1. To provide an updated database that identifies all known seamounts in the
“New Zealand region”, encompassing the area from 24o00’ – 57o30’S, 157o00’E
– 167o00’W. The database will catalogue relevant data (e.g. physical, biological,
location, fishing effort) for individual seamounts.
2. To identify indicators and measures suitable for the assessment of risk
pertaining to the effects of fishing disturbance on the benthic biota of seamounts,
and review suitable ecological risk assessment methods, that can be derived or
utilise information contained within the seamount database.
1. To monitor changes in fauna and habitats over time on selected UTFs in the
Chatham Rise area that have a range of fishing histories.
2. To continue development of the risk assessment model to predict the effects
of fishing, and provide options for the management of UTF ecosystems.
1. To estimate the quantity of non-target fish species caught, and the target and
non-target fish species discarded, in the trawl fisheries for jack mackerel for the
fishing years 20011/2002 to 2004/05 using data from Mfish observers and
commercial fishing returns.
1. To estimate the quantity of non-target fish species caught, and the target and
non-target fish species discarded, in the trawl fisheries for orange roughy for the
fishing years 1999/2000 to 2003/04 using data from Scientific Observers and
commercial fishing returns.
