Declining Pacific shark population alarms concervationists
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. Clarke and other scientists in the western North Pacific, heighten concerns for the sustainability of Pacific shark populations. "Our research reveals alarming declines of 17% per year in populations of the oceanic whitetip shark, a species highly valued for its fins," explained Dr. Clarke. " Also of serious concern are declines of 5% per year for North Pacific blue sharks, considering that this species is known as one of the most productive a...
