Most while species should not be hunted, and not because some people think they are smart (i think they are as dumb as a sack of bricks) or cute. They reproduce extremely slowly and all it takes is for some politician to let the whalers take a excessive amount to get a few extra votes.
Here is a example. The Canadian east cost cod fishery (and more recently other less known species) was destroyed because the politicians didn't want to cut back the quota (how much fish can be harvested each year), leading to the collapse of the stocks and the sudden closer of the fishery that was required to save the species form extinction. To make matters worse... as soon as there is any sigh of recovery the fishermen demand the fishery be reopen in some shape or forum.. and it is thus preventing any recovery. The science was there the entire time telling the politicians just what was going on, but they chose not to listen and the government employees who conduct the research are bound by law to not disclose such information to the public.
The point i'm trying to make is that whatever number they come up with to justify the hunting of whales could very easily be simply made up, even if there is real science being done. Fish can recover from this given time, or just survive, whales won't.
The only product i know of that would justify this hunt would be the oil from certain types of whales that is actually better then any artificial lubricant on the market, as for food, there is enough non endangered/threatened species to eat out there.
Going off topic onto the seal hunt, you animal rights activist REALLY got your pryorities screwed up. Decades ago yes, seals where killed in inhumane ways sometimes, whatever was faster or cheaper, and a few guys had a sick sense of humor. Once upon a time this anti sealing campaign did have a realistic goal, a humane seal hunt. That has happened, no one who is right in the head likes the idea of a seal being skinned alive and so with the pressure and publicity no one dares to do such a thing anymore. You even managed to put a stop to the killing of white coats (juvenile seals who's fur is white, blends in with ice), even though there is no reason for this beyond they are cute to some people. The videos that these activist show around screeming bloodly murder are old videos, and some if not most of the more gruesome ones the activists ASKED someone to do what was shown. The population is at a healthy leavel, the quota has even been cut back this year due to increased juvenile mortality with poor ice condition (they breed on pack ice in the ocean) despite the uproar from the sealers as any such group(fisherman, lumberman, ect) will do when they will make less money.
Even though few here would believe me on this, i think this is partly a scam. With all these donations, all the volunteer work, some people are getting some pretty fat pockets, and if this issue went away those pockets would be a lot smaller. They prey on the stupid saying these poor poor cute creatures are endangered and skinned alive just for a few body parts and ask for a donation.
Come on, there is a commercial whale hunt based probably on bad (if any) science and you are worried a few cute oversize watter rats are being killed.
