Overview

Overall Objective:

Estimate the spatial density of Hector’s dolphins, including seasonal variability, for local populations of particular interest for fisheries management, and evaluate the consequences for estimation of fisheries risk.

Specific Objectives:

1. Identify and compile data potentially indicative of Hector’s dolphin spatial distributions in up to three local populations or local habitats of particular interest.

2. Applying an appropriate spatial modelling statistical method, estimate the spatial density of Hector’s dolphins in the local area(s) of interest, including seasonal variation.

3. Intersect predicted spatial densities under Objective 2 with fishing effort data to estimate spatial overlap and fisheries risk, including changes over time, in the local population(s) of interest. In consultation with Fisheries New Zealand working groups, test alternate structural assumptions potentially affecting estimation of fisheries risk.

4. Using model sensitivities, test the extent to which the spatial distribution(s) from Objective 2 and the estimates of overlap/ risk from Objective 3 are sensitive to alternate plausible model parameterisations.
