Benthic bait biological culture medium for breeding ricefield eels and using method thereof

The invention relates to a benthic bait biological culture medium for breeding ricefield eels and a using method thereof. The culture medium is prepared by uniformly mixing corn, fibers, bagasse, distillers' grains, wheat bran, bean dregs, rice bran, sodium humate, attapulgite, calcium fluoride, biological organic fertilizer and organic matter; the cultured bait organisms can replace over 50 percent of artificial feed, so the culture cost is reduced greatly; the high-quality benthic bait organisms can provide a nutrition guarantee for the quick growth of ricefield eels, and therefore, the breeding scale, yield and benefit are increased considerably; and the bred high-quality ricefield eels can increase market competition power and reduce breeding risks.
