Research published today in the journal Conservation Biology presents the most comprehensive assessment of the status of Pacific shark populations to date. The paper, authored by Dr. Shelley Clarke and a team from the Secretariat of the Pacific Community in New Caledonia, shows significant declines in catch rates for blue, mako, and oceanic whitetip sharks, as well as declining average sizes of oceanic whitetip and silky sharks, indicating heavy fishing. These results, along with evidence of shark targeting reported by Dr.
Many shark populations have plummeted in the past three decades as a result of excessive harvesting – for their fins, as an incidental catch of fisheries targeting other species, and in recreational fisheries. This is particularly true for oceanic species. However, until now, a lack of data prevented scientists from properly quantifying the status of Pacific reef sharks at a large geographic scale.
