"When fish are taken from our oceans faster than they can reproduce, their
population numbers decline. This over-fishing upsets marine ecosystems. It’s
also bad for human populations that rely on fish for protein in their diets.
To manage fishing areas sustainably, we need accurate data on how many fish
exist and how abundant they will be in future. Fisheries scientists use complex
mathematical models to determine this.
But an investigation by my colleagues and I, published today in the journal
Science, casts serious doubt on the accuracy of these models.
We studied 230 fisheries around the world. We found populations of many
overfished species are in far worse condition than has been reported, and the
sustainability of fisheries was overstated. Urgent action is needed to ensure
our oceans are not fished below their capacity to recover."
