eating raw fish

I know this is not the right forum, but the paleo Diet Forum seems really inactive. Ethically- I do not have any major problems with the consumption of wild fish (not all species of wild fish are ethically ok, but many types). Soooooo- what are the health concerns with the consumption of raw fish? Does the paleo diet shorten lifespan compared to raw veganism? Anybody know about the differences in a persons' health (between raw omnivorism and raw veganism)? Tweet
