Problems solved by technology

However, in the cultivation process of shellfish-eating algae, it was found that the harmful protozoa (ciliates, abdominal caterpillars, amoebas, etc.) were not effectively controlled by using the existing culture medium (medium), and at the same time, the growth of shellfish-eating algae was not effectively controlled. Recovery has no obvious effect, so how to achieve the purpose of killing harmful protozoa by adjusting the pH of the culture medium (culture medium), and at the same time, how to quickly recover and grow microalgae has become a technical problem that needs to be solved urgently

Abstract

The invention belongs to the technical field of algological biology. In view of defects in the prior art, the invention provides an algae filament resuscitation fluid for shellfish feeding microalgae,which is characterized by comprising the following components in parts by weight: 500-1000 parts of potassium nitrate, 500-1000 parts of potassium dihydrogen phosphate, 200-300 parts of ethylene diamine tetraacetic acid, 100-200 parts of ferric trichloride, 100-200 parts of sodium bicarbonate, 10-20 parts of vitamin B1, 10-20 parts of vitamin B12, 2-5 parts of trace elements and 1500-2000 parts of distilled water. The algae filament resuscitation fluid for the shellfish feeding microalgae provided by the invention is safe and reliable, has no adverse effect on the growth of the shellfish feeding microalgae, avoids the waste of a culture solution caused by algae pollution, and effectively reduces the production cost of the shellfish seedling industry.

Description

technical field [0001] The invention belongs to the technical field of algae biology, and in particular relates to an algae species resuscitation liquid for shellfish feeding on microalgae. Background technique [0002] Shellfish need to take in a lot of nutrients in the process of growth and development, and mainly rely on the intake of nutrients from microalgae to maintain growth. hot issues of concern. Although the traditional algae-feeding medium can guarantee the basic nutrients for shellfish growth, it cannot ensure the growth and reproduction efficiency of algae, and is easily affected by miscellaneous algae and diseases, causing algae pollution. [0003] CN102093957A discloses a high-fat chlorella culture solution for rapid growth promotion. It contains bamboo acetic acid 1-8%, main nutrient 4-15%, micronutrient 0.2-2.5%, soil extract 0-1.5%, water 78-94%, and described main nutrient is sodium nitrate, One or more mixtures of dipotassium hydrogen phosphate, potass...
