Abstract
Abstract Understanding the quality of farmed fish and how the quality can vary and compare to the wild equivalent is central to ensuring aquaculture produced fish and products meet consumer and regulatory requirements. Proximate, fatty acid and mineral composition of farmed and wild yellowtail ( S. lalandi ) was established and compared. No difference in proximate composition (p ≥ 0.05) between the farmed and wild fish was observed, whilst numerous differences were apparent in fatty acid and mineral compositions. The total SFA, MUFA and PUFA were statistically similar (p ≥ 0.05) between the two groups (farmed versus wild); however differences at the subgroup and individual fatty acid levels were apparent. The farmed fish had significantly higher (p Statement of relevance The manuscript has produced novel findings which should be of interest to readers in the food science, aquaculture and fisheries sector as well as consumers. Wild S. lalandi is widely consumed throughout its distribution range, while the aquaculture production of S. lalandi has increased considerably in recent years due to its ever increasing demand. Within South Africa and Namibia yellowtail has been identified as a good candidate species for the growing aquaculture sector; however the quality (sensory, nutritive, shelf life stability etc.) of cultured fish can vary and there is inadequate understanding in how well farmed yellowtail compares to its wild counterpart. Therefore this study, in part, fills this current knowledge gap, providing consumers and aquaculturists with enhanced scientific information and understanding.
