Theuerkauf, SJ, Barrett, LT, Alleway, HK, Costa-Pierce, BA, St. Gelais, A, Jones, RC. Habitat value of bivalve shellfish and seaweed aquaculture for fish and invertebrates: Pathways, synthesis and next steps. Rev Aquac. 2021; 00: 1– 19. https://doi.org/10.1111/raq.12584
- Provides literature review, but no original research. Reviews 65 studies of nekton at aquaculture sites.
- Co-author Robert Jones is director of the global aquaculture alliance.
- Acknowledges a spectrum of aquaculture practices, with positive, neutral, or negative effects on ecosystems.
- Reviews literature and finds higher levels of nekton abundance and biodiversity in seaweed and bivalve aquaculture installation.
- Aquaculture can have negative effects of shorebird foraging, and increase disease spread, and impacts to SAV particularly as scale and intensity increase.
- Identifies five factors influencing aquaculture effects:
- Local environmental conditions
- Intensity and scale of culture
- Cultivation gear utilized
- Species cultivated
- Farm management practices
- The review focuses on ways that suspended and surface bivalve culture can maximize ecosystem services, with a focus on positive effects of structure.
