Overall Chemical Composition Of Dogfish (Squalus Acanthias L.) (Komposisi Kimia Keseluruhan Daging Ikan Cucut Botol (Squalus Acanfhias L.)

Abstract

The chemical composition of dogfish was determined for a number of fish between April 1991 and May 1993. The chemical composition of fish largely influenced by species. sex; slage of maturation, season of capture, size, and the feeding habits of the fish. Three other factors which also affect the chemical composition are method of sample preparation (i.c. which part of the fish is taken, and the homogeneity of the sample), the method of analysis, and the freshness of fish. The mean values for proximate composition of fresh dogfish were 20.7 % crude protein (12.5 % net protein), 5.20 % lipid, and 1.2 % ash, while the moisture content was 74.58 %.
