The method is characterized by comprising the following steps: (1) carrying out preparation work; (2) inoculating; (3) carrying out carpospore release; (4) germinating and attaching carpospore; (5) collecting conchospore seedlings. The large-scale seedling breeding method for porphyra yezoensis, provided by the invention, has the technical effects of being suitable for actual situations, having relatively strong operability and being very broad in popularization prospect.

Description

Porphyra yezoensis seedling method for scaled breeding

Technical field

the present invention relates to a kind of porphyra yezoensis seedling method for scaled breeding, belong to technical field of aquaculture.

Background technology

china is main laver producing country of the world, about wherein the porphyra yezoensis output value accounts for the half of China's laver total value.Current China porphyra yezoensis has formed comparatively complete industrialization system such as kind of a matter seedling fostering, cultivation, circulation and processing and relevant device manufacture etc.But along with production-scale continuous expansion, the problems such as the such as kind matter that porphyra yezoensis industry faces is degenerated, disease takes place frequently, the mode of production falls behind become increasingly conspicuous.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art part, a kind of porphyra yezoensis seedling method for scaled breeding is provided.

Porphyra yezoensis seedling method for scaled breeding of the present invention, comprises the steps:

The first step: preparation

1) pollution-free, to extract seawater convenience, traffic convenience seedling rearing room is prepared;

2) clean nursery pond is prepared

3) clean sedimentation basin is prepared

4) clean shell is prepared: select fresh, unworn clam shell, scrape black removal ligament, remaining muscle and shell membrane, after cleaning up, shell is neatly discharged at the bottom of nursery pond in squamous behind north orientation south by size stepping, then add precipitation seawater 15-20cm, stand-by;

Second step: inoculation

Precipitation seawater is first injected in nursery pond, selection streak feature is obvious, frond bright in color, healthy and strong parent for planting vegetables, more neatly will discharge at the bottom of pond in squamous after shell by size stepping, and the kind algae seawater selected is cleaned, the kind algae that gauze will dry in the shade, wraps and saves backup at low temperatures;

3rd step: carpospore is diffused

The kind algae of drying in the shade directly is put into the cylinder filling precipitation seawater and diffuses, and constantly stirs seawater in diffusing, and take out kind of an algae after 1-2 hour, filtered through gauze spore liquid, is evenly sprayed to spore liquid on shell;

4th step: the sprouting of carposporophyte and attachment

Cultivate under natural temperature, irregularly measure nursery pond maritime interior waters proportion and pH value, add seawater, inoculate latter 15 days-20 days and carry out first time and scrub shell, later interval scrubs 1 time in 15 days-25 days, should avoid the dry dew of shell and damage when scrubbing;

5th step: conchospore is collected seedling

It is exactly that conchospore that shell is released is captured on lace curtaining that conchospore is collected seedling, concrete operation method: by lace curtaining uniform spreading to collecting seedling in pond, to often stir in water-rinsing process, draw even, exchange lace curtaining.

Porphyra yezoensis seedling method for scaled breeding of the present invention, has following technique effect:

Be applicable to actual conditions, have stronger operability, promotion prospect is very wide.
