The establishment of simple attachments to the trophozoites of four shrimp ponds of sea cucumber aquaculture technology

In recent years, shrimp farmers have transferred their shrimp ponds to other disease-resistant varieties such as fish, shellfish and sea cucumber. Among them, sea cucumbers have the highest benefits, and the aquaculture area has expanded year by year.
Shrimp pool to raise the sea cucumber, we must first solve the problem of attachments, for this reason, some shrimp farmers throw stones into the shrimp ponds to create artificial reefs; some do not hesitate to set the corrugated plate. The above measures not only increase investment pressure, but also increase the difficulty of clearing ponds for the recovery of shrimps. In order to resolve these contradictions, the authors recommend the following simple methods for artificial attachments:
1. Fill the woven bag with sand and tie the mouth tightly so that the diameter can reach 30cm or more.
2. According to the distance between 2m and 3m, arrange along the deep-water zone of the pool and require all the sandbags to be in the same plane. The total arrangement area accounts for 1/3 of the bottom area of ​​the shrimp pond.
3. Cut a 0.18mm black plastic film into 80cm wide strips, and cut out randomly distributed round holes with a diameter of 1cm to 2cm. The area of ​​the round holes accounts for about 20% of the area of ​​the film, and it is laid flat on the sandbags. .
4, the plastic film with sandbags in the sandbags on the lower layer of the firm, and then spread the second layer of sandbags on the second layer, the general depth 1.6m above the shrimp pond, set up three layers of plastic film is appropriate.
After the above transformation of the shrimp pond, raising the ginseng is easy to manage, good feeding, it will be collected, each seedling can be put 1cm ~ 2cm seedlings 10000, the average film distribution per square meter 15 head, harvest 2000 to 2500 per acre, The individual is generally 150g.
Afterwards, it will resume shrimp rearing, receive net sea cucumbers, cut sandbags, and remove the thin film.
