In addition, beluga whales have undergone semen collection, [249] body temperature data collection, [251] reproductive tract examinations via transabdominal ultrasound, and endoscopic exams. [254] With new technology, the reproductive characteristics of both the female and male beluga whale have been accurately described and has benefited ...
As part of 1980s hunting regulations, quotas were set for Inuit harvests: the annual quota for belugas hunted in Cumberland Sound was 35 whales between 1992 and 2001, and was increased to 41 whales in 2002. Total landings between 1992 and 2001 fluctuated between 15 and 50, averaging 36 to 37 belugas per year. [1]

A 2010 study considered whales to be a positive influence to the productivity of ocean fisheries, in what has been termed a "whale pump." Whales carry nutrients such as nitrogen from the depths back to the surface. This functions as an upward biological pump, reversing an earlier presumption that whales accelerate the loss of nutrients to the ...
