Target catch: 

giant mud crabs (Scylla serrata), blue swimmer crabs (Portunus armatus)

Effect on bycatch species: 

91-mm traps retained significantly fewer (by 42%) undersized P. armatus and A. australis. In the second experiment, fewer undersized S. serrata, P. armatus, and A. australis were retained in all larger meshed traps, and in all traps with escape gaps.
