Method for cultivating Perinereis aibuhitensis on desolate beach and capable of reducing Spartina alterniflora

Abstract

The invention discloses a method for cultivating Perinereis aibuhitensis on a desolate beach and capable of reducing Spartina alterniflora. The method includes the steps of firstly, selecting a flat and medium or high tidal-mud or silt beach rich in organic matter to serve as the cultivation site; secondly, transferring young Perinereis aibuhitensis which is cultivated in a pond and has 16-18 setigers to the beach for stocking, and adding young clams with the shell length being 1-2cm; thirdly, performing cultivation management, to be more specific, performing patrol inspection every day, entering the beach to inspect the growth condition of the Perinereis aibuhitensis when the beach is exposed, feeding special bait, arranging the surface of the beach, dredging draining ditches, removing enemies such as crabs, snails and fishes, draining accumulated water during the hot days in summer, and often observing the growth and development conditions of the young Perinereis aibuhitensis duringthe management at ordinary times, wherein the special bait is prepared by, by mass, 20.0-30.0 parts of peeled soybean meal, 10.0-20.0 parts of domestic fish meal, 5.0-10.0 parts of Siraitia grosvenorii extraction residue, 0.5-1.0 part of 4-D, 0.5-1.0 part of multivitamin and 0.5-1.0 part of composite mineral salt; fourthly, harvesting the 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 that can reduce the wasteland of Spartina alterniflora. Background technique [0002] Spartina alterniflora, belonging to Poaceae and Spartina, is a perennial herb that originated from the Atlantic coast of America and the Gulf of Mexico, and is suitable for living in the intertidal zone. Plants are resistant to salt and flooding, wind and waves, and seeds can spread with wind and waves. In the beach soil where the root system is distributed as deep as 60cm, a single plant can reproduce dozens or even hundreds of plants within a year. Because the straw of Spartina alterniflora is dense and thick, and its underground rhizomes are well developed, it can promote the rapid sedimentation and deposition of sediment. Therefore, many countries introduced it successively in the early 20th century in order to protect beaches and emban...

AI Technical Summary

Problems solved by technology

[0006] 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
