What are the methods for killing foxes and removing their pelts?
For foxes raised for commercial use, when their fur is mature they should all be killed and skinned, and the raw pelts given preliminary processing. Foxes are relatively large in body size, so the method of killing mink by breaking the neck vertebrae cannot be used. Fox farms in various places have worked out several practical methods for killing foxes, mainly the drug method, the heart air injection method and the electric shock method. Whichever method is used, the principles are that the operation must be simple and practical, the killing must be quick, the pelt must not be damaged, and the fur must not be soiled. 1.

Pollution-free management key points for raising yellow catfish (Pelteobagrus fulvidraco) as a supplementary species in lotus ponds
Lotus ponds contain many benthic organisms, aquatic insects, plankton, and pond weeds, which can provide food for the fish, while the fish feces and leftover bait can provide fertilizer for the lotus, and the fish activity loosens the soil, providing good soil conditions for lotus growth. Because lotus leaves shade and block light, the light intensity in the lotus pond environment is relatively weak, which suits the yellow catfish's requirement for feeding and growth under low light. Pond construction. Choose a pond with abundant water sources, good water quality, fertile soil, flat terrain, convenient water intake and drainage, and strong water and fertilizer retention,

Fox Molting Patterns and Methods for Assessing Pelt Maturity
Foxes begin shedding and replacing their underfur every spring, and the guard hairs then quickly fall out and new guard hairs grow in. Molting in foxes starts first at the head, neck, and forelimbs, then moves to the flanks, back, and abdomen, and only last do the rump and tail hairs shed and regrow. The completion of hair replacement on the body surface does not mean that the fox's fur and skin are fully mature. The assessment of pelt maturity is mainly based on indicators such as the color, fineness, density, length, softness and flexibility of the fur, as well as the color, thickness, and strength of the skin.
