Eight polymorphic loci were surveyed in three samples of the gastropodTegula rustica collected in a clean area of Peter the Great Bay and in three samples from a heavily polluted area of the bay. Macrospatial, microspatial, and temporal differences in allele frequencies and heterozygosity were found at some of the loci; however, the genetic similar...

This review summarizes information published in the 1980s–1990s about anthropogenic pollution in Peter the Great Bay, the largest of the bays in the northwestern part of the Sea of Japan. The coastal zone of the bay occupies about 12% of the area of Primorskii Province and is the most heavily populated. The bulk of the human settlements, the seapor...

Feeding habits of the Alaska greenlingHexagrammos octogrammus were studied in the coastal waters of Amurskii Bay in April–October 1997–1998. The greenling is characterized by a wide feeding spectrum of no less then 56 fish and invertebrate species. Decapods predominate in the diets of all fish age groups. The feeding spectrum ofH. octogrammus broad...

This paper presents data on 48 individuals of the rare high-boreal crab speciesGeryon tridens Krøyer, 1837, retrieved from the stomachs of cod caught in the southwestern part of the Barents Sea and adjacent waters in 1987–1997. There was only one large male with a carapace width of 58 mm; the other individuals were juveniles with carapace widths of...

In this paper, we analyze scale samples of sexually mature sockeye salmon from Lake Azabach'e collected over many years and data on the abundance of zooplankton in this lake. For native juvenile sockeye salmon, the major limiting factor of growth and smoltification is food availability. During the observation period from 1977 to 1993, two-year-olds...

The species composition and population densities of foraminifera were studied in scallop farming grounds in Alekseev Bight (Amurskii Bay, Sea of Japan). Ninety-one species of foraminifera were identified; members of the Elphidiidae, Discorbidae, and Ataxophragmiidae were numerically dominant. When the scallop mariculture farm was in operation, the ...

Linear growth rates and age-related changes in shell form are analyzed in the bivalveScapharca broughtoni from several areas of Peter the Great Bay, Sea of Japan. Mollusks grow fast during the first 4 to 5 years of life; at the age of 10–12 years, the annual growth increment in shell size does not usually exceed 1–3 mm. Irrespective of habitat, the...

The changes in distribution and abundance of the barnacleBalanus rostranus that occurred at various sites of Amurskii Bay in 1982–1995 were studied. Increased water and sediment pollution by industrial and sewage discharge were found to most significantly affect the abundance of larvae, food composition, and the availability of substrata suitable f...

We performed a short-term in vitro cultivation of interna fragments of the rhizocephalan barnacleSacculina polygenea, a parasite of the shore crabHemigrapsus sanguineus, and a histological study of an interna isolated from the host organism. It is shown that the colonial interna ofS. polygenea includes an extensive trophic system (a “root” system),...

This paper presents the results of the analysis of density dynamics of the larvae of the Pacific mussel in plankton, and experimental data on their settling on collectors in Vostok Bay, Sea of Japan, obtained in May–September 1989. It was found that, in the summer-autumn season, complex demographic processes occur on the suspended anthropogenic sub...
