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 accordi...

Embodiment

[0030]A method for ecological restoration type tidal flat breeding clam worm and shellfish, comprising the following steps:

[0031] 1) Site selection: choose mid-high tidal mud or mud beach with relatively flat terrain and rich in organic matter, and build a long embankment at the lower part of the breeding area with a height of 10-20cm to prevent the loss of seedlings and escape. The beach surface is plowed before breeding , the plowing depth is 20cm, and the harmful organisms are removed at the same time. Fermented, dried and crushed pig manure and chicken manure are applied to the beach 3-7 days before the seedlings are placed, and organic fertilizer 3t / hm 2 , Before the clamworm seedlings are stocked, loosen and level the beach surface;

[0032] 2) Seed culture: cultivate ponds until 13-15 larvae are transplanted to the tidal flats for stocking, choose to carry out when there is a small amount of water on the tidal flat surface during low tide, and the stocking density is...

Abstract

The invention discloses a method for breeding perinereis aibuhitensis grub and shellfish on ecological remediation mud flat. The method includes the steps: 1) site selection: selecting middle-high tidal mud or sediment mud flat with flat terrain and rich organic materials; 2) seedling breeding: culturing setiger juvenile with 13-15 joints in a pond, transplant and releasing the setiger juvenile onthe mud flat, and releasing clam seedlings with the shell length of 1-2cm; 3) aquaculture management: performing patrol inspection every day, entering a beach face to inspect the growth state of theperinereis aibuhitensis grub when a beach is exposed, feeding special baits, arranging the beach face, dredging drainage ditches, removing crabs, snails, fishes and harmful organisms, completely draining accumulated water under hot weather in summer, and frequently observing growth and development states of young perinereis aibuhitensis grub in management at ordinary times; 4) adult catching. Thespecial baits are prepared from, by weight, 20.0-30.0 parts of corn gluten meal, 10.0-20.0 parts of steam fish meal, 5.0-10.0 parts of fructus momordicae extract residues, 0.5-1.0 part of 2, 4-D, 0.5-1.0 part of multi-vitamins and 0.5-1.0 part of complex mineral salt.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to an ecological restoration type tidal flat cultivation method for clam worms and shellfish. 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 inte...
