Method of Culturing Freshwater Diatom and Algae for Early Marsh Snail Juveniles

摘要

The present invention relates to a method for increasing the growth rate and survival rate of the seedlings produced by cultivating the freshwater algae, which is a food organism of the seedlings, in accordance with the initial growth period of the seedlings. The present invention adjusts the light conditions when culturing freshwater algae, which is a prey organism for the initial seedling of Daseulgi, so that more freshwater algae are cultivated, and the kind and constituents of the cultured freshwater algae are suitable for the initial growth process of the seedling. , It is possible to increase the growth rate and survival rate of freshwater algae by differentiating the growth substrate from which freshwater algae and seulgi plaques are attached and the culture substrate for preliminary attached algae.
