The activity of myofibrillar ATPase declined with length in the five species examined ( Merlanogrummus aeglefinis L., Merrluccius merluccius L., Physis blennoides Brunnich, Pleuronectes platessa L. and Merlangius merlangus L.). This decline was related to a decrease in the in vitro muscle contraction rate and appeared to be a scale rather than an age effect. Actomyosin was extracted from Merlangius merlangus L. to investigate the length related changes in the myofibrillar protein.
