Yellow Catfish Polyculture Technology: Efficient Micro-net Cage Farming Method
Setting up micro-net cages in ponds used for farming other aquatic species to raise yellow catfish is a high-yield farming method that increases water surface utilization, featuring simple operation, low investment, easy rearing, fast growth and high returns. 1 Net cage setup The net cage is sewn from polyethylene netting, 2 m long, 2 m wide and 1.2 m high, with a mesh size of 0.5-1 cm. The cage uses a closed stretcher floating-fixed type, with a 9-mesh net cloth as a cushion layer at the bottom, the cushion layer edge being 20 cm high, to reduce feed loss; the upper part of the cage rises 30 cm above the water surface

Key Technical Points for Integrated High-Efficiency Duck-Pig-Fish Farming
Through integrated farming, ducks, pigs, and fish can make full and rational use of energy, achieving the goals of saving feed and attaining high yield and high efficiency. The integrated high-efficiency duck-pig-fish farming method is: 1. Select superior breeds. For ducks, Cherry Valley ducks are best; for pigs, crossbred Landrace pigs and other improved breeds; for fish, mainly silver carp, bighead carp, black carp, grass carp, etc. These breeds tolerate coarse feed and grow fast. 2. Management of duck pens, pig houses, and fish ponds. Duck pens, pig houses, and fish ponds should be concentrated and conveniently located for transport to facilitate management. Keep the

Key points for autumn adult fish farming management
Regulating water quality. In autumn, the water temperature is suitable, making it the peak growing season for fish. Pond fish have strong metabolism and produce a lot of waste, so water quality management should be strengthened to improve the ecological environment. First, keep the pond water relatively deep to expand the water body's fish-carrying capacity, reduce the impact of the water temperature drop after autumn, and extend feeding time. Second, frequently add fresh water. Generally, add water three to four times a month, with each addition raising the water depth by 15 cm to 25 cm. Third, promptly spread quicklime. Do this once every half month, using 15 kg to 20 kg of quicklime per 667 sq m of water surface, dissolve it in water

The integrated fish-goose farming model can increase economic returns by 30%.
Integrated fish-goose farming is a three-dimensional ecological farming model that combines poultry rearing with fisheries management. According to comparisons, under the same conditions, integrated fish-goose farming increases economic returns by about 30% compared with raising fish or geese separately. 1. Benefits of integrated fish-goose farming. 1. Geese are fully automatic, energy-saving and highly efficient aerators for fish ponds. In integrated fish-goose farming, farmers do not need to worry about oxygen depletion in the water caused by weather changes, because whenever the weather changes, the geese will scramble to jump into the water to bathe and chase each other, churning up splashes, which has a particularly good oxygenating effect on the fish pond.

Three defenses to do well in winter fish farming management
In winter, the water temperature is low and there is little light, so there is less phytoplankton in the pond water of fish ponds and the oxygen-producing capacity is poor. Because fish feed and move less, their constitution is relatively weak, which has a great impact on safe overwintering and growth. To ensure the safety and growth of fish in winter, the water quality regulation and management of fish ponds in winter should focus on three defenses. Guard against shallow water. Some fish farmers believe that shallow pond water in winter is good for fish, but in fact this is a misunderstanding. In winter, when the pond water level is shallow, the water temperature changes quickly and the temperature difference is large, which will cause freeze damage to fish and is extremely unfavorable to their overwintering and growth. Winter fish ponds
