Sammendrag
Gillnets are one of the most commonly used fishing gears in both marine and inland waters. Different colour
filament nettings are often used in gillnets. However, the effect of gillnet colour on catch efficiency is unclear for
most fisheries. Therefore, in this study we investigated the effect of gillnet colour on the catch efficiency in
pearlspot (Etroplus suratensis) fishery in Vembanad lake, India. Gillnet colours tested were transparent, green and
blue. Results showed that in this fishery, the catch efficiency of gillnets of the three colours tested differed
significantly. The highest catch efficiency of pearlspot was shown by green gillnets compared to transparent or
blue netting. Specifically, green gillnets on average were estimated to be 74% more efficient compared to
transparent gillnets. For the green compared to the blue gillnets, the catch efficiency was estimated to be higher
by 81%. These results demonstrate that gillnet colour can be an important factor significantly affecting the catch
efficiency of this fishing gear.
