Catching fish is not inherently bad for the ocean, except for when vessels catch fish faster than stocks can replenish, this is called 'overfishing'. Overfishing is one of the most significant drivers of declines in ocean wildlife populations. The number of overfished stocks globally has tripled in half a century, and today, one third of the world’s assessed fisheries are currently pushed beyond their biological limits.
Overfishing also threatens whales, dolphins and cetaceans in general. Many of them die each year by entanglement in fishing gear, and overfishing in a certain area results in a vast reduction in the amount of fish available for animals to feed on.
What can be done to stop overfishing?
Many solutions can be taken to tackle the problems of overfishing, such as:
- Create more marine protected areas meaning: More no-catch zones must be established to allow fish populations and their ecosystems to recover and replenish themselves to ensure fishing for future generations.
- Worldwide catch shares: catch shares is a system of fishing management that is proven to allow fish stocks to replenish while saving the livelihood of fishing communities by preventing a sudden collapse.
