Cultivation of the diatom algae Chaetoceros calcitrans f. pumilus (Paulsen) Takano, 1968 as food for giant oyster larvae Crassostrea gigas (Thunberg)
An impact of modified nutrient media F/2 and Conway on the growth and biomass accumulation of the diatom algae Chaetoceros calcitrans f. pumilus, which is a part of the food for cultivated larvae of the giant oyster Crassostrea gigas in the IMBR RAS nursery, was studied. Maximum values of cell and b...
