What problem can using lights at night cause when fishing in very turbid water?

They can sometimes be too effective, drawing in smaller, unwanted organisms or sediment close to the light cone, which then fouls the net.

When employing light attraction methods in murky or turbid waters, a specific counter-intuitive problem can arise. While lights generally attract the target shrimp species, the very effectiveness of the light cone in drawing organisms toward the source means it also attracts undesirable elements present in the water column. This often includes fine sediment, detritus, or non-target, smaller organisms. When the net is deployed into this illuminated zone, the collection of this extraneous material results in the net becoming fouled, complicating the harvesting process and potentially reducing the catch quality of the desired shrimp.
