Summer mesozooplankton community of Moller Bay (Novaya Zemlya Archipelago, Barents Sea)
No full textNovaya Zemlya Archipelago is the eastern boundary of the Barents Sea. Theplankton of this region have been less intensively studied than thoseof other Arctic areas. This study of the mesozooplankton assemblage of Moller Bay was conducted in August2010. The total mesozooplankton abundance and biomass ranged from 962to 2980 individuals m-3 (mean ± SD: 2263 ± 921 indiv.m-3) and from 12.3 to 456.6 mg dry mass m-3 (mean ± SD:192 ± 170 DM m-3) respectively. Copepods and appendicularians werethe most numerous groups with Oithona similis, Pseudocalanusspp.,Acartiaspp., Calanus glacialis and Oikopleura vanhoeffennibeing the most abundant and frequent. Mesozooplankton abundance tendedto decrease with depth, whereas an inverse pattern was observed for the totalbiomass. Total mesozooplankton biomass was negatively correlated with watertemperature and positively correlated with salinity and chlorophyll aconcentration. Comparison with previous data showed significant interannualvariations in the total zooplankton stock in this region that may be due todifferences in sampling seasons, climatic conditions and the distribution ofpotential food sources (phytoplankton and seabird colonies)

Get PDFThe Barents Sea is regarded as one of the world’s most unique regions with its high summer productivity. However, there were a few studies dealing with estimation of daily secondary production in the Barents Sea. The aim of the present study was to conduct an investigation of the pelagic mesozooplankton assemblage in the Barents Sea, to calculate daily production levels of mesozooplankton and to analyze the relationship between the community structure and environmental drivers.Structure of zooplankton communities was investigated within the main water masses of the Barents Sea in the summer 2013 (June–July). Calanus finmarchicus presented as copepodites IV–V dominated in terms of the total zooplankton abundance and biomass in Murmansk Coastal Water and Atlantic Water. Spring phase of zooplankton succession cycle was found in Arctic Water where Copepoda nauplii were the most abundant and Calanus glacialis dominated by zooplankton biomass. Zooplankton of the Barents Sea Water had features of spring and summer phases of zooplankton succession cycle. Spatial variations in the zooplankton distribution were associated with hydrological conditions and phytoplankton density. Maximum of the mean zooplankton biomass was registered in Atlantic Water (30,7 mg dry mass/m3) while the minimum was found in Barents Sea Water (5,4 mg dry mass/m3). Calculated daily production of zooplankton ranged from 0,01 to 1,57 mg dry mass/m3 per day. Total zooplankton stock for the study area of 281 000 km2 was estimated to be > 740 000 t of dry mass. The obtained values of zooplankton biomass and stock were considerably lower than in previous years, which are probably connected with higher predator pressure — grazing of zooplankton by capelin and other predators as well as with possible climatic influence.Исследована структура зоопланктона в пределах основных водных масс Баренцева моря. В мурманской прибрежной и атлантической водной массах по численности и биомассе зоопланктона доминировал Calanus finmarchicus. В арктической водной массе преобладали науплии копепод, основу биомассы составлял Calanus glacialis. Пространственные вариации распределения зоопланктона были связаны с гидрологическими факторами и концентрацией фитопланктона. Наибольшая средняя биомасса отмечена в атлантических водах, наименьшая — в баренцевоморских. Общий запас зоопланктона для исследованной акватории площадью 281 тыс. км2 составил более 740 тыс. т сухой массы. Биомасса, продукция и запас зоопланктона были существенно ниже, чем в предшествующие годы, что, скорее всего, связано с более высоким прессом мойвы и других хищников, также возможным влиянием климатических факторов
Amino Acid Composition in Different Tissues of Iceland Scallop from the Barents Sea
No full textThe Iceland scallop from the Barents Sea is a commercially important species with promising aquaculture potential, but information on the biochemical properties of its tissues is limited. Our analysis of the adductor muscle, gonad, and mantle of this bivalve mollusk from coastal waters provided insight into its amino acid composition. Biochemical analysis revealed predominant levels of glycine (11.8, 11.5, and 9.6 mg g−1, respectively) and arginine (11.2, 8.3, and 5.8 mg g−1, respectively). While multivariate comparisons did not reveal significant differences in amino acid composition between the tissues, single comparisons showed significantly higher levels of arginine and leucine in the adductor muscle compared to those of the mantle. The abundant presence of glycine and arginine underscores their importance in maintaining basic physiological processes, consistent with other scallop species. Redundancy analysis identified water depth and scallop gonad index as influential factors shaping the amino acid profile in the adductor muscle. In the case of the mantle, water temperature emerged as the main driver of amino acid content. Our results confirm the richness of essential amino acids in scallop by-products and highlight their potential for human consumption, production of feed ingredients for farmed animals, and nutraceuticals
