  abstract = {{L}imited information is available on mineral content of {S}outh {A}frican aquatic organisms. {T}he aim of the study was to determine mineral content of {S}outh {A}frican marine species, either farmed or identified as candidate aquaculture species, and their by-products (muscle tissue, head, frame or viscera) to estimate their potential contribution to {R}ecommended {N}utrient {I}ntakes and identify nutritional and functional components for potential  product development for human consumption and/or for animal feeds. {T}he species analysed included fishes ({P}omadasys commersonnii, sea-grown {O}ncorhynchus mykiss, {S}eriola lalandi, {A}rgyrosomus japonicus), molluscs ({H}aliotis midae) and seaweeds ({L}aminaria pallida, {E}cklonia maxima, {M}acrocystis pyrifera, {U}lva lacinulata, {G}racilaria gracilis). {F}reeze-dried, composite samples (n=3 per specimen) were analysed by {ICP} {AES} and {ICP}-{MS} for mineral content. {F}or trace elements (expressed as mean±{SD} mg/100g dw), iron ({F}e) levels in fish fillets of {A}. japonicus (13.2±3.1) were 3-4-fold higher (p<0.05) compared to other species. {O}. mykiss (3.2±0.9), {S}. lalandi (2.7±0.4) and {A}. japonicus (3.2±0.3) fillets displayed similar zinc ({Z}n) levels. {C}alcium and phosphorus levels were similar among fish fillets. {F}or by-products, viscera of {S}. lalandi and {O}. mykiss contained the highest (p<0.05) levels of {F}e (30.2±2.8) and {Z}n (35.7±16.6). {A}mong seaweeds, {U}. lacinulata displayed significantly higher (p<0.05) amounts of {F}e and aluminium ({A}l) ({F}e 23.4±2.0; {A}l 19.3±2.4), followed by {G}. gracilis ({F}e 16.0±1.3; {A}l 11.4±0.9). {T}hese results highlight the importance of assessing the nutritional value and potential harmful elements of different species and the potential of selecting nutrient-rich species to maximise nutritional outcomes of aquaculture and of using by-products to develop innovative food products.},
