A month ago, a worldwide gathering of Marine scholars and biologists presented a report to the International Whaling Commission, Slovenia, highlighting a disturbing hike in the number of whales washing shorewards to India’s west coast over the most recent two years. The report referred to 16 occurrences of whale mortality along the west drift in 2015, trailed by 20 in 2016. This was colossally more than in any year in the vicinity of 2001 and 2014 when the number of whales passings never surpassed four.
From the withered look of the corpses washed aground in the past 2 years, scientists concluded that they were short of sustenance and food, and drew nearer to the shores searching for fish. They say the fish populace in the ocean has lessened definitely because of a sharp reduction in dissolved oxygen in the water. The group that composed the report included three individuals from the Konkan Cetacean Research Team (KCRT) other than specialists of James Cook University in Australia, the Terra Marine Research Institute in Bangalore and the Department of Oceanography of the University of Washington in Seattle.
Days after the group presented the answer to the universal commission on May 9, two parts of the deteriorated body of a 44-foot Bryde’s whale washed aground at two distinctive shorelines of Mumbai on May 20. Maharashtra has revealed the most elevated number of whales since 2001 — 37, a few times more than Gujarat (11), Karnataka (11) and Kerala (9). These incorporate 23 remains washed shorewards.
Vinay Deshmukh, sea life researcher and previous boss researcher of Central Marine Fisheries Research Institute (CMFRI), clarified the conceivable reason, saying: “The Indian Ocean and the Arabian Sea have a great amount of dissolved oxygen for fish to breath. In any case, that has started to diminish and there are presently oxygen least zones in the Arabian Sea with low levels of dissolved oxygen. The fish populace has dropped conceivably because of this, and this has likewise presumably attracted the whales nearer to the shores.”
The report, as well, harped on the adjustment in the fish populace. It was additionally expressed by CMFRI (Central Marine Fisheries Research Institute) that there was a peak in jellyfish amid the time. Such shift in prey-predator populaces is most likely causing a cascading effect in the marine life and food chain.
