Abstract
The obtained data on the cultivation of chlorella in a nutrient medium containing macro and microelements based on local raw materials practically corresponds in terms of efficiency to the traditional Tamiya nutrient medium. Thus, innovative technology has been developed for obtaining an inexpensive, highly effective vitamin feed additive based on Chlorella vulgaris to replace artificial vitamins in fish feeding. The resulting water-soluble complex of macro and microelements makes it possible to completely replace expensive chemical elements in the cultivation of Chlorella vulgaris. Thanks to this, you can get an inexpensive vitamin-protein supplement for feeding fish. The presence of a full complex of natural vitamins in Chlorella vulgaris makes it possible to abandon expensive artificial vitamins when feeding fish. The effectiveness of which is only 5-10%, when natural vitamins are absorbed by 100%. All this reduces the use of expensive premixes that are added to fish feed.
