Vegetal bait culture method

Abstract

The invention relates to a vegetal bait culture method. Algae seeds carry out primary and secondary culture, the culture used seawater carries out sterilization treatment, the primary culture lasts 7 to 10 days, and steps for adding nutrient salt kangwei ingredients into per 100 mL materials are as follows: preparing first solution with the following ingredients by weight ratio: 50g of ferric trichloride, 1.8g of manganese chloride, 168g of boric acid, 225g of tetrasodium ethylenediamine tetraacetate, 100g of monopotassium phosphate and 500g of sodium borate; preparing second solution with the following ingredients by weight ratio: 0.5g of zinc butter, 0.5g of cobalt chloride, 0.25g of ammonium molybdate and 0.5g of bluestone; pouring the second solution into the first solution; adding vitamin B1 and B12; carrying out secondary culture for 0.5 to 1 month; and maintaining the air inflation, wherein the added culture mother solution comprises the following ingredients by weight ratio: 50g of sodium nitrate, 5g of monopotassium phosphate, 0.5g of ferric ammonium citrate and 100ml of disinfected seawater. When the vegetal bait culture method of the invention is adopted, the production cost can be lowered, and the yield can be improved.

Description

technical field [0001] The invention relates to a live bait in mariculture production, in particular to a plant bait cultivation method. Background technique [0002] A large number of artificially cultivated algae are used as a source of live bait for marine animal larvae. The bait is one of the keys to the success of seawater seedlings. It not only directly affects the growth and reproduction of the seedlings, but also may be decomposed with residual bait and excrement under high-density culture conditions. Corrupt water quality, affect the growth and reproduction of seedlings, resulting in an increase in production costs. Therefore, in order to further solve the bait problem of marine economic animal breeding, it is necessary to improve the cultivation method and improve the cultivation effect. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a plant-based bait culture method that reduces production costs while...
