Embodiment 1

[0010] First of all, the cultivation of single-celled algae was carried out, and the cultivation of single-celled algae began in early March. The species used include Chaetoceros, Chrysalis, Isochrysis, Chlorella, and Pyramides. It is required to purchase newly isolated Algae species, to ensure the quality, use Kangwei liquid as nutrient salt to cultivate in the first-class bottle;

[0011] Carry out seedling breeding, go to the sea from June 20th to August 2nd to check the parental gonads of the cockles, every 3 to 7 days, and sample 1-2kg each time; harvest and transport the parental clams, when the parental gonads of the cockles develop rapidly When it is mature, it is required to harvest nearby, where there is no pollution from ships; temporarily raise the seed shells in a pool filled with seawater in the indoor nursery room, and the seed shells are temporarily raised at a density of 30-80 pieces / m 3 , the water depth is 80-150cm, put it in the net basket for temporary bre...

Embodiment 2

[0014] 1. Cultivation of unicellular algae

[0015] The cultivation of single-celled algae began in early March. The species used include Chaetoceros, Chrysoflagellates, Isochrysis, Chlorella, and Pyramides. It is required to purchase newly isolated algae species to ensure quality. Wei liquid is used as nutrient salt and cultivated in the primary bottle;

[0016] 2. Nursing

[0017] (1) From June 20th to August 2nd, go to the sea to check the gonads of clam species, once every 3 days, and sample 1kg each time;

[0018] (2) Harvesting and transportation of parent clams. When the gonads of clam clams are about to mature, it is required to collect them nearby, and to collect them in places where there is no pollution from ships;

[0019] (3) Temporary cultivation of seedling shellfish is carried out in a pool filled with seawater in the indoor nursery room, and the temporary cultivation density of seedling shellfish is 30-80 / m 3 , the water depth is 1m, put it in a net basket ...

Embodiment 3

[0029] 1. Cultivation of unicellular algae

[0030] The cultivation of single-celled algae began in early March. The species used include Chaetoceros, Chrysoflagellates, Isochrysis, Chlorella, and Pyramides. It is required to purchase newly isolated algae species to ensure quality. Wei liquid is used as nutrient salt and cultivated in the primary bottle;

[0031] 2. Nursing

[0032] (1) From June 20th to August 2nd, the clam seed glands were inspected, once every 7 days, and 2kg was sampled each time;

[0033] (2) Harvesting and transportation of parent clams. When the gonads of clam clams are about to mature, it is required to collect them nearby, and to collect them in places where there is no pollution from ships;

[0034] (3) Temporary cultivation of seedling shellfish is carried out in a pool filled with seawater in the indoor nursery room, and the temporary cultivation density of seedling shellfish is 30-80 / m 3 , the water depth is 1.5m, put it in a net basket for tem...

Abstract

A method of artificial breeding for ark shells, which includes cultivating unicellular algae first, then breeding, sampling and inspecting parent calms gonads of ark shells in the sea, capturing and transporting parent calms, breeding species shells temporarily in seeding room interiorly; spawning and hatching parent calms; selecting and breeding larvae, cultivating larvae, changing water once a day, scattering bait 30,000-100,000 / ml single cells every day; scattering cultch when the body length of larvae is 230 micrometers, changing water totally every day, moving larvae to the middle of the sea or shrimp tank to breed temporarily when the shells of them are 0.7-1.2mm; beating platform raft firstly as temporary breeding, the direction of which and flow direction being almost vertical; temporary breeding management, tying one hanging at intervals of 0.6-1.0m on every platform raft, 6-10 bags on every hanging, 5,000-15,000 juveniles shellfishes in every bag, arranging platform raft, promising the safety of platform raft, scattering on the bottom of the sea or cultivating in the shrimp tank when juveniles shellfishes grow up above 5mm. The advantage of the method can realize artificial breeding, short time of breeding, cultivation in the shrimp tank, bottom sowing in the sea and resume the population advantage, low-cast, quick results and great benefit.

Description

Background technique [0001] Commonly known as corrugated clam, it is a coastal bivalve mudflat shellfish. Its meat is delicious, rich in hemoglobin and vitamin B12, and has the effect of nourishing blood and invigorating the stomach. The market is in short supply and is deeply loved by the people. Clam seedlings mainly rely on their natural reproduction. In recent years, the output has dropped sharply and is facing extinction. At present, artificial breeding is still blank. Contents of the invention [0002] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, to provide a kind of indoor artificial nursery that can realize indoor seedling cultivation and the time for seedling cultivation is short, can not only carry out shrimp pond cultivation, but also can carry out sea area bottom sowing to increase resources, and can restore the population advantage and reduce the cost. The artificial seedling raising method of cockles ...
