Oxfam's ad was a bit fishy

The advert that Oxfam dreamed up to celebrate International Women's Day was a bit illogical and rubbish. It claimed that if you taught a man to fish, he'd be able to feed himself for a lifetime (in reference of course to the aid mantra about fish and fishing rods). But if you taught a woman to fish (it claimed), then she'd start a business and sort out the whole village. Am I to assume that no women at all have actually been taught to fish yet? No doubt the bicycle fits in there somewhere too. But where?
