Hooks are used for fishing but on a small scale. The size of the hook used depends on the type of fish. Hooks have numbers. The lower the number, the bigger the hook. Hooks used for tilapia are from numbers eleven to sixteen. Those for nile perch are from seven to 10. Lung fish are fished with hooks of numbers six and five. Bigger hooks are used for bigger fish so that they do not break free and swim away.
