VANCOUVER -- The impacts of climate change could soon force some ocean predators in the Arctic to feed on what researchers are calling "marine junk food," a new study out of B.C. suggests., found distribution of some fish species will speed up by 2025. Those changes will likely impact Artic predators, like ringed seals.
"It costs energy to forage. Does that mean the seals will need to spend more energy to get a larger number of these smaller fish for the same amount of energy as capturing a bigger fish?" Florko said. Complicating the situation, there could be some potential benefits to these changes. For beluga whales, capelin are a staple in their summer diet so their increase could be positive. However, the whales rely on eating Arctic cod to store body fat.
