Codends modified with rectangular mesh panels (one oriented length-wise in the cod end and one oriented width-wise, each measuring 7 x 11 bars) reduced the weight of discarded bycatch by 46% and 38% respectively but did not significantly reduce the catch of targeted prawns. A haulback delay of 10-15 seconds allowed juvenile red spot to escape through the square mesh panels, while trawls with no delay showed no significant reduction in the bycatch of this species.
