A recent discovery of additional deceased grey whales along the western coast of Vancouver Island has brought the total count to seven this year. Marine mammal co-ordinator Paul Cottrell from the Department of Fisheries and Oceans (DFO) mentioned that two dead grey whales were reported over the weekend by a hiker and a pilot, prompting the need for further investigation into the cause of death.
In April, four grey whales were found dead within a span of 10 days on Vancouver Island, initiating a troubling pattern. These whales were described as emaciated, with Cottrell expressing sorrow over their condition. Researchers attribute the rising death toll to a significant reduction in available prey in the whales’ Arctic feeding areas, leading to starvation as they migrate back north.
The escalating number of grey whale casualties, totaling 36 in the Pacific Ocean this year according to official records, has raised concerns. John Calambokidis, a research biologist at Cascadia Research Collective, expressed his growing alarm over the situation, noting that malnutrition has been a common factor among the examined deceased whales.
Calambokidis highlighted that the pace and volume of deaths this year have surpassed previous records, causing heightened worry within the scientific community. Collaborative efforts are underway between DFO and partners in California, Oregon, and Washington state to address the situation and prevent further population decline.
As the investigation continues, Cottrell anticipates more deceased whales to be discovered during their migration period until June. With the grey whale population estimated at just under 13,000 and facing ongoing threats, reporting any distressed marine mammals to DFO is crucial for conservation efforts.
