“…Specimens of the Arctic gadoid, E. (navaga) nawaga were collected from the White Sea (64°35 0 N; Christiansen et al 1995). They were taken from beneath the ice on the bottom at a depth of &1 m in water at a temperature of &-1°C, SW osmolality of 585.0 ± 7.1 mOsm kg -1 (n = 4).…”

Concentrations of both inorganic and organic blood plasma/serum components of teleost fishes were reviewed in seven habitat/life-history categories. These were: freshwater; inland saline; estuarine and nearshore marine; pelagic and deepsea; diadromous; southern cold-water; and northern cold-water. Plasma/serum osmolalities were compared among groups acclimated to/living in fresh and in salt water. Contributions of inorganic ions and colligative and non-colligative organic molecules were evaluated including with respect to melting and freezing points, and ''antifreeze activity'' of plasma/serum in species from cold marine waters. Possible roles of TMAO in deep-water fishes were reviewed. Discussion also included influences of ambient salinity and temperature on concentrations of plasma/serum components. Seasonal cycles of blood plasma/serum components were discussed, along with antifreeze concentrations in other body fluids and tissues of cold-water fishes. Regulatory patterns of plasma/serum osmolalities were compared among the most euryhaline of teleosts evaluated here. Highest mean values of plasma/serum osmolalities in sea water were seen in southern cold-water and in pelagic and deep-sea fishes. The southern cold-water group also had the lowest plasma/serum freezing points among these groups. Comparisons of mean plasma/serum Na ? and Cl -concentrations among fishes from fresh waters did not differ significantly among groups, but species from cold marine waters showed higher levels than did other groups in marine waters. Plasma/serum osmotic, Na ? and Cl -concentrations of these seven groups of teleosts were compared with those of other fish-like vertebrate groups. Possible impacts of global warming on regulatory responses of plasma/serum components were discussed.

“…Research on the embryonic and larval development of Navaga under laboratory conditions were conducted by Doroshev and Aronovich (1974) and Aronovich et al (1975). Some features of the physiology of the species are described in the papers of Schurmann and Christiansen (1994), Christiansen et al (1995), and Hassinen et al (2014). An assessment on the accumulation of heavy metals in Navaga was done by Christiansen and Bjørnstad (1996).…”

Navaga, Eleginus nawaga, are an important component of some Arctic shelf seas, primarily in the Russian Arctic, yet very few publications on Navaga are available in the western scientific literature. Based on literary sources, a description of the distribution and biology of Navaga, Eleginus nawaga, in the White Sea, as well as a history of their fishery, are provided. Long-term changes in biological parameters of several Navaga populations, as well as the current state of the Navaga stocks are summarized. In recent decades, the size and age structure of Navaga populations have undergone significant changes. In Onega and Dvina bays there was a significant rejuvenation of stocks; in contrast, an aging population was observed in Mezen Bay and the Voronka, which was due to climatic changes in all areas of the White Sea. Catches of Navaga have remained at a stable level for more than 100 years, which indicates a stable state of the stocks of this species. Future studies of Navaga in the White Sea should focus on such important aspects as migration, spatial and vertical distribution of juveniles and adults, population structure, biomass and population dynamics, fishing and natural mortality, as well as habitat conditions.
