Abstract
The most important controversy in fisheries management in recent years has been the debate over marine protected areas (MPAs). The epicentre of this controversy is the issue of whether large networks of no-take MPAs (NTMPAs), more usually known as marine reserves (MRs), are necessary to protect fish stocks. On the one hand, advocates of MRs argue that without MRs the worldwide decline in fish stocks will continue to the point of threatening more stocks with extinction. On the other hand, critics of MRs argue that conventional fisheries management (CFM) which includes restrictions on quota, fishing gear, effort controls, and selective spatial restrictions, if properly enforced, is perfectly adequate to protect fish stocks. There is another element in this controversy—which concerns marine biodiversity. Advocates of MRs argue that the only way to protect non-target marine species and their habitats (biodiversity) is to establish large networks of MRs; whereas critics of MRs argue that biodiversity can be adequately protected by CFM together with some selected MRs.

According to some, this is likely to be an underestimate. Pauly and Froese (2012) suggested that 37 % of fish stocks yield less than 10 % of their historic maximum catches.

For example at the end of the marine conservation zone (MCZ) planning process, the famous broadcaster Sir David Attenborough, vice president of the Wildlife Trusts said “I urge the government to designate the full list of 127 sites now, for day by day the wildlife in these sites is being destroyed and damaged. Time is running out for us to save our fragile seas”. http://www.independent.co.uk/environment/nature/attenborough-issues-plea-to-save-our-seas-7834223.html.

Indeed, the findings of many of these high impact studies have been alleged to be grossly misleading: “Closer inspection of this litany of papers shows them to be either outright wrong or serious distortions of reality” (Hilborn 2007d, p. 297).
