15.3.Separator Trawl
Unit 15 - Selectivity in fishing gear
15.3.Separator Trawl
Several methods have been developed for the separation of fin fishes from shrimps and escapement of juveniles during trawling operation. The separator trawl has a dividing panel that extend far enough ahead and be constructed of a mesh size small enough to prevent fish in one side leaking into the other as may happen as the catch accumulates. It is further advantageous that the extension section is modified so that codend of normal length and circumference can be used, rather than dividing an extension section designed for the single codend and fitting into two half sized codend.
