Research on seaweeds provides a continual discovery of natural bioactive compounds. The review presents new information on studies of the potential and specific antiviral action of phlorotannin and their derivatives from marine brown algae. Phlorotannin is a polyphenolic derivative and a secondary metabolite from marine brown algae which exhibits a...

AbstractData on the spatial distribution of the Walleye Pollock, Theragra chalcogramma, and the conditions of the habitat off the southern Kuril Islands in the spawning season of 2015 and the feeding season of 2016 are provided in this report. In the spring, most walleye pollock are distributed more evenly over the shelf and continental slope to a ...

AbstractThe distribution and abundance of four common myctophid fish species in the upper epipelagic layer of the northeastern North Pacific in winter were analyzed based on results of the research surveys in the Gulf of Alaska in 2019 and 2020. The myctophid community in the considered layer was dominated in number by blue lanternfish, Tarletonbea...

AbstractThe phenomenon of population waves of nekton in the Kuroshio Current system is discussed using the example of the Japanese sardine Sardinops melanostictus, one of the most common species that show the greatest amplitude of abundance fluctuations. So-called “sardine epochs” are distinguished on the basis of the pattern of abundance fluctuati...

AbstractA decrease in the rate of growth in fish, which is one of the most important characteristics of stock dynamics, can result in a decrease in their abundance, as is widely accepted in classical fisheries ichthyology. A study of growth patterns in pink salmon year-classes with different survival rates during the marine period of their life his...

AbstractThe dynamics of demersal fish biomass is considered based on the results of trawl surveys conducted in 1977–2015. An analysis of the status of fish stocks has shown that fishing pressure did not have a significant impact on the dynamics of their biomass and abundance. This applies not only to the fluctuating species (walleye pollock, arabes...

Abstract—The dynamics of sablefish stocks and fishery in the Bering Sea, the Gulf of Alaska, and off the Aleutian Islands are considered based on the data of bottom and midwater trawl surveys conducted by TINRO in 2003–2020, fishing statistics, and open-access data of the National Oceanic and Atmospheric Administration, United States. The sharp inc...

AbstractMore than 50 species are known in the genus Pseudo-nitzschia H. Peragallo, 1900. Seven of them were recorded in the Black Sea. Due to the high morphological similarity, many representatives of the genus are considered to be cryptic; their reliable identification requires the use of different, often very resource-consuming methods. The aim o...
