“…Over the course of the last years, it became evident that the "social license to operate, " reflecting continuous acceptance, is a central item in the future development of the aquaculture sector (SAPEA, 2017). Indeed, aquaculture offers a variety of socio-economic benefits through the supply of highly nutritious foods and commercially valuable products, providing jobs and creating income, especially in remote areas (FAO, 2012(FAO, , 2014ICES, 2012;Krause et al, 2015). For instance, it could be observed in South Africa that the employment of a large number of unskilled and semi-skilled personnel in the aquaculture sector had a large local socio-economic positive impact in coastal communities with traditionally high-unemployment rates (Troell et al, 2006;Nobre et al, 2010).…”

By moving away from coastal waters and hence reducing pressure on nearshore ecosystems, offshore aquaculture can be seen as a possible step towards the large-scale expansion of marine food production. Integrated multi-trophic aquaculture (IMTA) in nearshore water bodies has received increasing attention and could therefore play a role in the transfer of aquaculture operations to offshore areas. IMTA holds scope for multi-use of offshore areas and can bring environmental benefits from making use of waste products and transforming these into valuable co-products. Furthermore, they may act as alternative marine production systems and provide scope for alternative income options for coastal communities, e.g., by acting as nodes for farm operation and maintenance requirements. This paper summarizes the current state of knowledge on the implications of the exposed nature of offshore and open ocean sites on the biological, technological and socio-economic performance of IMTA. Of particular interest is improving knowledge about resource flows between integrated species in hydrodynamic challenging conditions that characterize offshore waters.

“…Yet, recent innovations in aquaculture production (e.g., in breeding, feed, and management) have not translated into comparable contributions to food and livelihoods at the scale necessary to meet the future demand for fish [39]. This is particularly so in regions such as the Pacific, where aquaculture still represents a fraction of fish production.…”

Social Dynamics Shaping the Diffusion of Sustainable Aquaculture Innovations in the Solomon Islands

et al. 2017

Sustainably feeding the world's growing population represents one of our most significant challenges. Aquaculture is well positioned to make contributions towards this challenge. Yet, the translation of aquaculture production innovations into benefits for rural communities is constrained by a limited understanding of the social dynamics that influence the adoption of new agricultural practices. In this paper, we investigate the factors that shape the spread of small-scale tilapia aquaculture through rural Solomon Islands. Based on diffusion of innovation theory, we focus on three potentially influential factors: (i) socio-economic characteristics of adopters; (ii) the role of opinion leaders; and (iii) characteristics of the innovation. We find that farmers who were wealthier, older, and had more diverse livelihoods were most likely to be adopters. Opinion leaders facilitated the adoption of tilapia aquaculture, but lacked the capacity to provide fundamental knowledge necessary to realize its potential benefits to food security. The paper argues for more explicit attention to the poorest households and makes the case for a deeper engagement with the broader social and institutional contexts that shape the adoption process. Aquaculture interventions that account for these social dynamics are critical for translating production innovations into sustainable benefits to rural communities.

“…Up-to-date research works call the attention also to the importance of knowledge transfer and exchange of experience between field experts and policy makers. The importance of well established and conscious regulations (Krause et al, 2015;Alexander et al, 2015) is emphasized, too.…”

A B S T R A C TFirst implementation and testing of Direct Computer Mapping (DCM) based methodology for modeling and dynamic simulation of Recirculating Aquaculture Systems (RAS) were made and evaluated. The test model of the underlying hybrid, multiscale processes were generated for a simplified example system, utilizing data and empirical equations for the production of African catfish (Clarias gariepinus) from the available literature. The Waste Water Treatment model was temporarily implemented by efficiency factor. The authors studied how the graphically generated, locally programmable building elements can be applied for dynamic simulation of the given complex system. According to these previous test results, DCM methodology can give a flexible and robust solution to describe the backbone structure of a core model that can be adapted to the changing formulation and data in the local models, individually. In addition, DCM methodology seems to be able to generate the various RAS schemes from the model of a single fish tank. Based on the experiences, as well as, with the knowledge of a more comprehensive data and relationships, in the ongoing work we shall implement and analyze complex RAS models.
