Problems solved by technology

However, the drug particles are uneven, most of the drugs sink to the bottom of the water and gradually dissolve in the water, and cannot be ingested by planktonic larvae; although drug particles below 20 μm can be ingested by some planktonic larvae, the amount of drug ingested by the larvae has far exceeded its suitable Dosage, after the larvae eat the drug, there are usually serious adverse reactions such as stopping feeding within 1 to 2 days, slowing down the growth rate, and uneven growth of the larvae

Embodiment 1

[0022] 1. Inactivation of baker's yeast: put the baker's yeast in a sterilizing pot at 100-120°C for 10-15 minutes;

[0023] 2. Drying of baker's yeast: put the above-mentioned inactivated baker's yeast in a constant temperature drying box and dry at 60-70°C for 1-2 hours, and set aside;

[0024] 3. Preparation of tetracycline solution: put 1-2g tetracycline tablet in 100ml of fresh water, soak to disintegrate the tablet, and let it stand for 1-2 hours to completely dissolve tetracycline, discard the precipitate, and finally prepare a concentration of 1-2%. tetracycline aqueous solution.

[0025] 4. Introduction of tetracycline into baker's yeast: Weigh the inactivated and dried baker's yeast according to 0.05-0.3 parts per million of the weight of the seedling water body, and place it in a small beaker; then pour the prepared tetracycline aqueous solution into the beaker, the amount of which is It can fully submerge the bread yeast. Mix and soak for 30-60 minutes, and the t...

Abstract

The invention provides a pinctada maxima planktonic larva administration method. An antibacterial medicament is introduced into bread yeast with good palatability for pinctada maxima planktonic larva by taking the measures of increasing the permeability of bread yeast cell membranes, soaking the antibacterial medicament into aqueous solution and the like; and the pinctada maxima planktonic larva takes the medicament at the same time of taking the bread yeast. By adopting the method, the medicament taking efficiency of the pinctada maxima planktonic larva is high, toxic or side effect is not caused by excessive medicament, and the disease preventing effect is good.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for administering planktonic larvae of Pinctada maxima. Background technique [0002] Seawater pearl cultivation is a characteristic industry in my country. The cultivated varieties include Martensii pearl oyster pearls (South pearls), large pearl oyster oyster pearls (South Sea pearls), black butterfly oyster pearls (black pearls) and penguin oyster oyster pearls. Mother-of-pearl pearls (South Sea pearls) are the most valuable pearls in the world. Due to the degradation of germplasm and the aging of sea areas, the traditional pearl industry in my country has gradually declined, and the pearl varieties that cultivate high-grade seawater pearls, such as Pinctada maxima, have attracted more and more attention. At present, my country's large-scale pearl oyster artificial seedlings can be produced on a large scale, but there are still problems of artificial seedling inst...
