Cautious fish evolve out of marine reserves

New research supports the creation of more marine reserves in the world’s oceans because, the authors say, fish can evolve to be more cautious and stay away from fishing nets.

The research suggests that by creating additional “no-take” areas, some fish will stay within marine reserves where they are protected from fishing. While other fish will move around the ocean, these less mobile fish will continue to live in the protected areas, pass this behaviour on to their offspring, and contribute to future generations, increasing the overall stock.

“Fisheries-induced evolution” is the key concept behind these findings. “Even for fish like tuna and sharks that spend a lot of time far from shore, marine reserves are an important conservation tool,” said Jonathan Mee, lead author of the study and a faculty member at Mount Royal University who conducted this research while completing a postdoctoral fellowship at UBC. “We used mathematical modelling to find out under what conditions marine reserves might push fish to evolve to escape capture.”

In a collaboration between UBC’s Biodiversity Research Centre and the Sea Around Us project at the Institute for the Oceans and Fisheries, researchers modeled the movements of skipjack and bluefin tuna and great white sharks in the ocean.

They found evidence that within 10 years of creating new marine reserves, the movement pattern of tuna could change while it would take up to five decades for the longer-living great white shark to change. They also found evidence that the greater the fishing pressure close to the reserves, the faster the fish would evolve to stay in the protected space.

The researchers argue there is a need to create more marine reserves because fishing operations have grown exponentially in recent decades, leading to a global catch decline of 1.2 million tonnes of fish per year.

“The boats got bigger and now we can cover the entire range of the tuna. The distance doesn’t protect them, depth doesn’t protect them, nothing protects them except our decision to remove ourselves from certain areas in the form of marine reserves,” said Daniel Pauly, principal investigator of the Sea Around Us project and a co-author of the study. “A well-controlled marine reserve would, at least in part, protect against the effect of overfishing outside the reserve.”

These findings, adds Sarah Otto from UBC’s Biodiversity Research Centre, show to fisheries managers, conservation planners, environmentalists and professionals in the fishing industry that “marine reserves are likely more effective than previously thought in preventing extinction for some species, protecting biodiversity and even acting as an insurance policy.”
