Most of the remainder of the catch is taken as bycatch of snapper bottom trawl tows. Bottom pair trawling also accounts for a considerable proportion of TRE 7 landings and appears to operate similarly to bottom trawl. The possible duplication of effort reporting for pair trawling makes it a dubious candidate as a method from which a CPUE index might be derived. A small set net fishery also mainly targets trevally in similar statistical areas and months to the bottom trawl fishery. Its catch has declined in recent years and it was not considered for CPUE analysis.
