Seabird, marine mammal, and turtle bycatch

We developed an interactive website to present data on seabird, marine mammal, and turtle bycatch in New Zealand waters for the Ministry for Primary Industries.

To monitor the impacts of commercial fishing on seabirds, marine mammals, and turtles, government observers on fishing vessels record any catch incidents that occur. Data on the capture of these protected species in trawl and longline fisheries from 2002 onwards are available here.

Seabird counts around fishing-vessels

We created an interface for this dataset of the number of seabirds observed around fishing vessels in New Zealand, collected by the Department of Conservation.

New Zealand is a global centre of seabird diversity, with over 80 species breeding either on the mainland or on offshore islands. New Zealand fisheries observers record the number of seabirds around fishing vessels. These observer data are unique record of the distribution of seabirds in the New Zealand region.

New Zealand sealion tag-resight data

We created an interface for this dataset of New Zealand sealion tagging records, collected by the Department of Conservation.

The Department monitors the New Zealand sea lion population, which numbers approximately 10,000 individuals. Tagging and resighting studies of sea lions in the subantarctic are carried out as part of the monitoring programme to better understand sea lion demographics.
