“…fatty part of fillet or heads (personal communication). Fish frames (i.e., the residual head and bones that remain after filleting) are commonly also used as baits in crustacean fisheries, in creels (cages) typically used for this purpose (Murray, 2015). Whilst it can be verified that such frames are derived from disease-free farms if sourced locally (and therefore unlikely to pose a disease hazard), this may not be the case for frames from imported fish and therefore a precautionary approach could entail the removal of the head from the frame before using it as a bait for these fish (Murray, 2015).…”

“…Frames, a by-product of salmon processing, were considered as potential vector of hazards to Scottish salmon farms when used as baits for catching crabs (creel) in the vicinity of these farms (Murray, 2015). Hazards included a range of viral, bacterial and parasitic species.…”

“…Whilst in general, risks were considered low or absent, an issue might be the production of frames by secondary processors with infection by diseases for which there is no obligatory notification procedure. In addition, massive imports from other countries where diseases occur may also contribute to enhanced risk based on their volumes (Murray, 2015).…”

“…Baits from salmon by-products that are used in the vicinity of salmon farms can be a source of biohazards to the salmon in these farms, for example if the by-products used have become infested with parasites. In a modelling study, (Murray, 2015) simulated an alternative route of infection for farmed salmon by a range of pathogens. Risk pathways were construed for the scenario that infected salmon were to be processed and a particular by-product, frames, were to be released as baits for creel or lobster by fishermen in the marine environment close to salmon farms.…”

The objective of Aquarius project was to test the applicability of a food chain analysis on Atlantic salmon farmed in Norway to identify and monitor vulnerabilities and drivers of change for the identification of emerging risks. To this end, a comprehensive literature review was conducted complemented with expert views collected by on‐line questionnaires and in‐depth interviews. This review provided an overview of the various stages in the supply chain from farm to consumer and the identification of i) existing and emerging human and animal health hazards, ii) vulnerabilities, iii) control measures, iv) drivers of change, and v) related indicators. Next step in the study was to i) complement the list of vulnerabilities followed by a prioritisation using focus group discussions and Failure Mode and Effect Analysis (FMEA) method and ii) link drivers of change acting upon the (prioritised) vulnerabilities and identification of associated indicators and data sources by means of a Delphi method. Based on the experiences obtained with the different methodologies during this project, the Aquarius team considers literature review, and a direct face‐to‐face interaction with experts (in‐depth interviews, focus group discussions and FMEA in a workshop setting) as being most effective regarding output and effort. The comprehensive information collected formed the basis for the methodology to baseline key indicators of the selected vulnerabilities. The methodology proposed comprised a Bayesian Network (BN) that links data sources for indicators and drivers of change to the prioritised vulnerabilities and was demonstrated for salmon health. A Decision Support System (DSS) with such BN integrated was designed. The current BN and DSS could flag an increased exposure of known hazards that may occur due to changes in indicators but new hazards are not identified. The proposed methodology could be used instead to show trends in vulnerabilities, indicators, increased exposure of known hazards and for scenario studies.
