The development of the diatomChaetoceros salsugineus from Amurskii Bay in the Sea of Japan was investigated in laboratory culture. It is shown that the intraspecific taxaC. salsugineus f.salsugineus, C. salsugineus f.curtus, andC. salsugineus f.solitarius correspond to particular stages in the development of this species in culture. Problems of the...

This paper deals with the ecology, settlement age structure, and shell variability of the gastropodCeratostoma burnetti (Adams et Reeve) (Muricidae) from Pos’eta Bay (Sea of Japan). A change in the shell structure occurs between the open and inner bights of the bay: the shell sculpture smoothes, the ratio of body whorl diameter to height grows, the...

The effect of decreased salinity on the limpetsCollisella dorsuosa, C. versicolor, C. radiata, andNotoacmea concinna (Mollusca, Gastropoda) is studied at early stages of development. It is shown that, for normal development from fertilization to the veliger stage, the salinity must be not less than 22–24‰. A decrease in salinity depressed the behav...

This paper discusses the history of hydrobiological investigations in the Far-Eastern seas performed by three centers, the Leningrad center, the Moscow center, and the Far-Eastern center during the period following the Second World War (from 1946 to the present). It is shown that most of the scientific expeditions in the Far-Eastern seas took place...

The taxonomic composition and annual dynamics of abundance of pelagic larvae of bottom invertebrates in Avachinskii Inlet (southeastern Kamchatka) were studied. Larvae of 52 taxa were identified. Larvae were found in the plankton all year round. The highest concentration of meroplankton was recorded in the spring and fall. During the year, meroplan...

Macrobenthos communities were studied on fringing reefs of the An Thoi Islands using scuba-diving techniques. The islands are located in the turbid and highly eutrophic waters of the eastern Gulf of Siam. We studied species composition and population densities and biomasses in common species of algae, coelenterates, mollusks, and echinoderms and al...

The fatty acid and lipid composition of different parts of the thallus of the brown algaSargassum miyabei was studied. The upper and lower thallus regions markedly differed in amounts ofn-3 polyunsaturated fatty acids (PUFAs), monoenoic fatty acids, phospholipids, and glycolipids. The lower thallus regions were rich in monoenoic fatty acids and pho...
