It depends on your area, but if you have rivers, creeks and lakes around, yeah, fishing is a good source. Be warned, even experienced anglers will spend hours fishing and catch little depending on all the factors. You have two types of fishing…active and passive. Of course active fishing can be time consuming, but doesn’t require as many calories as other food collection methods. Passive fishing, such as trot lines, using Yo-Yo reels or Speed Hooks are excellent…just like animal traps, and they allow you to set multiple hooks for increasing your odds and still allow you to multitask to do other chores. A combination of the two is a good strategy, but just like traps, fishing requires time, so it will slow you down if you have a short suspense on your travel arrangements.
A compact fishing kit is easy to assemble and with a couple of additions will make a good repair kit as well. I’ve built a couple in small containers that include sewing needles and even a mini razor blade. Fish line (my preference is Spyderwire or similar line) is great for clothing and gear repairs as well.
As to lures, I like dry flies, small spinners, plenty of hooks and even treble hooks. Those small plastic worms and lures don’t do well in the mini kits and they often get sticky and break down. As you plan your bug out bag, consider a small container to collect insects. As I hike or do any bushwhacking, I often run into several crickets, grasshoppers, etc. but when I’m ready to fish it seems like I can never find enough. I cut my grass on Saturday morning and collected over 30 grasshoppers and crickets; these netted me almost a dozen small brim…thinking ahead is a tough skill for me, but it’s panned out well! I know big lures will catch big fish, but depending on your skill and area, you’ll have to make that call. For compact kits, I am much more successful on smaller fish (brim, trout, etc.) than larger bass or catfish (not a lot of experience with catfish).
Casting can be a challenge and there are some soda can’s used which work well. I don’t care for them as they aren’t too robust in the pack. I’ve considered the smaller, narrower and stouter Red Bull cans, but anything similar will work. Those plastic Tube Vault containers work well and you can store dry flies, lures and extra line on sewing bobbins inside. I’ve seen some excellent PVC pipe projects that do the same thing…not a bad idea.
I love the compact Emmrod fishing poles and own a few. They are very robust, functional and compact. It takes a little use to working with a shorter pole, but for tight areas, they are the bee’s knees and they still can get some great distance when casting in open areas.
I’m pretty much setup for trout and panfish, but with a little more preparation, I can do some bass fishing for more meat…
Here's my Emmrod fly rod and a little brown trout I caught for breakfast...wish I would have landed the other two hits I had!
I keep some Speedhooks and a couple of Yo-Yo reels with my compact trapping/snare kit which also includes a little frog gig:
