1. To assess the likely performance of different bycatch control rules for the
SQU6T fishery.
2. To correct and update the Breen-Fu-Gilbert (2008) sea lion model- including
assessment of the performance of 200-series and 300-series management
control rules.
3. To document the development of the model- including all four objectives of
project IPA2006/09 and objective 1 of this project- in a single report suitable for
an international review.
Necropsy of marine mammals captured in New Zealand fisheries in the 2007-08
fishing year
To provide an asessment of the risk posed by different fisheroes to the viability of
NZ protected species- and to assign a risk category to all NZ fishing operations
1. Estimate capture rates per unit effort and total captures of seabirds for the
New Zealand EEZ and in selected fisheries by method, area, target fishery, in
relation to mitigation methods in use, and, where possible, by seabird species for
the fishing year 2006/07, 2007/08 and 2008/09.
2. Examine the incidence of seabird warp strike in trawl fisheries where these
data are available from fisheries observers, and estimate the rate of incidents
(birds affected per hour) and total number of seabirds affected by fishery, area
and method. Examine the factors (fishery, environmental, seasonal, mitigation,
area) that influence the probability of warp-strike occurring.
