Abstract
The expansion of low-trophic aquaculture (shellfish and sea plants) is limited in many regions by a fragmented regulatory process that is difficult for smallholder farmers to navigate. Small-scale Aquaculture Development Areas (ADAs) can remove some of this regulatory burden by establishing pre-approved zones for aquaculture development; however, an understanding of local support for low-trophic aquaculture is needed to understand the potential of ADAs. A survey was used to solicit information about community support for shellfish and sea plant aquaculture in Pictou County, a coastal area of Nova Scotia, Canada. Participants had a positive impression of low-trophic aquaculture, but residents in one coastal area reported greater perceived negative impacts on the recreational use and enjoyment of coastal areas and views, while residents in another coastal area reported a higher level of support for shellfish aquaculture. In general, participants also valued community involvement in aquaculture management, local ownership of farms, and community benefits from the presence of farms. Results suggest that top-down communication is unlikely to play a significant role in acceptability. Instead, experience of low trophic aquaculture and place-based values are important for understanding social acceptability. Community involvement in the development of ADAs and the distribution of benefits from farming could support trust in ADAs and social licence for low-trophic aquaculture.
