Technique for catching shrimp with nets at night 

At night there is an opportunity to earn a living from Lake Anak Laut Jhon, which is behind the local residential area. The sustenance sought is shrimp. Shrimp can only be caught in the dark of night when the water of Lake Anak Laut is receding.
Apart from low tide, another condition for attacking shrimp is that the water must be clear. If the shrimp are cloudy, you can't see them. To catch them, a flashlight is aimed at the surface of the water to see the shrimp. Thanks to the flashlight, the shrimp can be seen clearly, especially their red eyes.
