‘Nursery Of Tuna’: Coral Triangle - Needs Protectionff

The survival of species critical to the livelihoods of millions - such as those in the “nusery grounds” of the Coral Triangle - is being called into question in the wake of the IUCN’s warning this week of a mass global extinction unseen for 65 million years.

The warning was issued during the World Conservation Congress in Barcelona, as the IUCN issued the latest update in its Red List of threatened species. 

The IUCN has for the first time assessed all 161 species of grouper, a reef fish which makes up a large part of the  lucrative live fish trade in the Coral Triangle, which spans Malaysia, Indonesia, the Philippines, Papua New Guinea, the Solomon Islands and Timor Leste, and contains 75 per cent of the world’s coral species, as well as critical spawning grounds for globally valuable species such as tuna and reef fish.

Resource depletion rates in the Coral Triangle are high and accelerating due to the explosive growth of Asian fish markets and the insatiable demand for tuna and shrimp in the US, Europe and Japan.

Local demand for food and space is also adding to global pressures and enhancing the risk of instability and insecurity. This is further compounded by the impacts of climate change and destructive fishing techniques, such as the use of explosives or cyanide to catch reef fish.

”Coastal development, destructive fishing and overfishing, unsustainable tourism and climate change are taking a heavy toll and, if left unchecked, will cause the collapse of the world’s most remarkable coral reef ecosystem,” said Dr Lida Pet Soede, head of WWF’s Coral Triangle Programme.

”The implications of loss of habitat and natural resources in the Coral Triangle are enormous in terms of the impact on ocean life globally and on regional livelihoods. This ‘nursery of the seas’ supports global populations of turtles and tuna, while 180 million people depend on its coasts and coastal resources for food security.”

The IUCN also lists other Coral Triangle species at risk of extinction, such as green turtles (Endangered), hawksbill turtles (Critically endangered) and scalloped hammerheads (Near threatened).

“The Coral Triangle is the world’s centre of marine life, on a par with the Amazon Rainforest or the Congo Basin in terms of its importance to life on Earth. We need to recognise that the same level of threat exists in our oceans as it does on the land,” said Dr Pet Soede.

WWF’s Coral Triangle Programme has goals for 2020 of protecting 10 per cent of priority coral reefs in the region, zero decline in sea turtle populations from 2007 levels, and reversing the degradation of the area’s marine resources, including turtles, tuna and reef fish.
