To quantify and map the benthic invertebrate species incidental catch in commercial and research trawling throughout the New Zealand EEZ 1. Collate and review the international literature on methods of reducing bycatch in crustacean trawl fisheries. 2. Review and analyse the data from New Zealand studies. 3. Develop recommendations on future approaches to reducing bycatch in the New Zealand scampi fishery, including some general thoughts on the experimental design of field trials. To describe any effects of fishing that might modify bentho-pelagic coupling (a complex, interlinked suite of processes transferring energy, oxygen, carbon, and nutrients between pelagic and benthic systems), to consider the scale of such possible effects, and to put the summary in a New Zealand context. 1. To design a programme in New Zealand waters previously trawled and now closed to trawling to monitor the rate of regeneration of benthic communities on seamounts. 1. To carry out a survey and determine the distribution and absolute abundance of pre-recruit and recruited oysters in both non-commercial and commercial areas of Foveaux Strait. The target coefficient of variation (c.v.) of the estimate of absolute recruited abundance is 20%. 2. To estimate the sustainable yield for the areas of the commercial oyster fishery in Foveaux Strait for the year 2002 oyster season. 3. To identify and count benthic macro-biota collected during the dredge survey. 1. To determine the spatial extent, nature and impact of mobile bottom fishing methods within the New Zealand EEZ. 347 Completed Tracey et al. 2005 Completed Hartill et al. 2006 Completed Cryer et al. 2004 Completed Clark & O'Driscoll 2003; Clark & Rowden 2009 Completed Rowden et al. 2007 Completed Cryer and Hartill 2002; Baird et al. 2002 Objectives unknown Completed Booth et al. 2002; Beentjes & Baird 2004
