Whale, dolphins and sea birds ID cards
PIRFO Whales, dolphins and sea birds ID cards for Pacific Islands Regional Fisheries Observers Prepared by the Pacific Community Noumea, New Caledonia, 2016 © Pacific Community, 2016 These identification cards are produced by the Pacific Community (SPC) to help with the identification of species of special interest (protected species) encountered by Fisheries Observers while onboard commercial tuna boats that fish in the western and central Pacific Ocean (WCPO). The species included in these cards are the ones commonly recorded by observers on tuna vessels operating in the WCPO. The cards can be easily accessed by observers while working on deck during fishing operations to verify and correctly identify species. The cards also assist in training observers operating within the Western and Central Pacific Fisheries Commission Convention Area. Printing of these cards was made possible through financial assistance provided by the Japan Trust Fund. This project was coordinated by SPC’s Oceanic Fisheries Programme Fisheries Monitoring Section and Fisheries Information Section. Colour illustrations by Hazel Adams (p. 4-8), Youngmi Choi (p. 11-38); black and white illustrations courtesy of the Food and Agriculture Organization of the United Nations (FAO). This publication is based on the Marine species identification manual for horizontal longline fishermen by Chapman et al. (2006). First published – 2006.
