Ivey...... when I move to Eastern Connecticut, I started keeping track of conditions with a log just like yours to document what was working/not working in unfamiliar lakes,ponds,rivers. After a couple of years I found that was no longer needed, I had learned to pay close attention and remember important details. Learned lots about barometric changes during this time. I strongly recommend using a log to all, including experienced anglers. Does not need to interrupt fishing, I often completed my entries in my car immediately following fishing.

Not that I'm aware of. But the Department of Fish and Wildlife ( California version ) puts out information on which fish are safe and which ones should be avoided or at least limit the intake of. I'm sure most states do that, and you can go online and check that out. As far as providing yourself with sustenance over a long period of time, like you're talking about, I would certainly speak with someone who knows a thing or two about nutrition and the intake of heavy metals - that's what you need to worry about, lead, mercury, things like that.
The piers around where you live will be a good place to start out learning the basics of fishing. You don't even need a license in California to fish piers. Head to a pier and watch how other folks do it. Don't be afraid to ask questions - fisher people are generally pretty friendly and willing to share information. Go on the internet to YouTube, there are tons of videos that will teach you the basics. And this site is a wealth of information. Don't hesitate to ask us questions, we're happy to help. We all started out knowing nothing, so don't be shy.
Once you're comfortable fishing the piers we can talk about some of the fresh water lakes you might be heading to to camp. We can help with that too. Just let us know what you're interested in. And you can pm me anytime, I'll be glad to help you out.
