In the 1980s–1990s, takings of harp seals totaled 8,000–10,000, and annual catches of hooded seals totaled a few thousand between 1997 and 2001. [1] Norway accounts for all recent seal hunting in the West Ice, as Russia has not hunted hooded seals since 1995, and catches harp seals at the East Ice in the White Sea – Barents Sea. [4]

[112] Male ringed, crabeater, spotted and hooded seals follow and defend nearby females and mate with them when they reach estrus. These may be lone females or small groups.
Seal muscle has a very high myoglobin concentration, which varies in different muscles and hooded seals have the capacity to store about six times as much oxygen as humans. Myoglobin has a considerably higher affinity for oxygen than haemoglobin, so if the muscles are perfused during a dive, the oxygen on the myoglobin will only become ...
Harp seal blubber contained 9.2% while the muscle tissue contained only 3%. High levels of trace elements were found. In particular, hooded seal muscle meat contained 379 μg/g of iron and harp seal muscle meat contained 30 μg/g of zinc. [5] High levels of mercury have been found in the blubber of seals of the Canadian arctic. [6]
