Experimental larval rearing of the Japanese sea cucumber in a mini plant in Severnaya bay (Slavyansky bay, Sea of Japan) was carried out. The experiment did not reveal any relevant difference in time or speed of reaching different larval development stages or survival rate of the sea cucumber either with the diet supplemented with pigmented yeast Rhodotorula benthica or when fed with the Chaetoceros muelleri and Dunaliella salina phytoplankton. In the lack of the traditional phytoplankton-based fodder, it appears relevant and feasible for the aquaculture enterprises to use such fodder replacement options as Rhodotorula benthica marine pigmented yeast, a non-pathological species with low production cost that does not require any sophisticated cultivation techniques, easy to use and generally yielding a highly predictable production result.
