Divers' help needed mapping seagrass with app New research shows that a fifth of the world's biggest fisheries depend upon healthy seagrass meadows. The meadows are also extremely important for small-scale fisheries. Seagrasses are marine flowering plants that form extensive meadows in shallow seas on all continents except Antarctica. A new study, by scientists at Cardiff and Stockholm Universities, concludes that seagrasses should be recognised and managed to maintain and maximise their role in global fisheries production. In the Mediterranean, for example, seagrass covers less than 2% of the sea floor, but seagrass-associated fish and invertebrate species comprise 30%-40% of the total value of commercial fisheries landings. One of the author's of the study, Dr Leanne Cullen-Unsworth, says: "Seagrass meadows support global fisheries productivity by providing nursery habitat for commercial fish stocks such as tiger prawns, conch, Atlantic cod and white spotted spinefoot". 
Seagrass meadows are currently experiencing rapid decline with loss estimated at around 7% of their global distribution annually How you can help There is now an app for mapping Seagrass. You can become a citizen scientist and contribute to marine conservation with just a few taps of your phone. Get along to Seagrass Spotter and make your contribution.

Rising water temperature, changing salinity and oxygen levels, and human activity, are all adding to the strain on sea life, with the report claiming that 35 per cent of the fauna found in the Arabian Gulf in 2010 will become extinct over the next 62 years. | |  | How ocean pollution affects marine wildlife
Around 1.4 billion pounds of garbage is dumped into the ocean every year, which along with other sources of pollution, including sewage, industrial waste, and oil spills, kills over a million seabirds and 100,000 sea mammals every year. | | |
