Salegentibacter mishustinae KCTC strain 12263 was isolated from the sea urchin Strongylocentrotus intermedius inhabiting the Sea of Japan. Here, we report the draft genome sequence of Salegentibacter mishustinae KCTC 12263. It comprises ~3.78 Mb in 38 contigs with a G+C content of 36.5%, and a total of 3,490 proteins-coding genes were obtained. One complete CRISPR-Cas gene cluster was identified in the genome, which shows the strategy against invasive genetic elements of the strain.

A novel marine bacterium, strain KMM 6050T, was isolated from the sea urchin Strongylocentrotus intermedius, which inhabits the Sea of Japan. The strain studied was strictly aerobic, heterotrophic, yellow–orange-pigmented, motile by gliding, Gram-negative and oxidase-, catalase-, β-galactosidase- and alkaline phosphatase-positive. The results of 16S rRNA gene sequence analysis showed that strain KMM 6050T occupies a distinct lineage within the family Flavobacteriaceae and is most closely related to the species Mesonia algae and Salegentibacter salegens (sequence similarity of 92·5–92·6 %). The DNA G+C content of KMM 6050T was 39·6 mol%. The major respiratory quinone was MK-6. The predominant fatty acids were i15 : 0, a15 : 0, 15 : 0, i16 : 1, i16 : 0, i16 : 0 3-OH and i17 : 0 3-OH. On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacterium has been assigned to the genus Gramella gen. nov., as Gramella echinicola sp. nov. The type strain is KMM 6050T (=KCTC 12278T=NBRC 100593T=LMG 22585T).

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.
