With the continuous development of edible fungi, as the waste after cultivation of edible fungi, bacteria and shells, the countryside is everywhere. According to the practice of fish farmers, the use of fermented shells for feeding fish is suitable for any season. Fish is particularly fond of eating, and after eating, it grows faster and has fewer incidences, which can save expenses and reduce costs, and is worthy of promotion and application. The practice is: choose a mold-free, insect-free, white waste tube to break into, put the appropriate amount of salt, superphosphate, urea and water, then mix in the human and animal dung, cover the waste, and then cover with a plastic film sealed fermentation After 1 month, fish can be fed directly after agitating and re-sealing for half a month.
