Catching Fishes with Fire



One of the interesting ways to do fishing is to make use of fire. Fish farmers would simply wait for dawn or night to come and light a floating fire on top of the water. Eventually the fire attracts fishes and the fish farmers take this as an opportunity to trap them. This leaves us the question, why are the fishes attracted to fire?

Technically, it is not the fire that attracts the fishes but rather the light that it emits. Most fishes eats plants that are found under water. During daylight, plants absorbs light in what we call the photosynthesis process. These plants emits glowing light during night time. Fishes by evolution are sensitive to color underwater because of their eye receptacles. They can easily detect light so wherever their is light then their is food.
