El Nino is forecasted to attract more sharks due to a shift in temperature in New Zealand’s coastal waters. This change is expected to increase fish life, which in turn will draw more sharks. This warning comes after a teenager was killed by a shark off South Australia’s coast, marking the third fatal attack in the region this year. Shark attacks have also been reported in New Zealand waters.
Marine scientist Riley Elliott explains that El Nino differs from La Nina climate patterns in terms of wind direction across the Pacific Ocean. El Nino results in a drop in water temperature by about 5 degrees and creates conditions favorable for increased fish life.
Despite the expected increase in shark numbers, Elliott assures that more sharks do not necessarily mean more shark attacks. He advises people to be aware that sharks are predators and to take precautions to reduce risk. For instance, people should avoid throwing fish carcasses overboard when fishing and leave the area if they see sharks. Swimmers are also advised not to swim where people are fishing.
Elliott emphasizes that the risk of drowning is significantly higher than shark attacks. He encourages anyone who sees a great white shark to report it to the Department of Conservation. The department also welcomes reports of shark sightings, captures, or strandings.
