The distribution of connective tissue content in swimming muscle of cod (Gadus morbua)

Summary The amount and distribution of connective tissue in the swimming muscle of cod (Gadus morhua) have been determined. By biochemical analysis, the collagen was found to make up 1,5 % of the total protein content. Measured by light microscopical morphometric analysis, the areal fraction of the connective tissue elements was found to be 3,0 % of the total muscle area. The areal fraction of myocommatal connective tissue mentioned above was found to be 2.3 %. The thickness of the endomysial sheath was calculated by morphometry based on electron microscopy, and was found to be 0.30 and 0.16 μ for red and white fibres, respectively. The areal fraction of the endomysial sheaths was 2.3 % in red muscle and 0.5% in white muscle. The endomysial sheaths make up 25% of the total connective tissue in the swimming muscles. These sheaths influence the binding properties of fish muscle products.
