To facilitate the mass larval rearing of cold water (<10°C) marine fish and crustacean species, the cultivation of their live food organisms at similar water temperatures is desirable. A parthenogenetic strain of the rotifer Brachionus plicatilis, fed on Chlorella saccharophila and previously cultured continually at 20°C, was acclimated for 1 year at a constant temperature of 10°C. Variations in body size, individual and population growth rates, and reproductive rate were observed at these two temperatures. This strain of B. plicatilis exhibited slower growth and development rates, reduced reproductive rates, longer life-span, and larger body size at the lower acclimation temperature. Parthenogenetic reproduction remained persistent throughout the acclimation period, with no appearance of mixis. Despite slower growth and reproductive rates, resulting in an extended culture period, maximal population densities and net reproduction were similar at both acclimation temperatures.
