How is it that the per-mu yield of a fish pond can reach over a thousand jin?
Summary The per-mu yield of fish farming in ponds is generally around 1000 jin, and with high yields it can reach around 4000 jin. Different fish species and rearing methods will affect the yield. Pond fish farming generally adopts a polyculture model, and the stocking density of fish is determined according to the size of the fish species, but it should be noted that before stocking, they must be soaked and disinfected in a 4% salt water solution for about 10-15 minutes.

A Detailed Guide to Arapaima Farming Methods and Key Technical Points
Abstract Fish tank requirements: Arapaima grows quickly, so a fish tank with a length of 4.5 m, a width of 1.5 m and a height of 1.5 m should be chosen, and the top must be secured against escape. Water quality requirements: It prefers weakly acidic water, and the suitable water temperature is around 24°C-29°C. Feed requirements: For animal feed

A Detailed Explanation of the Key Points of Australian Redclaw Crayfish Farming Technology
Summary Pond conditions: The pond water quality must be fresh and rich in dissolved oxygen. Shrimp fry stocking: Before stocking, the pond must be dried and disinfected, and pests such as catfish and snakes must be thoroughly removed from the pond. Feed feeding: Feed small trash fish, river snails, shrimp compound feed, and so on. Daily management

When is the most suitable time to farm crayfish?
Summary: The crayfish farming time can be determined according to the size of the shrimp fry, and shrimp fry can be stocked three times throughout the year. First stocking: carried out from late March to early April, overwintering fry can be stocked, with a stocking rate of about 4,000 tails per mu. Second stocking: carried out from late May to early June

Detailed Explanation of Key Points of Off-Season Crayfish Farming Technology
Abstract Farming pond: Choose a pond facing the sun and sheltered from the wind, dig several strip-shaped trenches of the same size in the pond, clean the pond bottom, filter the water and fill it, then plant water hyacinth and other aquatic plants, and finally install a microporous aeration pipe in the strip-shaped trenches. Shed frame: Two layers of thick plastic film need to be covered on the built shed frame. Stocking fry: Fry can be stocked in mid-to-late November, with about 50 kg of semi-commercial shrimp stocked per mu. Feeding: Feed once a day, and make sure the dissolved oxygen content in the water is sufficient.

What are the first-aid methods for oxygen deprivation in crayfish?
Summary Excessive density causes oxygen deprivation: adjust the breeding density in time and turn on the aerator to add oxygen. Overfeeding causes oxygen deprivation: adopt a feeding method with fixed quantity, fixed quality and fixed timing, feeding bait once each morning and afternoon. Excessive waterweed area causes oxygen
