SUMMARYFisheries stocks are rapidly declining around the world. A reduction in the consumption of unsustainable seafood may help curb this decline. Sustainable seafood consumption is not commonplace, even in the marine science and conservation community. The frequency of unsustainable and/or unlabelled seafood at marine science and conservation meetings motivates this enquiry and call for leadership. Information about the species served and where they were caught/farmed was obtained for seven marine ecology and conservation meetings held in Australia, attended by c. 4000 people from around the world. Menu item sustainability was assessed according to the relevant sustainable seafood guide, which considered stock status and impact of fishing/aquaculture method. Seafood was served at all meetings; four meetings served at least one unsustainable species, and only two meetings served a sustainable species. Additional leadership by marine scientists, especially conservationists, is urgently required to turn science into action and ensure that sustainable seafood is available, not only at meetings, but more widely, to achieve a positive conservation outcome.

Abstract Frid, C. L. J., and Paramor, O. A. L. 2012. Feeding the world: what role for fisheries? – ICES Journal of Marine Science, 69: 145–150. Fisheries (wild capture and aquaculture) deliver more than 110 million tonnes of food and around 15% of the dietary protein to the 7 billion people currently living on the planet. With the global population expected to peak at 9 billion by 2050, and >80% of global fish stocks currently fully or overexploited (and aquaculture is at least in part dependent on capture fisheries), the contribution of fisheries looks set to decline. The challenge is therefore determining how better management, an ecosystem perspective, and more efficient utilization of fisheries waste can support fisheries products continuing to contribute significantly to “feeding the world” up to and beyond the population peak.

AbstractXavier, J. C., Phillips, R. A., and Cherel, Y. 2011. Cephalopods in marine predator diet assessments: why identifying upper and lower beaks is important. – ICES Journal of Marine Science, 68: 1857–1864. Cephalopods are components of the diet of many predators worldwide. They are identified mainly using their chitinized upper and lower beaks, but because it has been assumed that the number of upper and lower beaks would be the same in predator diet samples, more effort has been put into creating keys for the lower beaks, which are more easily identifiable from morphology. A test is made of whether the number of upper and lower beaks differs in diet samples collected from a major cephalopod predator, the wandering albatross (Diomedea exulans), potential biases in the estimation of predator diets are assessed, and upper:lower beak ratios in published studies of other seabirds, seals, whales, and fish from different parts of the world reviewed. The ratio of upper to lower beaks in diet samples from wandering albatrosses varied greatly in a single year (from 69.6% more lower beaks to 59% more upper beaks), and between years (from 0.5 to 32.1% more upper beaks), and biases were greater for certain cephalopod species, resulting in underestimation of their relative importance. Future studies need to consider using both upper and lower beaks to improve the assessment of the contribution of different cephalopods to predator diets.

Many fisheries in the world are data-moderate, with data types (e.g., total removals, abundance indices, and biological composition data) of varied quality (e.g., limited time series or representative samples) or available data. Integrated stock assessments are useful tools for data-moderate fisheries as they can include all available information, can be updated due to the availability of more information over time, and can directly test the inclusion and exclusion of specific data types. This study uses the simulation testing and systematic data reduction from the US West Coast benchmark assessments to examine the performance of Stock Synthesis with catch and length (SS-CL) compositions only. The simulation testing of various life histories, recruitment variabilities, and data availability scenarios found that the correctly specified SS-CL can estimate unbiased key population quantities such as stock status with as little as 1 year of length data although 5 years or more may be more reliable. The error in key population quantities is decreased with an increase in years and the sample size of length data. The removal of the length compositions from benchmark assessments often caused large model deviations in the outputs compared to the removal of other data sources, indicating the importance of length data in integrated models. Models with catch and length data, excluding abundance indices and age composition, generally provided informative estimates of the stock status relative to the reference model, with most data scenarios falling within the CIs of the reference model. The results of simulation analysis and systematic data reduction indicated that SS-CL is potentially viable for data-moderate assessments in the USA, thus reducing precautionary buffers on catch limits for many stocks previously assessed in a lower tier using catch-only models. SS-CL could also be applied to many stocks around the world, maximizing the use of data available via the well tested, multifeature benefits of SS.

Sustainable Behavior

Achieving a sustainable future will require that people do things differently. Community-based social marketing (CBSM) provides a framework for fostering sustainable behavior, and the approach is being increasingly utilized across a range of domains including energy conservation, recycling, reducing water consumption, promoting sustainable seafood consumption, and many others. This article provides guidance to practitioners about the optimal use of specific behavior change tools. The article summarizes commitment strategies, social diffusion, goal setting, social norms, prompts, incentives, feedback, and convenience as effective tools for encouraging changes in behavior. For each, we summarize the basic approach and provide recommendations regarding when each tool is most appropriate, depending on the existing levels of barriers and benefits associated with the target behavior. The article concludes with three examples of CBSM to illustrate this selection process.

Sustainably feeding a growing human population is one of the greatest food system challenges of the 21st century. Seafood plays a vital role in supporting human wellbeing, by providing bioavailable and nutrient-dense animal-source food. In Thailand, seafood demand is increasing, and wild capture fishery yields have plateaued, due to oceanic ecosystem degradation and fishery stock exploitation. In this study, we investigated the supply trend of fishery products and subsequent seafood-derived nutrient availability over the last decade. In addition, we explored the possibility of predicting seafood availability and consumption levels, including adherence to Thailand’s national food guide and global dietary recommendations for sustainable seafood consumption. Our findings indicate that, at national-level, fishery products supplied between 19% and 35% of the Thai populations recommended dietary protein intake, 4–6% of calcium, 6–11% of iron, and 2–4% of zinc from 1995 to 2015. Nevertheless, our research also reports that if Thailand’s wild-caught seafood production were to decrease by 13%, as is highly likely, by 2030, the country might face a per capita supply deficit of fish and shellfish to meet healthy and sustainable dietary recommendations (28–30 g/day), let alone the current Thai average intake (32 g/day). Although a 1% per year increase in aquaculture production might bridge this supply gap, policymakers and relevant fishery stakeholders must consider the long-term environmental impacts of such an approach in Thailand.
