PACIFIC TUNA & CLIMATED TRENDS & FORECASTS

摘要

Most models to assess tuna populations have been largely based on catch report data notwithstanding the fact that climate change also affects the stock and its location. With a new method developed by scientists at Collecte Localisation Satellites (CLS), working with the Secretariat of the Pacific Community (SPC), it is now possible to forecast changes in stocks as well as simulate fishing effort scenarios based on the latest climate and oceanography data. This article explains how, using the method, the impact of global warming on tuna can be predicted, and asserts that some tuna species can adapt to climate change provided fishing efforts are kept within sustainable levels.
