A noticeable reduction in weight of the immobilized fish, accompanied by a decrease in the diameter of its myotomal muscle fibres was observed. An overall decrease in the levels of succinate dehydrogenase, phosphorylase and myofibrillar adenosine triphosphatase (m-ATPase) and the lipids was noted histochemically. Metabolic dedifferentiation resulted, obliterating the distinction of various fibre types in myotomal muscle of the immobilized fishes. The present study therefore suggests that disuse may be an important factor in fish muscle also, leading to atrophy.
