Abstract

The invention discloses a leech feed capable of improving water quality. The leech feed capable of improving water quality comprises the following raw materials in parts by weight: 30-50 parts of corn, 6-12 parts of rapeseed meal, 8-16 parts of kelp powder, 4-10 parts of oat flour, 10 -20 parts of brown seaweed, 15-25 parts of starch, 6-12 parts of azoila imbricata, 10-18 parts of puffed blood meal, 10-20 parts of earthworm meal, 10-20 parts of whey powder, 8-16 parts of meat of ampullaria gigas spix, 5-9 parts of an immunopotentiator, 2-4 parts of powder of medicinal stone 'maifanshi', 2-6 parts of compound stone powder, 2-4 parts of calcium dihydrogen phosphate, 0.8-1.4 parts of compound vitamins, 0.2-0.4 part of bacillus subtilis, 2-4 parts of olive oil, and 2-4 parts of Chinese herbalmedicines. The leech feed capable of improving water quality is low in raw material cost. The nutrients are matched in balance so that the leech feed is beneficial for digestion, absorption and growth-transformation of the leeches; moreover, the leech feed is capable of reducing N emission in metabolic wastes so as to ensure less organic residues in excreta, and thus, pollution to the growth environment of the water is reduced.
