Want to raise fish high in omega-3 fatty acids

[bsfman]

You can try feeding purslane to your fish...it's high in omega 3 and vitamin c.

Thanks for this info! I've never tasted nor, far as I know, even seen purslane. Might just give it a try! Found some links to seed sources.

Have you any experience growing purslane, David? Would it work okay in a floating raft system?
