A recent discovery reveals an increase in the number of deceased grey whales along the western coast of Vancouver Island, with a total of seven recorded fatalities this year. Paul Cottrell, the marine mammal coordinator at the Department of Fisheries and Oceans (DFO), mentioned that two additional dead grey whales were reported by a hiker and a pilot over the weekend, prompting the need for further investigation.
In April, four grey whales were found dead on Vancouver Island within just a 10-day span, sparking concerns. Cottrell expressed sorrow at the poor physical condition of the whales, remarking that they appeared emaciated. Researchers attribute these deaths to a significant decrease in available prey in the whales’ Arctic feeding grounds, leading to starvation during their migration back north.
The total count of grey whale deaths in the Pacific Ocean this year has reached 36, as per official records. John Calambokidis, a research biologist at Cascadia Research Collective, expressed surprise at the alarming rate of deceased whales being discovered, emphasizing the common factor of malnutrition among the examined carcasses.
Calambokidis highlighted the unprecedented rate of discoveries, stating that the situation is causing growing concern about the future. He noted that in 2019, during an “unusual mortality event,” 216 grey whales were found dead, marking a previous peak in mortality rates.
Collaborative efforts are underway between DFO and partners in California, Oregon, and Washington state to address the escalating issue. Cottrell anticipates more whale carcasses to be found during their northward migration until June, emphasizing the importance of ongoing data collection to assess the severity of the situation.
The grey whale population, estimated at slightly below 13,000, has been on a decline. Anyone encountering distressed marine mammals is encouraged to report the sightings to the Department of Fisheries and Oceans for appropriate action.
