“…However, neither Atlantic salmon nor Pacific oyster are native to British Columbia, and both species have had deleterious effects on native species 46 , 47 . Farmed outside their native ranges, algae species can also become invasive, as evidenced by the introduction and rapid spread of Japanese kelp in China 48 . The ecological and socio-ecological consequences of Japanese kelp outside its native range remain unclear, but the potential impacts of invasive algal species are well-documented 49 .…”

Aquaculture has the potential to support a sustainable and equitable food system in line with the United Nations Sustainable Development Goals (SDG) on food security, climate change, and biodiversity (FCB). Biological diversity amongst aquaculture organisms can drive diverse contributions to such goals. Existing studies have assessed the performance of a limited number of taxa in the general context of improving aquaculture production, but few explicitly consider the biological attributes of farmed aquatic taxa at the FCB nexus. Through a systematic literature review, we identify key traits associated with FCB and evaluate the potential of aquaculture to contribute to FCB goals using a fuzzy logic model. The majority of identified traits are associated with food security, and two-thirds of traits linked with food security are also associated with climate change or biodiversity, revealing potential co-benefits of optimizing a single trait. Correlations between FCB indices further suggest that challenges and opportunities in aquaculture are intertwined across FCB goals, but low mean FCB scores suggest that the focus of aquaculture research and development on food production is insufficient to address food security, much less climate or biodiversity issues. As expected, production-maximizing traits (absolute fecundity, the von Bertalanffy growth function coefficient K, macronutrient density, maximum size, and trophic level as a proxy for feed efficiency) highly influence a species’ FCB potential, but so do species preferences for environmental conditions (tolerance to phosphates, nitrates, and pH levels, as well as latitudinal and geographic ranges). Many highly farmed species that are typically associated with food security, especially finfish, score poorly for food, climate, and biodiversity potential. Algae and mollusc species tend to perform well across FCB indices, revealing the importance of non-fish species in achieving FCB goals and potential synergies in integrated multi-trophic aquaculture systems. Overall, this study provides decision-makers with a biologically informed assessment of desirable aquaculture traits and species while illuminating possible strategies to increase support for FCB goals. Our findings can be used as a foundation for studying the socio-economic opportunities and barriers for aquaculture transitions to develop equitable pathways toward FCB-positive aquaculture across nuanced regional contexts.

“…The deposition of excess organic matter may lead to sea floor communities becoming organically enriched to an extent that creates local anaerobic conditions, stimulates toxic microbial releases of hydrogen sulfide and decreases species abundance and biodiversity. Given that kelp farms provide substrate (physical structures) and hideaways for a wide variety of species (Theuerkauf et al 2022), they could potentially support the spread of alien and unwanted species, genetic material and diseases in coastal environments as has been reported recently in the south-eastern Pacific coast (Camus et al 2022).…”

Into the Blue: Securing a Sustainable Future for Kelp Forests global synthesis report is the most comprehensive knowledge review on kelp to date, revealing the state of science on the world’s kelp forests and providing recommended actions to build the recovery of the world’s kelp forests. Aiming to improve our understanding of the value of kelp forests and provide recommendations to protect and sustainably manage them, the report also provides a range of policy and management interventions and options that can be used to maintain these remarkable ecosystems into the future and to support the people and economies that have depended on them for generations. Despite the many challenges they face, kelp forests provide valuable ecosystem services, including supporting coastal fisheries, mitigating climate change, and protecting biodiversity. The report emphasizes the importance of combining sociocultural knowledge with economic valuations to strengthen the case for devoting resources to the conservation, sustainable management, and restoration of kelp, the most extensive marine vegetated ecosystem in the world.
