Breeding method of perinereis aibuhitensis

Abstract

The invention discloses a breeding method of perinereis aibuhitensis. The method includes the steps of (1) field selection; (2) larva breeding; (3) breeding management, wherein when perinereis aibuhitensis grows to 3-5 cm in length, perinereis aibuhitensis is fed with a special bait, seawater is put into a pool before feeding, after perinereis aibuhitensis is soaked in the pool for half an hour, the seawater is drained out to simulate a rising tide and a falling tide, then feeding is conducted, the simulation of the rising tide and the falling tide is carried out twice a day, and the special bait is prepared from, by mass, 20.0-30.0 parts of bean pulp without peels, 10.0-20.0 parts of domestic fish meal, 5.0-10.0 parts of siraitia grosvenorii extract dreg, 0.5-1 part of 2,4-dichlorophenoxyacetic acid, 0.5-1 part of compound vitamin and 0.5-1 part of compound mineral salt; (4) capture of adult perinereis aibuhitensis.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a method for cultivating clam worms. Background technique [0002] Perinereis aibuhitensis belongs to the phylum Annelida, polychaetes, Nereidae, and the genus Perinereis. Its body is bilaterally symmetrical and segmented long columnar, composed of many segments. Commonly known as sea entertainment clam or sea leech. The clam worm is benthic and scavenging, and is an important species in the food chain of the marine ecosystem. It is also a high-quality bait for marine small animals and large animal larvae, and is widely used in aquaculture production and fishing fisheries. Nereis didentate is a species that likes to be distributed on soft substrates in middle and high tide areas. It is the main species in the marine natural ecological system. A high-quality bait for marine fish, shrimp and crab in the intertidal zone, a kind of animal bait, is the main bait f...

AI Technical Summary

Problems solved by technology

[0005] The cultivation of clam worms relies on natural bait alone, which cannot maintain the growth and development of clam worms. In addition to causing self-mutilation and sparseness, it will also cause the nurturing individuals to be small and difficult to meet the requirements of commercial products.

In the prior art, as for clamworm bait, there is no special formula and synthetic bait at present, only according to its individual size and feeding habits, self-selection, such as the basic bait for fertilization and reproduction in the early stage (larval stage), gradually increase Fishmeal, soybean meal and other powder baits, in the middle and late stages (growing stage), the small miscellaneous fish and shrimps caught by the net are crushed and beaten or the soybean meal is crushed, sprinkled with water, and fed frequently
