Movements of adults and juveniles beyond MPA boundaries
As fishes and invertebrates become more abundant inside a marine reserve, some adults and juveniles may leave the marine reserve to live in less crowded areas elsewhere. They also may leave because they need a different habitat as they grow or because they reproduce in a specific place outside the reserve. This 'spillover' of adult and juvenile fishes and invertebrates can contribute to marine populations living in fished waters outside reserves, where they can benefit fisheries.
The graph to the left shows how far different fish species (which had been tagged inside a marine reserve) traveled from the reserve - in some cases up to hundreds of miles.
