Summary
Modified trap openings were developed to reduce juvenile rockfish bycatch (Sebastes sp.) in British Columbia (Canada) spot prawn (Pandalus platyceros) traps. Smaller trap openings had no impact on rockfish or other non-target species bycatch. A novel bent tunnel opening resulted in no rockfish bycatch and the exclusion of other fish species. However, all trap modifications resulted in reductions in prawn catch rates. Large prawns were also excluded more than small prawns.
