Sharks and other large predators play an important role in the health of our ocean. But in the last century, we’ve taken out an ashtonishing 67 percent them. Our oceans are changing rapidly, and will continue to change if we keep taking out the key species that play such an important roles in their health.

The volume by weight of smaller fish has more than doubled in the past century. The biggest increases are to be found in those fish that are less popular with humans, such as sticklebacks and gobies,  research found.
Despite the flourishing small fish populations, scientists are concerned. “This should be a warning bell for the rest of the world. We are still fishing way too much,” said Professor Villy Christensen, lead author of a research paper of the University of British Columbia. He states predators are important for maintaining healthy ecosystems. Fisheries have industrialized dramatically, but the drastic reduction in big fish in recent decades is great news for the smaller prey fish such as pilchards, herrings, sprats and caplin because it has significantly increased their chances of survival. The decline in predators has shored up supplies of once dwindling small fish – including anchovies and sardines – for decades to come.

Everywhere where large predators are taken out to satisfy the world’s endless appetite for tasty tuna, shark fin soup and other dishes, the environment changes.
