Carp farming density should be reasonable, with appropriate polyculture of other fish species
Abstract The recommended carp farming density is about 3000 jin per mu, and it is advisable to polyculture about 300 jin of black carp or silver carp and bighead carp together. The carp farming density mainly depends on the water quality environment, climate conditions and farming techniques of the location of the farm. Farming density For conventional farming methods

Polyculture Techniques for Silver Carp in Crayfish Ponds
Abstract Polyculture of crayfish and silver carp maximizes the use of water space. Crayfish are benthic animals that mainly move about on the bottom, while silver carp and bighead carp mainly inhabit the middle and upper layers of the water body. Silver carp do not need to be fed compound feed; they mainly feed on plankton in the pond, so

Detailed Explanation of Key Techniques for Integrated Lotus Root and Loach Culture
Is integrated lotus root and loach culture feasible? Lotus root grows in mud, and loach also lives in mud. Raising loach in a lotus root pond is a form of ecological aquaculture, mutually beneficial to both. So how do you raise lotus root and loach together? Let us walk you through it below.

Key Technical Points and Daily Management Methods for Polyculture of Rice Field Eels and Loaches
Whether it is pond aquaculture or cage aquaculture, the following polyculture model can be adopted to increase profits. I. Building a good aquaculture pond for polyculturing rice field eels and loaches: Choose a location that is sheltered from the wind and faces the sun, has a quiet environment, and has convenient water sources. Cement ponds or earthen ponds can both be used, and cage polyculture can also be carried out in reservoirs, weir ponds, small ditches, and small rivers. The area is generally 25-150 sq m. If cement ponds are used to raise rice field eels and loaches, dealkalization treatment must be carried out before releasing the fry; if earthen ponds are used for aquaculture, the soil is required to be hard and the pond bottom must be tamped solid. The pond depth is 0.8-1.5 m. Whether it is a cement pond or an earthen pond, a 30 cm layer of fertile mud must be filled into the pond bottom. Fertile mud with more organic matter is best, as this helps rice field eels and loaches dig caves to live in. When building the pond, water inlets and outlets must also be set up, and the water depth should be kept at 15-20 cm. The water inlet and outlet must be tied securely with fish-blocking nets to prevent rice field eels and loaches from escaping. About 10 days before releasing the fry, thoroughly disinfect the aquaculture pond with quicklime, and 3-4 days before releasing the fry, drain the pond water and then inject new water.

What to do when fish farming profits are low? Polyculture of fish and soft-shelled turtles helps you increase returns
Benefit analysis of fish-turtle polyculture. In ponds with imitation-ecological turtle farming, the pond turtles have a good growing environment, the water quality is pollution-free, and they are fed processed grass carp, common carp and other fish, which are nutritious and highly palatable. One month after young turtles are put into the pond, they feed well, and their body color gradually becomes similar to that of wild turtles.

Methods and Technical Key Points for Polyculture of Yellow Catfish in Ponds
Polyculture of yellow catfish in ponds is also called pond supplementary culture or pond mixed culture of yellow catfish, which can be yellow catfish (Pelteobagrus fulvidraco) or darkbarbel catfish (Pelteobagrus vachelli). Because yellow catfish has strong environmental adaptability, the aquaculture technology for polyculture of yellow catfish is relatively simple. (I) Pond condition requirements According to the
