Social license to operate (SLO), a concept that describes community acceptance and approval of incoming industry, offers a lens for better understanding these barriers and an opportunity to identify strategies for successful development. Efforts to measure and predict social license have begun, but these efforts primarily focus on company actions and impacts. This study seeks to expand the utility of social license within the aquaculture sector by developing a preliminary quantitative framework that can predict a community’s willingness to issue SLO prior to siting.

There are several ways in which birds interact with shellfish aquaculture. Birds can cause significant damage to crops through predation. Some birds fall into the category of protected resources and farmers have been variously accused of interfering with foraging, (either attracting or disturbing or both) and interfering with hunting. Birds can be attracted to aquaculture structures for roosting or foraging and their guano can impact water quality and trigger the need for growers to develop management plans under the National Shellfish Sanitation Plan.
