Method for breeding perinereis aibuhitensis grube and shellfishes by ecological restoration type tidal flat

Abstract

The invention discloses a method for breeding perinereis aibuhitensis grube and shellfishes by an ecological restoration type tidal flat. The method comprises the following steps: (1) site selection:selecting a medium and high wattenschlick or silt tidal flat which has flat terrain and is rich in organic matters; (2) juvenile breeding: breeding and culturing to 13-15 setiger juveniles in a pond,transferring the setiger juveniles to the tidal flat for stocking, and throwing clam juveniles of which the lengths of shells are 1-2 cm; (3) breeding management: carrying out patrol inspection everyday, entering a beach face to examine growth conditions of clam worms when the beach is exposed, feeding the clam worms with special baits, neatening the beach surface, dredging a drainage ditch, removing crabs, snails, fishes and enemy organisms, completely draining accumulated water in hot days in summers, and frequently observing growth development conditions of the clam worm juveniles during management at ordinary times, wherein the special baits are prepared from the following components by mass: 20.0-30.0 parts of corn gluten meal, 10.0-20.0 parts of corpesca, 5.0-10.0 parts of passion fruit residues, 0.5-1.0 part of 2,4-D, 0.5-1.0 part of multivitamins and 0.5-1.0 part of composite mineral salt; and (4) fishing and catching adults.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a method for cultivating clam worms and shellfish in ecologically restored tidal flats. Background technique [0002] The clamworm belongs to the general designation of some economic clamworm species of the phylum Annelida, polychaete, wandering order, clamworm family, perinereis (Perinereis) and thorn clamworm (Neanthes), commonly known as "sea leech", "sea leech" and "sea leech". Centipede". The main species are double-toothed nereis, occipital-toothed nereis and so on. The body is clearly segmented, and the two sides of the body segment protrude into warped feet with bristles for movement. About 10 cm long. 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...

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
