Circumpolar genetic population structure of capelin Mallotus villosus
Capelin Mallotus villosus is the most abundant pelagic fish species in boreal and subarctic waters. The ecological and commercial importance of capelin emphasizes the need for a better understanding of the genetic population structure of the species and the mechanisms underlying its population dynamics. With this aim, 1155 capelin from the entire distributional range of the species were genotyp...
متن کاملSwimming energetics of the Barents Sea capelin (Mallotus villosus) during the spawning migration period
The Barents Sea capelin, a schooling species, undertakes extensive migrations against the predominating current north of Norway to its spawning grounds along the Norwegian and Russian coasts. Low swimming costs (i.e. high efficiency) at cruising speeds would be advantageous for capelin, enabling allocation of more energy to reproduction. A high oxygen uptake capacity may however also be benefic...
متن کاملGenetic Structure of Capelin (Mallotus villosus) in the Northwest Atlantic Ocean
Capelin (Mallotus villosus) is a commercially exploited, key forage-fish species found in the boreal waters of the North Pacific and North Atlantic Oceans. We examined the population structure of capelin throughout their range in the Canadian northwest Atlantic Ocean using genetic-based methods. Capelin collected at ten beach and five demersal spawning locations over the period 2002 through 200...
متن کاملArsenic-containing hydrocarbons: natural compounds in oil from the fish capelin, Mallotus villosus.
Arsenic-containing hydrocarbons have been identified for the first time as natural components of fish oil.
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
