"Seal culling in Namibia is a contentious issue, with animal rights groups opposing the practice as brutal, but the government supporting it and claiming the seal population may damage the fishing industry which is strategic to the Namibian economy. Seal harvesting in Namibia targets 86,000 seal pups and 6,000 adult bulls. This seal harvest takes place in three places namely, Cape Cross, Wolf Bay and Atlas Bay. "

"As I understand it, seal hunting is still allowed in Norway, Finland, Iceland, Greenland, and Canada (apologies if I’m missing a country here). I’ve seen a few threads on AH about seal hunting, but I hadn’t found much information regarding what opportunities exist internationally for nonresidents of these countries (i.e. US citizens). "
