trawl fisheries
1. To estimate growth, longevity, rate of natural mortality, and length at maturity
of four key rattail bycatch species in New Zealand trawl fisheries.
2. To examine data from trawl surveys and other data sources for trends in catch
rates or indices of relative abundance for species in Objective 1.
1. To monitor the abundance of deepwater sharks taken by commercial trawl
fisheries
To estimate the quantity of non-target fish species caught, and the target and
non-target fish species discarded, in the longline fisheries for ling for the fishing
years 1998/99 to 2005/06 using data from MFish Observers and commercial
fishing returns.
1. To produce a field guide for fish species in New Zealand
2. To produce a field identification guide for all QMS and other fish species
commonly caught in commercial and non-commercial fisheries
1. To estimate the catches, catch rates, and discards of non-target fish in tuna
longline fisheries data from the Observer Programme and commercial fishing
returns for the 2005/06 fishing year.
2. To describe bycatch trends in tuna longline fisheries using data from this
project and the results of previous similar projects.
To estimate the catch rates of non-target fish in the 10ngline fisheries for tuna
using data from the Observer Programme and commercial fishing returns for the
2002/03, 2003/04 and 2004/05 fishing years.
2. To estimate the quantities of non-target fish caught in the longline fisheries for
tuna using data from the Observer Programme and commercial fishing returns
for the 2002/03, 2003/04 and 2004/05 fishing years.
3. To estimate the discards of non-target fish caught in the longline fisheries for
tuna using data from the Observer Programme and commercial fishing returns
for the 2002/03, 2003/04 and 2004/05 fishing years.
4. To describe trends in the non-target fish catches in the tuna longline fisheries
using data from this project and the results of previous similar projects.
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.
