Application of EM raw material in river crab breeding

In 2001, we chose Jiangxi Tianyi's EM original dew, which has obvious effects in environmental restoration and improving the body's immunity. The amount of promotion and application in that year reached 15 tons, and it grew at a rate of 50% every year, In the traditional method, salt or potassium permanganate is used to soak the seedlings. Now many farmers use EM raw dew to soak the crab seedlings before stocking. The specific method is: add 1000 ml of EM raw dew to In the process of high-yielding and efficient river crab breeding, the daily feeds mainly include fresh small fish, frozen marine fish, pellet feed, etc. In particular, fresh small fish and frozen marine fish contain a large number of bacteria, which can easily cause the occurrence of crab enteritis and pollute the water quality. If fresh small fish or frozen marine fish are fed, for every 100 kilogram of fresh small fish or frozen marine fish, slice them with 100ml EM raw liquid, mix well, soak 3 hours before feeding. At this time, 100 grams of chlorine dioxide should be sprayed throughout the entire pond to disinfect the water, and then EM original dew 500 ml of chemical water should be sprayed throughout the entire pond at intervals of 15～EM original dew have been widely used in our city, and have changed from the original publicity and promotion period to the active application period by farmers. This is a strong guarantee for the development of ecologically efficient fisheries in our city and is of great significance to the sustainable development of fisheries.
