Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the shellfish seedlings cannot provide the nutrients needed for growth due to the living algae bait in the shellfish seedling raising process existing in the prior art The invention provides an algae powder-type seedling-raising bait and its application and a method for artificially raising shellfish seedlings. Utilizing the algae-flour-type seedling-raising bait to raise shellfish seedlings can improve the growth and development requirements of shellfish seedlings, and improve the emergence rate and activity of shellfish

preparation example Construction

[0048] In a preferred embodiment of the invention, the preparation method of the chroma powder comprises: freeze drying or spray drying, respectively.

[0049] Preferably, the freeze-dried method comprises pre-freezing 1-4 h under the conditions of -40 to -30 ° C, sublimated at a temperature of from -20 to 0 ° C for 15-24 h, under 20-40 ° C. Secondary analysis 1-6h.

[0050] Preferably, the spray drying conditions comprise: the air intake air temperature is 150-200 ° C, the air supply temperature is 85-95 ° C, and the time is 36-54 h.

[0051] Among them, the preparation method of the oliginal seedlings can be to mix uniform in proportion in ratios.

[0052] In one embodiment of the invention, the algae powder seedling bait comprises at least two of triangular brown gas algae, algae, and algae; wherein the total weight of the gravesty seedling bait is used. The content of the triangular brown gas algae is ≤10% by weight (such as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10% by weight, and any...

Abstract

The invention relates to the field of cultivation, in particular to algae powder type breeding bait, application thereof and an artificial shellfish breeding method. The algae powder type breeding bait A comprises at least two of chlorella, phaeodactylum tricornutum, chrysophyceae, chaetoceros and platymonas subcordiformis; wherein the content of chlorella is less than or equal to 40 wt%, the content of phaeodactylum tricornutum is less than 100 wt%, the content of chrysophyceae is less than 100 wt%, the content of chaetoceros is less than or equal to 60 wt%, and the content of platymonas subcordiformis is less than or equal to 20 wt% based on the total weight of the algae powder type breeding bait A. By adopting the algae powder type breeding bait, the emergence rate of spats in a sea area can be increased by nearly two times, the vitality of the spats is improved, and the capability of coping with environmental changes is improved.

Description

Technical field [0001] The present invention relates to the field of breeding, and more particularly to a method of percolite seedling bait and its application and shellfish artificial nursery. Background technique [0002] Now the culture of shellfield single cell live algae is generally carried out in a bucket and cement pool, and the cultivation of live algae is carried out in a bucket and cement pool in an outdoor open environment. The growth of algae cells is affected by the climate environment, water body The environment affects, the number and quality of algae cells fluctuate with the fluctuations of the climate environment and water environment, resulting in the quantity and quality of the shellfish bait. The live algae in the shellfield is cultivated by the pollution caused by the climate, the environment, the environment, and the floating animals, and the failure of live algae, and only single live algae seedlings are used in most cases. Due to the problem of the number...
