Junka Matsuda (Hokkaido University Graduate School of Fisheries Science and Sciences Academic Researcher), which specializes in whales, explains the status of whales and dolphins in Hokkaido in an easy -to -understand manner while showing photos and illustrations.did.Dolphin and whales stranding surveys are to investigate the individuals that have been raised for some reason as an academic specimen.In Hokkaido, there are about 60 whales and dolphins a year.If you examine the contents of the dolphin and whales in detail, you will see the part of the squid or octopus chin, the otoliths of the fish and the chin of the chin.You can tell what you are eating from such a stomach content.However, garbage may come out instead of food from the stomach of some individuals.In addition to plastic bags and hooks, you can also find invisible plastic called microplastics in the stomach.It is said that about 8 million tons of plastic is now leaked into the ocean.In addition to drifting and drifting garbage, garbage also exists on the seabed.It is necessary to avoid new leaks and reduce the amount of garbage that exists as much as possible.The photos of plastic garbage, which were actually found in the dolphin and whale's stomach, were very shocking.He wanted to continue his research on what such garbage was incorporated into the body.In this lecture, I received the impression that "I learned very easy to understand."It was an opportunity to deepen our knowledge of dolphin and whales and knowledge of stranding surveys, and to increase interest in marine environment.
