Techniques for Using Biogas Residue and Biogas Slurry in Loach Farming
1. Site Selection and Pond Construction Choose a spot behind or in front of a house where the water source is reliable, drainage and irrigation are convenient, it is sheltered from the wind and faces the sun, and it is close to the outlet of a biogas digester. The size of the pond can be adapted to local conditions; generally, an area of 10-20 sq m is suitable, with a pond depth of 1.2 m. The pond walls should be built with lime or bricks, and the surface should be smoothed with cement. Special water inlet and outlet should also be built, with wire mesh fitted at the inlet and outlet to prevent the loaches from escaping. A shade shed should be built above ground, and an insect-attracting lamp should be installed.

Tilapia Farming: A Detailed Guide to Overwintering and Broodstock Preservation Techniques in Greenhouses
Tilapia is a tropical fish with relatively poor cold resistance. Generally, when the water temperature drops to 12°C, tilapia will suffer frostbite or die. Oreochromis niloticus × O. aureus hybrids have relatively stronger cold resistance, but they still cannot overwinter in low-temperature environments for extended periods. In China, apart from Hainan, Taiwan, China, and parts of Yunnan and Guangdong provinces where natural overwintering is possible, tilapia in most regions cannot overwinter in natural conditions and must adopt corresponding overwintering and broodstock preservation measures to ensure the smooth overwintering of parents and fry.

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,

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.

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.
