If you want to make a small survival pack for fishing
Many survival packs
today got a small set of fishing hooks, line and sinkers. Usually the hooks are very small because of the size limits so it does not take so much space in the set with all the other items.
I do recommend
using some hooks with some size like on the picture because it will increase the chances of getting larger fish and for other reasons. On the picture are some different types that could be placed in a set. I also recommend putting some strong multifilament
line in the set because this will increase the chances of landing a good size fish.
There are differences from inland and sea fishing but usually they will works anywhere.
There are hundreds of different things you can put on a hook to increase the chances. You can use plastics, threads or rope + much more. For a sinker you can use a piece of metal. You can also make a hook from
a nail, wood or metals. Plastic from an electrical cable can be stripped and used on the hook. Red is maybe the best color on the sea. You would be surprised with just a plain hook or a normal black hook without any more on it. Many fishes will bite
on just a plain hook. If you get the chance to get some bait from insects, snails, fish, meat or worms then the chances increases by 100%.
