Fishing whales

I don't know what to say when I look at this pictures.Is another kind of fishing, something new for me.I didn't saw something like this before.I think that this is really crazy and amazing, but it this legal ? Commercial hunting of whales has been outlawed since 1986, because many of the great whale species are endangered. Iceland, which stopped whaling then under international pressure, now says it must control whales to protect fish stocks and fishermen's livelihood.
