In the previous study of the Antarctic krill, Euphausia superba meal was observed to enhance growth in some cultured fishes. The non-muscle krill meal was further investigated using column chromatography on silicic acid, Sephadex LH-20 gel filtration and preparative thin layer chromatography (TLC) successively in three steps, in order to clarify the factors promoting growth. The sub-fractions and elution obtained at every step were supplemented in test diets and tested for growth effect in fingerlings of red sea bream Chrysophrys major. At least three elutions that showed growth activity were separated and they were clarified through further tests as steroidal in nature.
