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.

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.
