Gives general information on the uses that can be made of compositional data, sampling of the material for analysis, preparation of a sample, and the accuracy of analysis. Explains the meaning of proximate analysis, and describes the basic methods used specifically for fish at Torry Research Station to measure the main classes of substances present in fish and fish products, water, proteins, fat, minerals and carbohydrate. All the methods are given in sufficient detail to be used by a trained analyst. More recent information on the measured nitrogen content of British commercial fish species can be found in: McLay et al. (1986). J. Assoc. Publ. Analysts, Vol. 24, 131-139.
