The present invention provides chlorophyll-rich and salt-tolerant chlorella which contains a large amount of chlorophyll, and which makes it possible to supply cultured fishes with little contamination with environmental contaminants such as dioxin or the like having been concentrated through the food-chain from seawater when used as feeds for rotifers for pisciculture, and which can survive a long time in seawater and, consequently, which is suitable for feeds for sea surface pisciculture, fishery feeds and the like. Chlorophyll-rich and salt-tolerant Genus Chlorella mutant strain which can grow in a medium containing 1% by weight or more of sodium chloride and contains chlorophyll at a concentration of 4% or more in total on the basis of dry matter can be constructed by conducting a mutation treatment with a plurality of UV-irradiation and a mutation treatment with a mutagen such as methanesulfonic acid ester, acriflavine or the like. |
