“…Although strong correlations remain in recent studies (e.g. Aburto-Oropeza et al 2008;Carrasquilla-Henao et al 2013;V azquez-Gonz alez et al 2015), the overall outcomes differ by author, fishery and region. Although recent studies have increased the number of predictors included in the models leading to more variable outcomes, little change in the overall effect was observed.…”

Mangroves are among the most productive ecosystems in tropical and subtropical regions. Historically, mangroves are assumed to support artisanal fisheries, leading decision‐makers to protect mangroves based on this premise. However, this relationship remains unclear, despite positive correlations obtained in different geographical regions. Here, we provide the first meta‐analysis of the mangroves–fisheries linkage at a global level. After conducting a systematic review, 23 publications containing 51 studies estimating the mangrove–fishery linkage were obtained. A random effect model was used to estimate the effect size (Pearson's correlation coefficient) of each individual study as well as the overall effect size. We found strong evidence for the mangrove–fishery linkage with an overall effect size of r = 0.72 (95% CI: 0.61–0.81), and substantial heterogeneity was observed (Q = 143.88, df = 50, P < 0.01). The countries where the studies were carried out were the only significant moderator (QM = 26.07, P < 0.01), while fisheries types (i.e. crab, fish, shellfish, prawn and total) and global regions were not good predictors of the relationship. Our results show that mangrove area is a good predictor of fishery catches overall, confirming the importance of conserving such habitats.

“…However, empirically linking habitat loss to changes in abundance of fished species and quantifying resulting changes in fishing yields can be difficult. A large body of research has examined this relationship with respect to mangroves and coastal fisheries, showing that estimates can vary with region and species by orders of magnitude (Aburto‐Oropeza et al., ; Barbier et al., ; Vázquez‐González et al., ). Importantly, ecosystem services provided by coastal habitats are rarely linear, suggesting that stark thresholds may exist in their relationship with fishery value (Barbier et al., ).…”

Interactions and management for the future of marine aquaculture and capture fisheries

et al. 2019

Aquaculture surpassed wild fisheries as the largest supplier of fish for human consumption in 2014 and is expected to supply the majority of seafood for future increases in demand. Marine and coastal aquaculture, collectively referred to as mariculture, currently represents just 36% of aquaculture production but is poised to expand in the decades ahead. One of the most commonly cited concerns regarding this likely expansion is ecological and socioeconomic interactions with wild‐capture fisheries. While attention has largely been drawn to high‐profile negative externalities from fed finfish and crustacean mariculture, not all marine‐based practices are equivalent. Empirical evidence for the different interactions between mariculture and wild fisheries is often sparse. While negative consequences can arise, positive synergies can also occur. By considering mariculture development in the context of fisheries interactions, we suggest that it is possible to minimize conflicts and maximize positive connections between the two sectors. We provide the first comprehensive synthesis of the interactions between mariculture and wild fisheries, characterizing the types of interactions, evaluating available empirical evidence and identifying where management (sector‐specific and cooperative) can play an important role. We highlight potential effects of mariculture on the efficiency, sustainability, and equity of seafood production and identify remaining knowledge gaps.

“…They are not traded, and have no commercial value, thus they cannot be valued using our standard economic methods (Daniel et al, 2012;Milcu et al, 2013;Satterfield et al, 2013;Pert et al, 2015). These observations have led various research teams to develop frameworks and toolkits to more satisfactorily value CES (Berbés-Blázquez, 2011;Chan et al, 2012a;Felipe-Lucia et al, 2014;Baulcomb et al, 2015;Díaz et al, 2015;Ruckelshaus et al, 2015;Vazquez-Gonzalez et al, 2015;Fish et al, 2016). These frameworks invariably combine ecological and economic aspects of ecosystem service valuation with the social aspect, using non-economic methods to determine the CES values to primary stakeholders.…”

Mangrove Ecosystem Service Values and Methodological Approaches to Valuation: Where Do We Stand?

Mangroves, seagrass meadows, and salt marshes, collectively termed "Blue Forests," are counted among the most valuable and productive coastal ecosystems on the planet. A recent literature review of the Blue Forest valuation research identified mangroves as the most frequently analyzed of these ecosystems, yet the literature demonstrates several deficits in terms of geographic location of studies, methods used to value the services, and most notably, a lack of valuation for cultural services. To better understand this, we analyzed the studies dealing specifically with mangroves from the original literature review to quantify what has been valued, where, by which methods, and the variation in the published values. We then use this information to synthesize our current level of knowledge on the type and value of services provided by mangroves, discuss data gaps, and address specifically the collection of data relevant to cultural ecosystem services (CES). Our results shed light on two principle issues affecting the mangrove valuation literature: overuse of benefit transfer in valuing mangrove ecosystem services and a lack of attention paid to the CES that mangroves provide. The mangrove valuation literature is not yet robust, lacking estimates of many ecosystem services, including CES, such as spiritual and aesthetic value. Most published studies focus on a small selection of ecosystem services based on the availability of benefit transfer values and the ability to easily measure values with market prices. Thus, many ecosystem services that cannot be valued monetarily, but that are often equally important to local communities, are ignored. Given the wide range of ecosystem services mangroves provide and the variety of valuation methods that need to be collectively employed, we argue that doing valuation studies well requires a multidisciplinary approach, bringing together anthropologists, social scientists, ecologists and economists. Thoughtfully and thoroughly including the local stakeholders in valuation studies and the resultant policy discussions leads to a more holistic understanding of the services mangroves provide, and viable solutions with an increase in local willingness to act in accordance with those solutions.
