The goal in brief

GoalEvery fish stock rebuilt to a healthy size and fished within sustainable limits.

of fish stocks at sustainable levels (2023)1
62.4%
people get 1/5+ of animal protein from fish2
3.1 billion
oceanic sharks and rays since 19704
−71%

Why it matters

Only 62.4% of the world’s assessed ocean fish stocks were at sustainable levels in 2023, down from 64.5% two years earlier.1 Seafood supplies at least a fifth of the animal protein eaten by 3.1 billion people,2 so shrinking fish populations put food and jobs at risk around the world.

How we’ll know it’s done

Finish line
Every assessed fish stock at or above the size that gives its maximum sustainable catch, the benchmark in SDG target 14.4.3
What counts
A stock whose numbers have actually rebuilt, not just one where catches are holding steady.
How it’s checked
FAO’s global review of fish stocks, which reports the UN’s sustainable-stocks indicator every two years.
Our part
We’ll fund this once our vetting team vets an organization working on it.

What follows

  • More seafood for families who depend on it for protein.H-01Eliminate global hunger and malnutrition
  • Steadier incomes for fishing communities.H-02End poverty
  • Sharks, turtles and seabirds recovering as overfishing and bycatch ease.W-01Protect endangered and critical species
  • Healthier reefs and kelp forests, where fish help keep the system in balance.O-06Protect and regenerate key ocean ecosystems
  • A fuller, more resilient ocean overall.O-05Protect and regenerate 100% of the world’s oceans

How it can be solved

The approaches to this goal, and how many of the organizations taking each one we’ve vetted.

  • Community fisheries

    Helping fishing communities manage their own waters so fish can recover.

    2 organizations

  • Bycatch reduction

    Cameras and lights that help keep unwanted species out of nets.

    1 organization

  • Restocking

    Breeding and releasing fish to rebuild depleted populations.

    1 organization

Who’s working on it

We only call a solution proven, measurable and scalable once our vetting team has vetted it. Everything else here, the team is tracking.

Vetted0 organizationsReviewed by our vetting team, and passed all three tests.

  • Proven

    It has worked, with results to show.

  • Measurable

    Its impact can be counted.

  • Scalable

    It can grow toward the size of the goal.

None on this goal yet. When our vetting team vets an organization working on it, it appears here with its vetting report.

Not vetted4 organizationsTracked by our vetting team. Not vetted yet, so we make no claims about them.

Listing an organization isn’t an endorsement. Not vetted means just that: our vetting team is tracking it, and we make no claims about it yet. Last reviewed October 2026.
