A new report by American and Canadian researchers published in the journal Science predicts the loss of all fish and seafood species by 2048. The data collected strengthens the link between protection being granted to ocean areas and the restoration of fish species.
It is never too late to try to change the current policies on (over)fishing.
Experiments performed in small, relatively contained ecosystems show that reductions in diversity tend to bring reductions in the size and robustness of local fish stocks. This implies that loss of biodiversity is driving the declines in fish stocks seen in the large-scale studies.
The final part of the jigsaw is data from areas where fishing has been banned or heavily restricted.
These show that protection brings back biodiversity within the zone, and restores populations of fish just outside.
