TLDR
Using 58 datasets from 19 European marine reserves, it is shown that reserve size and age do matter: Increasing the size of the no-take zone increases the density of commercial fishes within the reserve compared with outside; whereas thesize of the buffer zone has the opposite effect.Abstract:
Marine reserves are widely used throughout the world to prevent overfishing and conserve biodiversity, but uncertainties remain about their optimal design. The effects of marine reserves are heterogeneous. Despite theoretical findings, empirical studies have previously found no effect of size on the effectiveness of marine reserves in protecting commercial fish stocks. Using 58 datasets from 19 European marine reserves, we show that reserve size and age do matter: Increasing the size of the no-take zone increases the density of commercial fishes within the reserve compared with outside; whereas the size of the buffer zone has the opposite effect. Moreover, positive effects of marine reserve on commercial fish species and species richness are linked to the time elapsed since the establishment of the protection scheme. The reserve size-dependency of the response to protection has strong implications for the spatial management of coastal areas because marine reserves are used for spatial zoning.read more

TL;DR: The results show that global conservation targets based on area alone will not optimize protection of marine biodiversity, and more emphasis is needed on better MPA design, durable management and compliance to ensure that MPAs achieve their desired conservation value.

TL;DR: It is suggested that reserve characteristics and context play key roles in determining the direction and magnitude of the reserve response, validating the potential for well designed and enforced reserves to serve as globally important conservation and management tools.

Designing marine reserve networks for both conservation and fisheries management
TL;DR: This work presents size, spacing, location, and configuration guidelines for designing networks that simultaneously can enhance biological conservation and reduce fishery costs or even increase fishery yields and profits.

TL;DR: It is reported that many MPAs failed to meet thresholds for effective and equitable management processes, with widespread shortfalls in staff and financial resources; continued global expansion of MPAs without adequate investment in human and financial capacity is likely to lead to sub-optimal conservation outcomes.

BOFFFFs: on the importance of conserving old-growth age structure in fishery populations
TL;DR: Mark A. Hixon et al. as discussed by the authors proposed a method to identify the most likely species for a particular species of fish in the Pacific Ocean, based on the results of a study conducted at the University of Hawaii at Mānoa.

TL;DR: Paleoecological, archaeological, and historical data show that time lags of decades to centuries occurred between the onset of overfishing and consequent changes in ecological communities, because unfished species of similar trophic level assumed the ecological roles of over-fished species until they too were overfished or died of epidemic diseases related to overcrowding as mentioned in this paper.

TL;DR: Zoning the oceans into unfished marine reserves and areas with limited levels of fishing effort would allow sustainable fisheries, based on resources embedded in functional, diverse ecosystems.
