Red yeast Rhodotorula benthica – substitute feed base for echinoderms in factory cultivation

Abstract

Now decrease press of the fishery on natural populations of hydrobionts and restoration of their number due to artificial reproduction is actual. At artificial cultivation important properly to choose the right feed. To develop the feeding technology, work was carried out with larvae and juveniles of sea cucumber and gray sea urchin in the conditions of the mini-plant of the Scientific and Production Department of Mariculture of the Far Eastern State Technical Fisheries University located in Severnaya Bay (Slavyansky Gulf, the Sea of Japan) and Troitsa Bay (Vladimir Gulf, the Sea of Japan). Experimental studies have shown the possibility of using the sea yeast Rhodotorula benthica as either the main feed or as a feed additive. Practical recommendations have been developed for the use of Rhodotorula benthica yeast as a substitute feed base for growing larvae and juveniles of Japanese sea cucumber and gray sea urchin. The results of the work will serve as a basis for the development of biotechnology for feeding at echinoderm breeding farms and will be useful to the organizations, whose duties include rational and competent progress of marine economic territories.
