New research has pinpointed four high-traffic areas in the Pacific Ocean that should be considered of high priority if conservation efforts focused on large pelagic fishes such as tuna, blue marlin and swordfish are to be successful.
Research produced by current and past members of the Sea Around Us has been included in what
is being described as “a definitive volume on large marine ecosystems.”
The book, titled Ocean
sustainability: Assessing and managing the world’s large marine ecosystems,
presents best assessment and management practices based on examples from 37
years of published peer-reviewed papers on large marine ecosystems or LMEs.

Despite their odd shape, which makes them resemble a tuft of seaweed, common and leafy seadragons grow in the same fashion as other bony fish, new research has found.
The inconspicuous sea sponges are Earth’s oldest multicellular animals and have filtered the oceans for nearly 900 million years, long before the first plants appeared on land. New research appearing in the journal Fisheries Bulletin, published by the National Oceanic and Atmospheric Administration, indicates that their growth depends on their oxygen supply in a manner similar to more complex animals such as fish.

Conserving marine biodiversity, avoiding species extinction and maintaining food security from wild capture fisheries can all be achieved simultaneously if a global, non-regionalized approach to marine spatial management is undertaken by the signatories of IUCN Resolution 50, which calls for the protection of 30 per cent of the ocean by 2030.
