Embodiment 1

[0039] Prepare the dormant spore complexing agent for Nitzkiris microcrosterus for seawater culture of Penaeus monodon, and its formula is proportioned according to the following parts by weight:

[0040] In the present embodiment, take 1 part of dormant spores of Nitzschia minor, 0.30 part of ferric citrate, 10 parts of ferric chloride, 8 parts of sodium metasilicate, 0.60 part of disodium EDTA, vitamin B 12 0.10 parts; 80 parts of diammonium phosphate.

[0041] On-site production problem handling:

[0042] 1. Before applying the present invention, if the water color of the pond is found to be green, blue, red, etc., which indicates that other miscellaneous algae that are unfavorable to shrimp farming are proliferating in large numbers, the product of the present invention will not be applied temporarily. After killing these miscellaneous algae earlier, just use product of the present invention. If the pool water is already yellowish brown, apply it according to the transpa...

Embodiment 2

[0050] The present invention a kind of Penaeus monodon mariculture can replace the feed Nitzschia minor dormant spore compounding agent, its formula is proportioned according to the following parts by weight:

[0051] In the present embodiment, get 0.80 part of dormant spores of Nitzschia minor, 0.20 part of ferric citrate, 8 parts of ferric chloride, 6 parts of sodium metasilicate, 0.50 part of disodium EDTA, vitamin B120 .08 parts; 84.42 parts of diammonium phosphate.

[0052] The preparation method and technical conditions of the dormant spore complexing agent of Nitzschia minor are the same as in Example 1.

Embodiment 3

[0054] The present invention a kind of Penaeus monodon mariculture can replace the feed Nitzschia minor dormant spore compounding agent, its formula is proportioned according to the following parts by weight:

[0055] In the present embodiment 3, get 1.2 parts of Nitzschia minor dry powder, 0.40 part of ferric citrate, 12 parts of ferric chloride, 10 parts of sodium metasilicate, 0.70 part of disodium EDTA, 0.12 part of vitamin B12; 75.58 parts of diammonium phosphate.

[0056] The preparation method and technical conditions of the dormant spore complexing agent of Nitzschia minor are the same as in Example 1.

[0057] The present invention uses effect as follows:

[0058] In Qinzhou City, Guangxi, a pair of shrimp breeding ponds were tested, with an area of ​​6 mu and a water depth of 1 meter. The water quality was crystal clear before the seedlings were released. Put 24 kilograms of above-mentioned embodiment one compounding agent into the morning of the day before the see...

Abstract

The invention discloses a nitzschia closterium dormant spore ingredient for seaculture of a sugpo prawn and a preparation method thereof. The ingredient is prepared from matrix and nutrient medium; the matrix is a mixture of nitzschia closterium dormant spore, ferric citrate, ferric trichloride, sodium metasilicate, EDTA (ethylene diamine tetraacetic acid) disodium and vitamin B12; the nutrient medium is diammonium phosphate; and all the materials, except for the nitzschia closterium dormant spore, are crushed into 40 meshes and screened. The preparation method comprises the steps of mixing the following materials in parts by weight: 0.80-1.20 parts by weight of nitzschia closterium dormant spore, 0.20-0.40 part of ferric citrate, 8-12 parts of ferric trichloride, 6-10 parts of sodium metasilicate, 0.50-0.70 part of EDTA disodium and 0.08-0.12 part of vitamin B12, to prepare the matrix; packaging by a shading material, and then mixing 15.58-24.42 parts of matrix with 84.42-75.58 parts of nutrition diammonium phosphate to prepare the ingredient, packaging according to a specification of 10kg per bag, and warehousing. The nitzschia closterium dormant spore ingredient has a role in directionally breeding nitzschia closterium, and can replace seaculture feed of the sugpo prawn.

Description

technical field [0001] The invention relates to a dormant spore complexing agent of Nitzkiri crescentus for mariculture of Penaeus monodon and a preparation method thereof, belonging to the technical field of aquaculture. Background technique [0002] The taxonomic status of Penaeus monodon is: Arthropoda, Crustacea, Decapod, Swimming suborder, Penaeidae, and Penaeus. Penaeus monodon is called grass shrimp, bamboo shrimp, and monodon shrimp in China; it is called tiger prawn abroad. It is the main species of seawater shrimp farming in my country at present. [0003] Traditional aquaculture is mainly based on feeding feed, and now it has formed a huge production scale, supporting my country's status as the world's largest aquaculture country. However, with the continuous development and expansion of feeding and breeding production, the problem of the destruction of the natural environment has arisen. For example, red tides in coastal waters and algal blooms in inland water...
