A kind of intensive production method of indoor double-toothed clamworm seedlings

Abstract

The invention discloses an indoor intensive production method of perinereis aibuhitensis seeds, belonging to the field of aquaculture. The method comprises the steps of preparing a cement pond, preparing mud for culturing, preparing perinereis aibuhitensis culture boxes, distributing larva seeds, breeding the seeds, daily managing and enabling the seeds to emerge. In the cement pond, the multiple layers of small perinereis aibuhitensis culture boxes are arranged in a staggered stacking way, the attachment surface area of larvae in the cement pond can be increased, indoor intensive high-density production of the perinereis aibuhitensis seeds is realized, the seed output of the cement pond of a unit water body is increased, outdoor earth pond culture is not needed, the seeds with the large size of 20 to 30mm are directly obtained, and large-scale intensive production of the seeds is realized; if the perinereis aibuhitensis seeds are sold or broadcast remotely, the perinereis aibuhitensis seeds can be conveyed with the boxes and soil, convenience and quickness are realized, and damage caused in the collection, transfer and conveying processes of perinereis aibuhitensis larvae is avoided.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an indoor intensive production method for clam worm seedlings. Background technique [0002] Perinereis aibuhitensis belongs to Annelida, Polychaete, Migratory Order, Nereistae, and Perinereis genus in taxonomy. It is widely distributed in the coastal intertidal zone of my country. The dominant species of beach organisms, P. bidentata, has a strong tolerance to pollution, has a strong indicator effect on environmental changes, and also has the effect of improving the bottom quality of the intertidal zone. It mainly constitutes organisms and has important ecological value. [0003] Nereist worm is an excellent bait and bait for sea fish, shrimp, and crabs. It is rich in nutritional value and has extremely high economic value. It is a key aquatic product that is cultivated in my country and exported to foreign countries. The body is rich in proteins, amino acids, vitamins, tra...

Problems solved by technology

When the larvae grow to 10-12 knots, they need to be put into earthen ponds for subsequent cultivation of seedlings. However, the collection and transfer of 10-12 ganglion larvae will also cause seedling damage and death, which greatly affects the The survival rate of clam worm seedlings; and using this technical method, if the clam worm seedlings are collected, transported and sold, it is easy to cause damage and death of the clam worm seedlings, and at the same time consume a lot of manpower and material resources, which greatly limits the Large-scale production and product sales of double-toothed clamworm
