Objectives unknown Completed Taylor 1992
1. To estimate the quantity of non-target fish species caught, and the target and
non-target fish species discarded in the specified fishery, for the fishing years
since the last review, using data from Ministry of Fisheries Observers and
commercial fishing returns.
2. To compare estimated rates and amounts of bycatch and discards from this
study with previous projects on bycatch in the specified fishery.
3. To compare any trends apparent in bycatch rates in the specifiedfishery with
relevant fishery independent trawl surveys.
4. To provide annual estimates of bycatch for nine Tier 1 species fisheries and
incorporate into the Aquatic Environment and Biodiversity Report specified in
Objective 3 for SQU, SCI, HAK, HOK, JMA, ORH, OEO, LIN, SBW
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 oreos for the fishing
years 2002/03 to 2008/09 using data from Scientific Observers and commercial
fishing returns.
2. 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 2004/05 to 2008/09 using data from Scientific Observers and
commercial fishing returns.
1. To complement the field identification guide under IDG2006/01 with the
remaining 120 fish species caught by commercial fishers in New Zealand waters
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 southern blue whiting
for the fishing years 2002/03 to 2006/07 using data from Scientific Observers
and commercial fishing returns.
Estimates of the catch of non-target fish species, and the discards of target and
non-target fish species in the hoki (Macruronus novaezelandiae), hake
(Merluccius australis), and ling (Genypterus
blacodes) trawl fisheries for the fishing years 2003–04 to 2006–07 using data
from Scientific Observers and commercial fishing returns
1. To determine the growth rate, age at maturity, longevity and natural mortality
rate of shovelnose dogfish (Deania calcea) and leafscale gulper shark
(Centrophorus squamosus).
