A third of fish stocks are overfished

Biologically sustainable vs overexploited — FAO tracks the split.

Biomass grids are about weight on Earth, not headcount — a whale and a mouse can share a color family but not a cell count story. This grid divides marine fish stocks (2026 snapshot) into colored bands — Overfished, Fished at max sustainable, and Underfished — using equal squares so you compare shares, not country size on a map.
