Detailed Explanation of Key Points for Wild Duck Cage-Bed (Net-Bed) Farming Technology
1. Selection of duck house: Choose a place with dry terrain, quiet surroundings, abundant water, good ventilation and lighting, and convenient transportation. Under the net frame inside the house, a semi-sloped cement floor can be laid to facilitate washing and cleaning of duck manure. The building area is determined by the scale of raising; for example, to raise 1000,

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.

Clever Methods and Tips for Raising Ducks with Light-Trapped Insects
The technique of raising ducks with light-trapped insects applies the principle that insects are phototactic, collecting insects in a water basin at night to feed ducks. Raising ducks with light-trapped insects can save 30%-40% of feed, correspondingly reducing duck-raising costs and improving duck-raising benefits. It can also draw the various mosquitoes and flies that bite pigs and cattle

Sharing Experience in Micro-Cage Culture of Yellow Catfish
Setting up micro-cages in ponds used for culturing other aquatic products to raise yellow catfish requires little investment, yields quick results, and is easy to operate. Cage setup. The cage is sewn from polyethylene netting, 2 m long, 2 m wide, and 1.2 m high, with a mesh size of 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 is 20 cm high to reduce feed loss, and the upper part of the cage rises about 30 cm above the water surface. A square plastic basket made of 18-mesh polyethylene window screen, 10 cm high and 30 cm on each side, is used as a feeding platform and placed in the middle of the cage body, one per cage. The cages are set at the water inlet of the fish pond, and 1-3 cages can be placed per mu of fish pond. The cages can also be set in open waters with fresh water quality, sufficient dissolved oxygen, shelter from wind and sun, and no pollution, arranged in a straight line, with a cage spacing of 4 m and a row spacing of about 10 m. Water hyacinth or alligator weed is transplanted inside the cage to cover about 2/3 of the cage area.</p><p></p><p>Fingerling stocking. The cages are put into the water 1-2 weeks before fingerling stocking. The fingerlings are required to be disease-free and injury-free, robust, and uniform in size. Stock 100-150 large-size fingerlings weighing about 20 g each per square meter.</p><p>Feeding management.</p><p>① Feeding: Common feeds include small miscellaneous fish, snail and clam meat, earthworms, silkworm pupae, livestock and poultry viscera, and animal blood, etc. Feed according to the principles of fixed time, fixed location, fixed quality, and fixed quantity to ensure the yellow catfish eat enough and eat well and grow quickly.</p><p>② Water management: Keep the water quality fresh and the dissolved oxygen sufficient. Observe the fish activity every day, check whether the cage is damaged, remove sick and dead fish from the cage, and keep the water body inside the cage clean. Clean the cage once a week to ensure normal exchange of water inside and outside the cage, and adjust the height of the cage in time when the water level changes.</p><p>Disease prevention and control. Soak the cage in bleaching powder solution for 30 minutes before it enters the water; soak the fish body in salt solution before the fingerlings enter the cage to kill pathogens and parasites on the body surface; splash quicklime water over the whole cage for disinfection once every 10-15 days; regularly hang bags of copper sulfate and ferrous sulfate mixture; about every 20 days, make medicated bait with antibiotics and feed continuously for 2-3 days. Through the above measures, fish diseases can be prevented during the culture cycle.</p>
