Light in kelong fishing technology

Research basis

A study in Lingga compared submerged lights and pressure lanterns under particular conditions. Its reported observations inspire scientific questions, but do not establish one universally superior fishing light.

Variables to consider

Light colour and intensity, depth, turbidity, timing, moon phase, species, fishing effort and non-target organisms can all affect observations.

Animal-free classroom experiment

Measure torchlight transmission through clear and slightly turbid water containers. Avoid intense light to eyes and disturbance of wildlife.
