hmmm, well I live on the Atlantic Ocean, so what I take differs greatly from the guy up in the mountains fishing for trout.
I do, however, try to keep my kit as versatile as possible, and what I think will do best over a variety of ecosystems.
I have no idea exact numbers of the following items, but I give you an outline of the stuff.
bobbers, different hooks, line, sinkers, artificial bait and that is about it I think.
I try to keep it as simple as possible, this all fits together in a tin about one inch deep, three inches wide, and five inches long.
Sorry, just reread your post about bait and tackle.
You have to realize that there are a lot larger fish, sharks and such, so all of the tackle and bait are heavier duty and bigger to compensate for the size difference.
We have smaller bait fish, such as shrimp, fiddler crabs, minnows, mullet, and many others.
So, I try to include basic materials to fashion a net together, as well, because
fish prefer live bait and i could eat the bait if need be.
In the ideal world, I would be able to bring a cast net, a surf-fishing rod/deep-sea rod, but all this would be to bulky and heavy to go in BOB.
So, I include line fifteen pound test wrapped around an old gift card, and I can make a rod if I need to.
Hope this helps, you just got to remember to include the necessities and make the basics when you have to, weight is an issue and the lighter the better.
