In October 1999, MPA News surveyed a dozen MPA experts from around the world on what scientific question intrigued them most (MPA News 1:2). Reflecting the relative newness of MPA science, respondents viewed some of the most basic questions -- such as whether no-take areas increase stock biomass, both within and outside their borders -- as unanswered.
Since then, several academic papers, reports, and consensus statements have cited "compelling" scientific evidence for marine reserves' use as a central tool in fisheries management. A committee of the US National Research Council has argued in favor of the expanded use of marine reserves for protecting and rebuilding depleted fish stocks (see box at end of article). A separate group of 160 marine-science academics voiced a similar opinion (MPA 2:8).
