Abstract
Milky hemolymph syndrome (MHS) caused by a bacilliform virus (BV) was found in tanner crab Chionoecetes bairdi in the shelf zone of Kamchatka. The prevalence of the disease varied from 0.18 to 1.02%. A total lesion of the cells of the interstitial connective tissue and the connective tissue component of all internal organs was noted, which was expressed in the hypertrophy of their nuclei. In addition, hypertrophy of fixed phagocytes and circulating hemocytes was noted. Ultrastructural analysis of the tissues confirmed that in the interstitial connective tissue of pathologically altered organs, virus particles of two morphotypes were found - rod-shaped and globular. In the cytoplasm of infected cells, bands of microtubules formed near where viral particles were concentrated. In the area of contacts at the poles of microtubules, successive stages of the transformation of rod-shaped viruses into globular viruses was observed. The bacilliform virus that infects C. bairdi is structurally very similar to CoBV found in Chionoecetes opilio. Structural features are characteristic of representatives of fam. Nimaviridae. The molecular data obtained suggest that the virus causing MHS in C. bairdi is systematically very close, if not identical, to CoBV.

Abstract
Selenium (SeNPs) and tellurium nanoparticles (TeNPs) were synthesized by green technology using the three new bacterial marine isolates (strains PL 2476, AF 2469 and G 2451). Isolates were classified as Pseudoalteromonas shioyasakiensis according to 16S rRNA sequence analysis, morphological characteristics, and biochemical reactions. The bioreduction processes of isolates were studied in comparison with the previously described Alteromonas macleodii (strain 2328). All strains exhibited significant tolerance to selenite and tellurite up to 1000 µg/mL. A comparative analysis of the bioreduction processes of the isolates demonstrated that the strains have a high rate of reduction processes. Characterization of biogenic red SeNPs and black TeNPs using scanning electron microscopy (SEM), EDX analysis, Dynamic Light Scattering, and micro-Raman Spectroscopy revealed that all the isolates form stable spherical selenium and tellurium nanoparticles whose size as well as elemental composition depend on the producer strain. Nanoparticles of the smallest size (up to 100 nm) were observed only for strain PL 2476. Biogenic SeNPs and TeNPs were also characterized and tested for their antimicrobial, antifouling and cytotoxic activities. Significant antimicrobial activity was shown for nanoparticles at relatively high concentrations (500 and 1000 µg/mL), with the antimicrobial activity of TeNPs being more significant than SeNPs. In contrast, against cell cultures (breast cancer cells (SkBr3) and human dermal fibroblasts (HDF) SeNPs showed greater toxicity than tellurium nanoparticles. Studies have demonstrated the high antifouling effectiveness of selenium and tellurium nanoparticles when introduced into self-polishing coatings. According to the results obtained, the use of SeNPs and TeNPs as antifouling additives can reduce the concentration of leachable biocides used in coatings, reducing the pressure on the environment.

Abstract
An infection caused by a rickettsia-like organism (RLO) was detected in the blue king crab Paralithodes platypus from the eastern Sea of Okhotsk. The external signs of the disease are lethargy and an empty gastrointestinal tract. Dissection of infected individuals revealed that their hepatopancreas was light yellow in color. The causative agent of infection is Gram-negative rod-shaped bacterium targeted exclusively at hepatopancreas tissues. In the cytoplasm of infected cells, the bacteria are enclosed in parasite vacuoles or located immediately in cytosol. An ultrastructural analysis showed two main morphological types corresponding to the life cycle stages in the RLO: the vegetative stage of intermediate bodies, characterized by growth and division processes, and the infection stage of elementary bodies, which are spore-like non-dividing short rods surrounded by a multilayered membrane and having an osmiophilic inclusion body. At the terminal stage of infection, as a result of lysis of the infected cells, the RLO enters the lumen of the hepatopancreatic tubules which contributes to the spread of infection. According to genetic analysis based on 16S rRNA gene sequences, the RLO from P. platypus is most closely related to the Candidatus Hepatobacter penaei, NCBI #JX981946 (94.7% similarity) and NCBI #KY363553 (94.1% similarity). The high level of genetic differences (more than 5%) of the studied pathogen, along with the structural features, allows characterizing the RLO isolated from P. platypus as a new species of the genus Candidatus Hepatobacter paralithodi nov. sp., NCBI #MK928971.

Abstract
Comparison of coding nucleotide sequences of the paralogous GH1 and GH2 genes, as well as of the growth hormone amino acid sequences, in the species of closely related salmonid genera Salvelinus, Oncorhynchus, and Salmo was performed. It was demonstrated that, in different groups of salmonids, the amino acid substitution rates were considerably different. In some cases, an obvious discrepancy between the divergence of growth hormone genes and phylogenetic schemes based on other methods and approaches was revealed. These findings suggest that the reason may be multidirectional selection at duplicated genes at different stages of evolution.

Abstract
The population genetic structure of Pacific smelt Osmerus mordax dentex from 25 locations in the Sea of Japan, Okhotsk Sea, Bering Sea, Kara Sea, Barents Sea, and White Sea was examined based on mitochondrial DNA variability. The genetic structuring of O. m. dentex over the larger part of the examined Eurasian range was weakly expressed, despite the high level of haplotype diversity (0.770 +/- 0.154). Hierarchical analysis of molecular variance (AMOVA) showed that the majority of molecular diversity (89%) was found within the populations. The most considerable differentiation of geographical populations for those grouped by their association with sea basins was observed for the Sea of Japan; with mean phi(ST) values of 0.114 (based on data from restriction fragment length polymorphism (RFLP) analysis) and 0.115 (based on sequencing data) (p < 0.01).
