Mink, also known as leech, is used to dry all medicine. Due to the destruction of wild resources, its prices have increased, and the current purchase price of production areas is 60 to 110 yuan/kg. It is a simple project to raise aquaculture, and it is a good project for small investments. Breeding leeches should pay attention to the following issues.
1. Pay attention to avoidance of flight: Make sure to escape from the wall at the perimeter of the pond. The height is 80 to 90 cm. The inside of the wall is plastered with cement and sand.
2. A large number of aquatic plants are stocked: mainly water hyacinth and duckweed. The otters are afraid of direct sunlight, so a large number of aquatic plants can be used as a feed for snails and shading, and otters can also lay eggs on them.
3. Supply sufficient feed: About 50 kg of snail should be put into every 667 square meters of water. In addition, a blood clot of livestock and poultry should be given once a week for the leeches, but the blood clots must not contain salt. In order not to affect the water quality, blood clots cannot be directly put into water. The blood clot can be placed on the block so that it floats on the water. After the leeches smell the odor, they can climb up to eat. The blood clots should not be placed in excess of two days.
4. The leeches should not be put into the pond directly after introduction: because the leeches themselves will produce a layer of mucous membrane as a protective film during transportation. You should choose a cool, damp place around the pond, put the otters inside, and let them climb into the pond to reduce death.
5. Observe: The otters are in the soil under the cover, not in the water. During the breeding period, if the water passes through the soil bed for about 7 days, the mink eggs will die due to lack of oxygen. Therefore, attention should be paid to inspection to ensure the success of breeding.
6. Timely capture: The capture period is generally in October. The leeches recovered are separated by large, medium, and small. The large ones are screened out and put back into the pool to be left as water pods; the small ones are placed in a pool to continue cultivating, so that they can be salvaged and sold when they are raised to more than 15 grams in the second year; the medium ones should be processed into dried products and sold immediately.
