what I saw on the government's website it said that they raised the quote to 400,000 for the 2014 hunt. The link is in the paragraph below.
Based on this government website it looks like they are being purposefully vague when it comes to the fur trade, and it even states that the government is committed to developing new markets. One company can't be the only producer of all of those products the seal pelt can create.
Sealing in Canada - Frequently Asked Questions
Supplements are adequate enough as a replacement for meats when it comes to omega 3's, and there are other foods that are higher in omega 3s that do not come from animals. They should invest more in those more humane foods that do not require clubbing or licenses to kill in my opinion.
Seals are not the main reason fish are becoming more scarce, it's human interaction through over-fishing, and if there are studies showing otherwise then it's probably being funded and edited by the government that supports it or the industry that is involved in it. I view the Canadian government when it comes to the seal hunt in the same light that I view the Japanese government in the whale hunt. Both have stellar reputations when it comes to many things but have disgusting practices that they cling to for the sake of profit. These fisherman's livelihoods do not and should not depend on the slaughter of 350,000 seals, and the fact that they claim it does and that the government acknowledges that they do shows how it's not about conservation but about commercial profit in my opinion.
