“…At the same time conservationists have been pushing for new ocean reserves, marine scientists have documented that fully protecting large areas can have spillover effects by boosting fish populations. Some fish travel outside these areas and can be caught, making these restrictions more politically-palatable to local residents.

National Geographic explorer in residence Enric Sala, author of the new book “Pristine Seas: Journeys to the Ocean’s Last Wild Places,” calls these regions “fish banks,” in which fishing operators can draw down the interest without depleting the capital.
