To carry or not to carry?
That is the question.........

Ok, contrary to received wisdom a small fishing should be carried.

It should contain:
2 rubber jigs.
2 wire leaders.
As many clips etc as you like.
40' backing line (of the sort used by fly fishermen.
40' 10-12lb line.
20-25 barbed hooks. Small and medium sized. For ease of handling put the hooks on safety pins.
2 large gaff hooks.
10-20 snelled hooks.
split shot.
Nylon cordage.

Use the rubber jigs and the backing line to hobo fish.

The gaff hooks are for hooking frogs and other small critters as opportunities present themselves.

The snelled hooks are for trot lines and the like.

The extra hooks and line are for anything else. Get creative and educate yourself in every poachers trick going. The more illegal and unsporting the technique, the more effective it is likely to be.

The matches are a good idea as is a couple of single edged razor blades.

If this is an emergency then constructing a spear might be a worthwhile exercise as are throwing sticks and the like.

As a general rule: you are more likely to find a feed near and on a lake than anywhere else except possibly a sea shore.
