Mean measured proximate content for 144 samples of salmo salar

Data from a survey of nitrogen content in farmed Atlantic Salmon. This is a reduced data set derived from data obtained in a published survey: See Colwell, P., Ellison, S. L. R., Walker, M. J., Elahi, S., Burns, D. T., &amp; Gray, K. (2011). Nitrogen Factors for Atlantic Salmon, Salmo salar, farmed in Scotland and in Norway and for the derived ingredient, “Salmon Frame Mince”, in Fish Products. <em>Journal of the Association of Public Analysts (Online)</em>, <em>39</em>, 44. The data set is reduced by a) restriction to fillet and whole fish (omitting frame mince), b) restriction to nitrogen and fat content c) averaging of duplicate original observations. The reduced data set forms a complete full factorial design on five factors affecting nitrogen content. The data set is in the tab-delimited text file Salmon_N_means_FW.txt; Data field descriptions are provided in Salmon_N_means_FW_fields.txt.
