There are two approaches to ensuring the sustainability and biodiversity of fisheries: One is the use of catch limits, as is currently practiced, and the other is the setting up of marine reserves to protect stocks. The introduction of reserves has been hampered by a lack of information of relative yields from the two systems. Hastings and Botsford (p. 1537) used a simplifying set of assumptions to show that yields are similar and that, under some circumstances, marine reserves offer significant advantages over catch quotas.
