The danger becomes dual, says Danson: "If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system".
If the target species is especially valuable or slow-growing, overfishing (at least in narrow economic terms) is rational.
Overfishing at coastal zones around the globe has fundamentally changed market availability and cost.

Although individual nations were already protecting manta rays, the fish often migrate through unregulated waters, putting them at increased risk from overfishing.
The L index enabled us to quantify the ecosystem overfishing risks at a global scale caused by removing target and non-target species spanning from lower to higher trophic levels by accounting for both bottom-up (primary productivity) and top-down (fishing pressure) effects.
The system is aimed at reducing the threat of overfishing.
