The sea floor can grow back.

Blue Meridian Ocean Trust replants seagrass, lifts lost nets out of the water and agrees fishing rules with the people who fish — across the Mediterranean, from Marseille.

A registered marine conservation charity, founded in 2011.

What the work adds up to

We measure in hectares, tonnes and euros, and we report the figures as they stand. These are ours.

  • 640ha

    of seagrass replanted on Mediterranean sea floor that had lost its meadows.

  • 212t

    of ghost nets cut free and brought ashore, so they stop fishing for no one.

  • 14

    active projects running across the Mediterranean right now.

  • 91%

    of every euro you give goes to the field — divers, boats, seedlings and the people who do the work.

Three programmes, one sea floor

Each one repairs a different kind of damage. Together they give a stretch of coast a real chance to recover — and to stay recovered.

Seagrass restoration

Seagrass meadows hold the sea floor together and shelter young fish. Where anchors and trawls have torn them out, our teams replant them by hand, shoot by shoot.

640 hectares replanted so far.

How it works

Ghost-net removal

Lost and abandoned nets keep fishing long after anyone hauls them in, catching fish, turtles and seabirds. We locate them, cut them free and bring them ashore.

212 tonnes removed to date.

How it works

Community fishing agreements

Recovery lasts when the people who fish a coast decide together how to share it. We sit down with fishing communities and help them write agreements on where, when and how to fish, so restored meadows and stocks can hold.

How it works

One sea, worked from Marseille

Our office is in Marseille. Our boats, divers and partners work across the whole Mediterranean, where fourteen projects are active today.

Other ways to give

Where each euro goes

Ninety-one cents of every euro reach the field. The rest keeps a registered charity running properly: accounts, governance and the work of raising the next euro.
