Chatham Albatross

Species
Thalassarche eremita

Chatham albatross are caught in a variety of longline and trawl fisheries in the southeast Pacific Ocean.  Known mortality from bycatch has been observed in ling demersal and tuna pelagic longline fisheries (Robertson et al 2004) and hake and orange roughy trawl fisheries in the New Zealand Exclusive Economic Zone (EEZ) (Baird 2004a; 2004b).

Distribution
Southeast Pacific; breeds only in a small area of the Chatham Islands of New Zealand
Population
Around 5,000 breeding pairs
IUCN Status
Critically Endangered
Type
Bird
Bycatch Threat
Longlines and trawls

How to Use the Database

The Database Includes:

  • Citations for studies that pertain to bycatch reduction approaches.
  • Summaries of the findings for each study.
  • Descriptions of bycatch reduction techniques.
  • Descriptions of fishing methods.
  • Links to studies and study authors, where available.

How to Search:

Users can search the database by fishing gear, bycatch reduction technique, or non-target wildlife group singly or in combination. This is achieved by selecting items from the drop-down menu on the initial search page.
