Hmm, the only good seed/nut I have ever heard of was walnuts(they have a good omega-3/omega-6 ratio, apparently, unlike most other nuts) -oh, and raw pumpkin seeds are an excellent source of magnesium if one is consuming overly-calcium-rich raw dairy). My advice would be to buy those cheap enclosed plastic dishes one can find in most big health-stores and grow some sprouts instead. Sprouted seeds have no enzyme-blockers and are far higher in nutrients.
Some seafood is far more likely to be wildcaught than others. I am not as up-to-date re info as before, as I mostly only eat raw wild game these days. However, I believe that salmon and prawns/shrimps are almost always farmed(oysters, tuna and mussels sometimes are farmed). Fish like sprats, sardines, mackerel, swordfish, kingfish and sharks aren't farmed yet, afaik. You'll have to do more research on this. Also, a great idea would be to visit local markets and talk to the people there. In the UK, I would mostly only buy from a fishmonger who fished most of the week but then sold his fish in farmer's markets on 2 days of the week. His catch was, of course, 100% wildcaught as he didn't have the cash to set up any fish-farming. Of course, you'd need to speak Chinese/Hokkien to get the best results.
You can't do that now, perhaps, but you might, in future, create Lex's beef jerky-maker(as found on rawpaleodiet.com) and then just make a dozen kilos of beef jerky beforehand.
