Key Technical Points for High-Yield Carp Pond Culture
I think everyone is very familiar with crucian carp. Crucian carp is eaten quite a lot in daily life. Crucian carp has many bones, but because its price is relatively cheap and it is also plentiful in the market, it is deeply loved by the public. The requirements and threshold for crucian carp farming are very low, so

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.

Key Technical Points for Artificial Incubation and Farming Management of Paddlefish
Paddlefish (Polyodon spathula) is a large freshwater economic fish native to North America. Due to its unique body shape and flat, elongated snout, it can also serve as a valuable ornamental fish. When polycultured in ponds, it can both regulate the farming environment and improve water quality, while also yielding relatively

Key Technical Points for Overwintering Management in Bullfrog Farming
The bullfrog is a poikilothermic animal, and begins hibernation when the water temperature drops to 6-12 degrees. The following points should be noted in hibernation period management. 1. Prevent cold damage. Bullfrogs hibernate in two ways: lurking at the bottom of the water and in the ground. During the overwintering period, a 2 cm water layer must be maintained in the frog pond, and a cold-proof shed should be built over the water surface with branches or straw.

Key Technical Points for Overwintering Management in Enclosed-Gully Rana Frog Farming
Rana frogs have the habit of hibernating and overwintering underwater. From late September each year to mid-to-late April of the following year, a period as long as 6 months, overwintering management in artificial enclosed-gully frog farming means, according to the living characteristics and needs of Rana frogs during this period, artificially selecting and creating suitable overwintering sites and water environments,

Key Technical Points for Winter Management of River Crab Pond Aquaculture
2015 was a relatively warm winter, with daytime temperatures basically staying above 10°C. A warm winter is relatively special for river crabs, as their living habits are greatly affected by temperature. This is mainly because river crabs begin feeding at 10°C and feed normally above 16°C. Therefore, under warm winter conditions, the activity capacity and feeding of river crabs are significantly enhanced. Overwintering is a foundation, and how to let river crabs overwinter healthily and smoothly will directly affect our aquaculture benefits in 2015. This article shares some communication with everyone on the key points of winter management of river crab ponds.

Detailed Explanation of Key Points on Pufferfish Pond Cultivation Techniques
I. Small-Size Fingerling Cultivation (I) Pond Selection Ponds require an abundant water source, unpolluted water quality, and small annual water temperature fluctuations. If brackish or freshwater aquaculture is used, ponds should be built in locations where water can be pumped conveniently, with short routes and low pumping heads. The pond bottom should be basically non-leaking,
