Tuna important for public health in Pacific: study

Xinhua, February 2, 2015 Adjust font size:

In the ongoing battle against obesity, heart disease and diabetes in the Pacific region, a new study reveals that allocating sufficient tuna for local consumption and keeping it affordable could significantly improve health outcomes, the Secretariat of the Pacific Community said Monday.

"Pacific Island communities have the highest rates of obesity and diabetes in the world, primarily because traditional foods such as root crops, fish and shellfish are being replaced by relatively cheap, energy-dense and nutritionally-poor imported foods," and "Increased consumption of fish and shellfish, which are rich in protein, essential fatty acids, vitamins and minerals, is seen as an important part of the solution," the secretariat said in a statement.

The study, published in the journal, Marine Policy, found that by 2020, people in the 22 Pacific Island countries and territories will need 268,000 tonnes of fish annually for food security, increasing to 344,000 tonnes by 2035. Current total fish consumption is around 210,000 tonnes per annum, and most of this fish is caught from coral reefs.

However, coastal fisheries based on coral reefs in many Pacific Island countries and territories do not have the capacity to produce more fish. In fact, there will be fewer reef fish per person as human populations increase.

"A gap is emerging between how much fish can be harvested sustainably from well-managed reefs and the quantity of fish recommended for good nutrition," said Moses Amos, director of the Secretariat of the Pacific Community's Fisheries Aquaculture and Marine Ecosystems Division.

"The gap will increase dramatically in some countries in the years ahead. This study shows how the rich tuna resources of the region can be used to fill the gap and supply the fish needed for healthy diets, " Amos said.

The study involved fisheries and health experts from the Secretariat of the Pacific Community, the Conservation International, University of Wollongong, the WorldFish, the Pacific Islands Forum Fisheries Agency and some other organizations. Endi
