[0003] In the existing conventional microalgae culture nutrient solution components, such as NMB 3 Culture medium (Effect of unialgal diets on the composition of fatty acids and sterols in juvenile ark shell Tegillarca granosa Linnaeus, Journal of Agricultural and Food Chemistry, 60:3973–3980) and F / 2 medium (Guillard, 1975), mostly selected It is prepared by mixing certain inorganic salts and some vitamins. These nutrient solutions have certain advantages in the cultivation of microalgae in the laboratory, but these ingredients lack the organic nutrients needed for microalgae reproduction. The maximum reproduction density of the nutrient solution is not high enough to meet the bait demand for large-scale shellfish production; in addition, in the actual open-air algae culture ponds, these nutrient solutions are used to cultivate microalgae, and the plateau period is maintained for a short time. Feed it off, which is not conducive to the control of the amount of microalgae and the management of production in the process of large-scale shellfish production

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with examples. Both fish meal and shrimp meal can be selected from commonly used varieties in the feed field.
[0015] 1. Preparation of expanded culture medium
[0016] First, fish feed is prepared, which is composed of the following mass percentages: 52% fish meal, 17% shrimp meal, 9% corn meal, 8% flour, 8% soybean meal, and 6% brewer's yeast powder.
[0017] When preparing, take 520g fish meal, 170g shrimp meal, 90g corn meal, 80g flour, 80g soybean meal and 60g beer yeast powder and mix together, add water and mix, and use a granulator to make granules with a diameter of 1mm. Then take 2.5kg fish feed and add it to 25L seawater, stir it evenly, seal it in shading, soak it at 23°C for 24 hours, filter it through a 200-mesh nylon sieve (mesh diameter 75 μm) to obtain the fish feed soaking liquid, and store it in a plastic container in the dark. in the container.

Abstract
The invention provides amplified culture solution of marine microalgae, namely a self-produced granular eel feed of which the diameter is 1mm is selected as a culture liquid formula after being soaked and filtered by sea water, and then added to micro algae culture sea water to cultivate the marine microalgae. The cultivation result of the actual marine microalgae shows that the efficacy of the culture liquid provided by the invention is superior to the traditional common nutrition formula for cultivating the marine microalgae as to the final density of breeding of the marine microalgae or the maintaining time of a platform.
Description
technical field [0001] The invention belongs to the technical field of aquaculture bait cultivation, and in particular relates to an expanded culture solution of marine microalgae to improve the maximum reproduction density of the microalgae and the plateau period maintenance time. Background technique [0002] Marine microalgae are essential larvae bait in the breeding process of fish, shrimp, crab and shellfish seedlings in marine aquaculture. The scale of the cultivation industry is getting bigger and bigger, how to provide a sufficient amount of bait in shellfish production has become a problem that the industry needs to solve urgently. [0003] In the existing conventional microalgae culture nutrient solution components, such as NMB 3 Culture medium (Effect of unialgal diets on the composition of fatty acids and sterols in juvenile ark shell Tegillarca granosa Linnaeus, Journal of Agricultural and Food Chemistry, 60:3973–3980) and F / 2 medium (Guillard, 1975), mostly se...
