Fisheries Story: Fat is a sign of good health for Tuna


Do you know what a Fatmeter is? It is an electronic device to measure the amount of fat present. It has been used over the past 10 years by the SPC Fisheries scientist team to measure fat content in individual tuna. Simple and quick, the scientist just presses the probe on the fish and it tells its fat content, which is a good index of tuna health.

This week, 450 new measurements have been incorporated in the SPC biological database ‘Biodasys’, a collaboration between database managers, scientists, collection supervisors and biological samplers to ensure a high level of data quality for biological samples taken in the Western Central Pacific Ocean.

SPC database now contains more than 5,400 fat measurements for the 4 main tuna species and will soon be analysed by some of our scientists.
