Abstract

A species of Daphnia (water-flea), Moina macropa, was grown (under a dark-aerobic condition) using fresh cells of Chlorella ellipsoidea as a sole organic nutrient. After 45 hours of culture at 25° in the dark, the weight gain in Daphnia in percentage of the weight loss in Chlorella was found to be 30-33%, and the amount of nitrogen assimilated by Daphnia in percentage of the amount of nitrogen in Chlorella consumed was calculated to be 38-42%. These values were compared with some relevant data reported in the literature, and it was inferred that the culturing of Daphnia with Chlorella may probably be a most efficient syystem for coverting plant protein into animal protein.
