This article talks about how important it is to manage fishing in a way that keeps the environment healthy while helping local fishing communities on small islands like Tenerife. The researchers worked with local fishers to understand the challenges they face, like too many fish being caught, problems regulating fishing groups, and a rise in illegal fishing. They found that to make fishing sustainable, rules need to be adapted to fit the local needs better, create protected areas, and encourage more cooperation between scientists and fishers. The goal is to balance protecting the marine environment and helping the island's fisher communities grow.
