Norway conducts commercial whale hunt as they didn't agree to the ban on whaling and ended up excluded from the ban. Japan conducts whaling under the guise of it being scientific (the meat gets sold). Iceland recently started commercial whaling and several groups of people (most live in the Arctic Circle area) subsistance hunt whales. I personally find only the latter acceptable. Japan may give up the scientific hunt for hunting rights around their coastline which may be sorted at the next IWC meeting.
It is mainly minke whales that are hunted but fin whales and a few other species are also taken.
