A final point is that in laboratory studies reducing lipid content of rainbow trout by starvation did not increase whole body PCB elimination (24). Instead PCB concentration in body fat increased as the absolute amount of fat in the fish decreased (24). The latter has also been shown in coho salmon (33). Thus, reducing body fat by starvation does not appear to be a very effective way of increasing PCB elimination in fatty fish.

Short-term starvation in rainbow trout results in a reduction in the rates of synthesis of the whole muscles and the individual fractions and a decrease in the cytochrome oxidase activity (unpubl. results). In a similar manner, rates of synthesis of mammalian myofibrils have been found to be markedly sensitive to nutrition (Bates and Millward 1983). There have been a number of papers which have shown a correlation between the nutritional state of fish and the levels of glycolytic and oxidative enzymes (Sullivan and Somero 1983 Goolish and Adel-man 1987) and it will be of interest to correlate plane of nutrition, whole muscle and mitochondrial protein synthesis and enzyme activities. The correlation between RN A concentration and protein synthesis rates discussed below suggests that we are witnessing a number of nutritionally controlled parameters which are operating in concert increasing, for example, the aerobic scope of the tissues and their scope for protein synthesis.
