According to the data of trawl catches performed by the R/V “TINRO” in the upper epipelagic zone (0–50 m) of Pacific waters off the Kuril Islands from June 2 to July 8, 2012, the abundance of nekton was the lowest for the recent 9 years; thus, its density in 2012 (1.5 t/km2) was lower than the average value for the 2004–2012 period (2.40 ± 0.39 t/k...

The mortality of Sea of Okhotsk pink salmon in the winter and spring varies significantly from year to year, which complicates forecasts of its arrival in the following year based on data on the downstream migration of fry and surveys in the fall. The size-selective mortality of pink salmon was studied and the possibility of using the size and weig...

The study of the biology of the mud shrimp Upogebia issaeffi (Balss, 1913) from the subtidal zone of the Vostok Bay (Peter the Great Bay, Sea of Japan) revealed that this species occurs at depth of 1–6 m on mixed grounds of boulders, gravel, pebbles, shells of dead clams, and silty sand. The average population density of U. issaeffi in the local ag...

Using immunohistochemistry, we examined the distribution of the hydrogen sulfide (H2S) synthesizing enzymes cystathionine β-synthase (CBS) and cystathionine Γ-lyase (CSE) in tissues of the nemertean Cerebratulus marginatus Renier, 1804 (Heteronemertea: Lineidae). The expression of both CBS and CSE was found in the body wall and in the receptor cell...

The results of a study of diatoms from surface sediments (0–1 cm) of Amurskiy Bay are presented for the first time. The specific composition (221 species and intraspecific taxa) and ecological structure of the diatom flora were determined. The diatom species composition of phytoplankton, periphyton, and surface sediments is compared.

Based on our own and current literature data, we analyzed the prebiotic properties of polysaccharides and extracts of seaweeds. The role of prebiotics, particularly polysaccharides, in the normalization of intestinal microflora is discussed; consideration is also given to the possibility of seaweed polysaccharide fermentation by colonic microflora ...

Ciliary and nerve structures were described in juvenile female Dinophilus gyrociliatus (O. Schmidt, 1848) after immunochemical staining with tubulin, serotonin, and FMRFamide antibodies. Anti-tubulin antibodies revealed the following external structures: two head and seven body ciliary bands, a ventral ciliary band, and head ciliary fields. Gut cil...

The impacts of different concentrations of the excretory-secretory products (ESPs) of the solitary ascidian Styela rustica (Linnaeus, 1767) and the sponge Halichondria panacea (Pallas, 1766) on the settlement, metamorphosis, and mortality rates of H. panacea larvae were studied in a laboratory experiment. At high concentrations, substances released...

Invertebrates from the Sea of Okhotsk were studied as a source of proteins that are capable of binding to lipopolysaccharides (LPSs) of gram-negative bacteria. A DOT analysis using dansyl-labeled LPS that we developed revealed LPS-binding proteins in blood-cell lysates of 21 out of 33 investigated species of invertebrates. Most of the investigated ...

The Wnt5 protein localization in holothurian Eupentacta fraudatrix tissues was examined in the norm and during regeneration. In healthy E. fraudatrix, Wnt5 was found in solitary cells of the hypodermis and in the radial nerve cords. During regeneration, the number of Wnt5 positive cells increased. They were observed in the connective tissue of the ...
