“…In this review, we have taken into all the published references, with the exception of redundant data and gray literature and the Mediterranean Sea. It is important to underline that, despite the peculiarities of the Mediterranean Sea (Lejeusne et al, 2010), the conclusions we draw from the Mediterranean are largely generalizable to the world ocean (e.g., Yokoyama et al, 1997;Boyra et al, 2004;Loya et al, 2004;Hall-Spencer et al, 2006;Weitzman et al, 2019; but see Walls et al, 2017).…”

“…Light available for P. oceanica photosynthesis is also reduced by the high epibiont coating caused by nutrient enrichment (Cancemi et al, 2000(Cancemi et al, , 2003; see below). (ii) Because of the input of fecal pellets and uneaten food, the sediment is enriched in organic matter, which alter its physical and chemical characteristics and enhances anoxic conditions and sulfate reduction processes (Pergent et al, 1999;Cancemi et al, 2003;Holmer et al, 2003Holmer et al, , 2008Weitzman et al, 2019). This factor emerges as one of the main drivers of benthic deterioration, via e.g., sediment anoxia (Holmer et al, 2008).…”

“…The transfer of farmed species from one region to another has not only been a vector for accompanying epibionts ("hitch-hikers"), but also for microbial pathogens and for metazoan parasites (Grigorakis and Rigos, 2011;Weitzman et al, 2019). Usually, it is not in the interests of a pathogen or a parasite to kill its host: if the host dies, they will die too.…”

“…Although none of the participants identified the potential environmental effects of aquaculture (Table 1), these aspects cannot be neglected, and they could be a challenge for CBMA. Both shellfish and seaweed farming could result in benthic organic loading and alteration of water quality properties in the vicinity of the farm (Weitzman et al 2019). In addition, the deployment of infrastructure and additional biomass in the ocean could result in ecosystem effects such as the alteration of the food web, pollution, or the introduction of exotic or invasive species (Weitzman et al 2019).…”

These potential effects depend on the location and size of the farm as well as management practices.…”

Aquaculture is one of the world’s fastest growing food production sectors and presents an opportunity for rural community development that can support coastal livelihoods. An ecosystem approach to aquaculture (EAA) has been recommended to facilitate socially and environmentally sustainable development, yet there remains a need to better involve people in planning and operational aspects. Community-based management may help to implement principles of the EAA; however, context-specific research is needed to understand its potential application and suitability. This research explores opportunities for community-based marine aquaculture (CBMA) for nonfinfish in the context of Nova Scotia, Canada, through a series of stakeholder interviews. Results suggest that all stakeholder groups interviewed were positive about the potential for CBMA to support sustainable aquaculture growth in the province; however, key questions around operationalizing CBMA remain. The aquaculture industry is on a continual path for growth worldwide and, therefore, it becomes increasingly important to proactively examine strategies such as CBMA that can help to facilitate EAA in a way that genuinely puts people at the centre of aquaculture development and governance.

1. Marine protected areas of the Caribbean islands are at high risk of non-native species (NNS) introductions and impacts that may threaten conservation goals. To inform conservation management of these protected areas, the present study identified potentially-invasive NNS as well as introduction vectors and pathways for the southern Caribbean islands of Grenada, and St Vincent and the Grenadines.2. The activities associated with the introduction vectors and pathways relevant to priority NNS were assessed to highlight locations within the risk assessment area at elevated risk of NNS introduction and spread.3. The preliminary NNS list comprised 223 species of which 10 were screened using the Aquatic Species Invasiveness Screening Kit, which generated scores indicating moderate-to-high risk (18-51) of being invasive in the risk assessment area, based on generalized global threshold scores. The ports of Kingston (St Vincent) and St George's (Grenada) were associated with the greatest shipping and boating activity, indicating elevated risk of NNS introductions by way of these vectors.Coastal areas in the south of the risk assessment area were associated with highest risk of introduction of NNS by natural dispersal.4. The evidence presented in this study provides a strong basis upon which to develop and implement risk-based biosecurity and monitoring programmes to protect and conserve this region's marine protected areas.
