming industry is one of China's high-quality and high-efficiency special aquaculture industries. Since its development began in the early 1970s at the end of the last century, annual output has now reached more than 100,000 tons, ranking first in the world. Although the current market price of commercial soft-shelled turtles is low, market sales remain undiminished. However, today

How to Raise Fish and Ducks Together? Practical Farming Experience Shared
Fish-duck polyculture is mutually beneficial and is a new way to increase farmers' income. Ducks moving in the water can eat frogs, tadpoles, aquatic insects and other organisms harmful to fish; fish can make use of duck manure, leftover feed and other waste produced by the ducks, keeping the water clean and the environment good

How to polyculture mandarin fish for a high survival rate? Practical methods shared
Mandarin fish is a typical carnivorous fish that only eats live fish and live shrimp. Raising mandarin fish alone requires supporting the culture of forage fish, and the technical requirements are high. If mandarin fish are polycultured in adult fish ponds, the water body can be fully utilized and wild trash fish in the adult fish ponds can be cleared out. In recent years, some farmers have reported
