Over the span of a decade, genetic identification methods have progressively exposed the inadequacies of the seafood supply chain, revealing previously unrecognized levels of seafood fraud, raising awareness among the public, and serving as a warning to industry that malpractice will be detected. Here we present the outcome of the latest and largest multi‐species, transnational survey of fish labeling accuracy to date, which demonstrates an apparent sudden reduction of seafood mislabeling in Europe. We argue that recent efforts in legislation, governance, and outreach have had a positive impact on industry regulation. Coordinated, technology‐based, policy‐oriented actions can play a pivotal role in shaping a transparent, sustainable global seafood market and in bolstering healthier oceans.

Abstract:The demand for seafood products on the global market is rising, particularly in Asia, as affluence and appreciation of the health benefits of seafood increase. This is coupled with a capture fishery that, at best, is set for stagnation and, at worst, significant collapse. Global aquaculture is the fastest growing sector of the food industry and currently accounts for approximately 45.6% of the world's fish consumption. However, the rapid development of extensive and semi-extensive systems, particularly intensive marine-fed aquaculture, has resulted in worldwide concern about the potential environmental, economic, and social impacts of such systems. In recent years, there has been a significant amount of research conducted on the development of sustainable saltwater-based food production systems through mechanical (e.g., recirculatory aquaculture (RAS) systems) methods and ecosystem-based approaches (e.g., integrated multi-trophic aquaculture (IMTA)). This review article will examine the potential negative impacts of monocultural saltwater aquaculture operations and review established (RAS) and novel (IMTA; constructed wetlands; saltwater aquaponics) saltwater-based food production systems and discuss their (potential) contribution to the development of sustainable and environmentally-friendly systems.

Abstract-Aquaculture contributed 23.8 million tonnes of aquatic algae globally in 2012. Increasing consumption of seaweed (as food, for the production of hydro-colloids, and for production of third generation biofuels) will lead to an upward trend in its production and cultivation. Aquaculture contributed 66.6 million tonnes of fish in 2012, 42 % of global production. Fish demand globally is rising to meet food and nutritional requirements; aquaculture for fish will grow. However fish farms are marred by criticism of pollution caused by discharge of waste. Integrated multi-trophic aquaculture can reduce pollution through co-culture of several species such as seaweed and mussels that utilise waste disposed from fish farms for their growth and development.A model is investigated which would provide 1.25% of energy in transport in the EU from seaweed. This would involve annual production of 168Mt of seaweed (in excess of present world harvest) integrated with 13Mt of farmed salmon. Themodel proposes 2603 anaerobic digesters, each treating 64,500 t/a of Saccharinalatissima in coastal digesters adjacent to natural gas infrastructure for downstream use in natural gas vehicles.
