Abstract
Habitation conditions significantly affect the physiological and biochemical state of aquatic organisms, including the balance of lipids that performs important functions in cellular metabolism. The lipid and fatty acid profiles of White Sea herring in Dvina, Kandalaksha, and Onega bays, and in the waters of Tersky Shore (the mouth of the Varzuga River) in autumn (after the fattening period) were studied. Different methods—thin-layer, high-performance liquid and gas chromatography—were used for this purpose. Determined heterogeneity on studied parameters of lipid metabolism of fish from different habitats is associated with differences in trophic and hydrological conditions in these bays. Variations of lipid compositions of herring groups can be a reflection of qualitative and quantitative strategies of biochemical adaptations, aimed at compensating the lipid metabolism of fish under different trophic–ecological conditions of habitation in the White Sea.
Highlights
The White Sea herring population, Clupea pallasi marisalbi Berg (Clupeiformes, Clupeidae), is one of the most similar forms to the Pacific herring, Clupea pallasi, and it is one of the most important commercial fish of the White Sea
The most notable influence of habitat factor was defined in terms of CHOL—30.1% (p = 0.0000), Total lipids (TL)—19.5% (p = 0.0001), and TAG—12.6% (p = 0.0076) (Table 1)
Biochemical analysis revealed that herring caught in the Kandalaksha Bay differed from those of the Dvina and Onega bays and the water area of the Tersky shore by having a higher level of total lipids (41.7%; 34.5%; 34.5%; 31.8% and 34.7% of dry weight, respectively) (Table 1)
Summary
The White Sea herring population, Clupea pallasi marisalbi Berg (Clupeiformes, Clupeidae), is one of the most similar forms to the Pacific herring, Clupea pallasi, and it is one of the most important commercial fish of the White Sea. Local herring herds are confined to certain hydrological conditions in different bays of the sea [1]. It was thought that White Sea herring from different bays of the White Sea belonged to a single population, a “single biological entity” [2,3]. There are other points of view, proponents of which consider that the forms of White Sea herring from different habitats in the sea have different origins [4–6]. It is supposed that herring are a complex of genetically-isolated forms, related by origin [7]. The growth of herring stock has been caused by gradual recovery of White Sea eelgrass, the decline of which happened in 1960 [8,9]
