SELENIUM-CONTAINING UNICELLULAR MICROALGAE FOR ANIMAL PLANKTON FEEDS AND METHOD OF CULTURING SELENIUM-CONTAINING ANIMAL PLANKTONS USING THE SAME

摘要

Based on the finding that no or very little selenium is detected in animal planktons which are cultured by the existing method, it is noticed that there is a possibility that marine larval fish at the stage of taking these biological feeds would suffer from selenium deficiency. Selenium-containing animal planktons can be successfully produced by developing a method of producing selenium-containing animal planktons, preliminarily incorporating selenium into unicellular microalgae, and culturing animal planktons with the use of the unicellular microalgae as a feed. Thus, the survival rate and vitality of larval fish having been deficient in selenium can be remarkably elevated.
