摘要:Prawn trawling is a non-selective form of fishing however, prawn/scallop trawl nets are designed
and set so that they are generally more efficient at catching the target species than bycatch as in
most cases these species require significant sorting and handling and are discarded overboard.
Using demersal trawling as a sampling method has its limitations in describing the overall
biodiversity of a region because of what the nets sample effectively. This study should not be
considered as a project describing overall biodiversity in the areas sampled but the biodiversity
of fauna caught in prawn trawl nets. Limited sampling with fish trawl gear was undertaken at
a few sites on one occasion to determine selectivity characteristics of the prawn net compared
to a fish trawl net but these trials were not comprehensive.
