1, prevent escape. To escape against the walls of the pond, the wall is 80-90 cm high, and the underground part is more than 30 cm. The inside of the wall is plastered with cement and sand to form a sloping surface (the smoother the water wall is, the easier it is to escape).
2, more than aquatic plants. Water hyacinths and duckweeds are predominant. Water hyacinths are afraid of direct sunlight. Water hyacinths and duckweeds are both feed for snails and shading for otter. Otters can also lay eggs on them.
3, invest enough snails. The snail should choose large size. In addition, blood clots of livestock and poultry are released once a week for the leeches, but the blood clots cannot contain salt. In order not to affect the water quality, blood clots can be placed on wooden boards to make them float on the water. Blood clots should not be stored for more than two days.
4. After the introduction, do not put the otters into the pond directly. Because the leeches themselves will produce a layer of mucus as a protective layer during transportation, the leeches should first be placed in a cool, damp place around the pond so that the otters can naturally climb into the pond to reduce death.
5, to maintain the right water level. The otters reproduce in the soil under the cover, not in the water. During the breeding season, if the water passes through the soil bed for about 7 days, the mink eggs will die due to lack of oxygen. Care should be taken to maintain a suitable water level to ensure successful breeding.
6. Grading treatment: The leeches are separated by large, medium, and small. The large culls are selected and put back into the pond to be preserved as seed pods. The larvae are kept small in another pool to continue raising. Medium, processed immediately into dry products for sale.
7. Fertilizers and pesticides cannot be applied during the cultivation of mink.
The Fluorochemicals compound is a new field in modern organic chemistry. It has a special physical and chemical properties, so it is widely used in the earliest development of applied pesticides and rat poison. During World War II it was developed in some countries appliedas antimicrobial agents, there are more and more new research suggests that fluorochemical will play an increasingly more important role in the field of anticancer drugs. We started later in the field of fluorochemicals, but we have a strong sense of his enormous potential, and we are increasing investment to catch up. We will custom product which has potential market prospects from gram and kilogram-class through process optimization, enlarged to the size of ton. Currently we have developed more fluorochemical compounds in the benzoic acid range, the number of products have been more than 2017.
