“…Our estimates of spillover distance are consistent with studies of large-scale partial-protection marine protected areas that find even greater spillover distances (Murawski et al 2005), with studies of adult movement patterns showing similar or greater distances of movement across reserve boundaries (for example (Samoilys 1997;Kelly & MacDiarmid 2003;Topping et al 2005), and with estimates from spillover studies that did not meet our inclusion criteria (Abesamis & Russ 2005;Goni et al 2008;Harmelin-Vivien et al 2008;Williams et al 2009). However, in all of these cases, spillover acts at relatively small scales such that single reserves cannot sustain entire fished stocks (through spillover alone; they may be able to provide this service through larval export).…”

Spillover from marine reserves and the replenishment of fished stocks

SUMMARYNo-take marine reserves are widely recognized as an effective conservation tool for protecting marine resources. Despite considerable empirical evidence that abundance and biomass of fished species increase within marine reserve boundaries, the potential for reserves to provide fisheries and conservation benefits to adjacent waters remains heavily debated. This paper uses statistical and population models to evaluate published empirical data on adult spillover from marine reserves and shows that spillover is a common phenomenon for species that respond positively to reserve protection, but at relatively small scales, detectable on average up to 800 m from reserve boundaries. At these small scales, local fisheries around reserves were likely unsustainable in 12 of 14 cases without the reserve, and spillover partially or fully offsets losses in catch due to reserve closure in the other two cases. For reserves to play a role in sustaining and replenishing larger-scale fished stocks, networks of reserves may be necessary, but as few exist this is difficult to evaluate. The results suggest reserves can simultaneously meet conservation objectives and benefit local fisheries adjacent to their boundaries.

“…To assess potential demographic effects of the mortality, count data for puffer fish were obtained from long-term survey data collected for the West Hawaii Aquarium Project (Williams et al 2009). Since 1999, this project has systematically surveyed the same 23 sites on the west coast of the island of Hawaii 4 to 6 times yr −1 and thus has the most complete long-term demographic data for reef fish in the Hawaiian Islands.…”

Fish die-offs are important signals in tropical marine ecosystems. In 2010, a mass mortality of pufferfish in Hawaii (USA) was dominated by Arothron hispidus showing aberrant neurological behaviors. Using pathology, toxinology, and field surveys, we implicated a series of novel, polar, marine toxins as a likely cause of this mass mortality. Our findings are striking in that (1) a marine toxin was associated with a kill of a fish species that is itself toxic; (2) we provide a plausible mechanism to explain clinical signs of affected fish; and (3) this epizootic likely depleted puffer populations. Whilst our data are compelling, we did not synthesize the toxin de novo, and we were unable to categorically prove that the polar toxins caused mortality or that they were metabolites of an undefined parent compound. However, our approach does provide a template for marine fish kill investigations associated with marine toxins and inherent limitations of existing methods. Our study also highlights the need for more rapid and cost-effective tools to identify new marine toxins, particularly small, highly polar molecules.

“…The industry has also disrupted local ecosystems as juveniles and certain sexes are ISSN 2157-6092 2017 targeted unevenly and can skew entire populations as such the case with the yellow tang (Zebrasoma flavescens) or the Banggai cardinalfish (Pterapogon kauderni). Both species were collected to the point that a significant decline in abundance occurred and management efforts had to be put in place with the Banggai cardinalfish now on the endangered species list (Dee et al 2014, Williams et al 2009, Lunn and Moreau, 2008.…”
