“…It differs from the skeletal muscle of other vertebrates in its segmental antero-posterior myotomal organization and by the fact that the two main types of fibres (fast and slow) are not intermingled but develop in physically distinct areas. The superficial red-slow fibres are responsible for slow swimming or cruising, whereas the bulk of deep white-fast fibres are used in fast burst locomotion (Johnston et al 1977;Bone 1978). Another type of fibre, the so-called intermediate fibre, also occurs in most fish (Johnston et al 1977).…”

Also, fish muscle growth differs from that of mammals or birds as new fibres are continuously produced over much of the life cycle (Rowlerson and Veggetti 2001).…”

Previous studies on the histochemistry and immunoreactivity of fibres in lateral muscle of blackspot seabream indicated that there is a developmental transition in the composition of myofibrillar proteins, which presumably reflects changes in contractile function as the fish grows. We hypothesize that the phenomenon underscores age and spatial differences in the expression of myosin light chains (MLC), not studied yet in this species. In this study, we examined selected stages in the post-hatching development of the muscle of blackspot seabream: hatching (0 days), mouth opening (5 days), weaning (40 days) and juveniles (70 days). The spatial expression of embryonic MLC 1 (MLC1), 2 (MLC2) and 3 (MLC3) was studied by in situ hybridization. Overall, MLC expression patterns were overlapping and restricted to the fast muscle. At hatching and mouth opening, all MLC types were highly expressed throughout the musculature in fast muscle. The expression levels in fast muscle remained high until weaning when germinal zones appeared on the dorsal and ventral areas. The germinal zones were characterized by small-diameter fast fibres with high levels of MLC expression. This pattern persisted up to day 70, when the germinal zones disappeared and expression of MLCs was observed only in the smaller cells of the fast muscle mosaic. These results support our hypothesis and, together with previous imunoand histochemistry results, allow a better understanding of the mechanism of muscle differentiation and growth in fish beyond larval stages, and form-the basis for further comparative and experimental studies with this economically relevant species.

“…The myotomal muscle of teleosts contains two main fibre types, grouped in two layers: (1) subdermal red muscle, with oxidative metabolism and slow contraction, and (2) deep white muscle, with glycolytic metabolism and fast contraction (Johnston et al 1975(Johnston et al , 1977Bone 1978). Between those layers, an intermediate zone is found, with fibres characterised by being essentially fast contracting, with both intermediate resistances to fatigue and shortening speed (Johnston et al 1977).…”

Muscle cellularity was studied in Pagellus bogaraveo juveniles fed on diets with different protein contents. Measured in transversal body sections, at both post-opercular and post-anal locations, the morphometric variables estimated were: total muscle area (A), total number of fibres (N), number of fibres per unit area of muscle (N A ) and cross-sectional fibre area ð" aÞ; of the two main muscle fibre types. At the end of the experiment fish fed on diets having more than 40% of protein displayed significantly higher body weight. Fish fed on protein-rich diets exhibited greater " a and N. For fish fed on 30 and 50% protein diets the morphometric parameters measured grew linearly with the fish weight. High-protein diets favoured muscle hyperplasia. When comparing rostral and caudal locations, a greater N and a smaller " a of posterior red fibres were the consistent differences found-a fact, to our knowledge, so far unreported for fish.

“…In contrast to mammalian muscle, which is characterised by a mixture of fibre types, the axial muscle of teleosts shows anatomically separate zones of muscle fibre types. The muscle fibres are separated in two layers: superficial slow-red muscle, with oxidative metabolism and slow contraction; and deep fast-white muscle, with glycolytic metabolism and fast contraction (Johnston et al, 1977;Bone, 1978 (Johnston et al, 1977).…”

The aim of this work was to gain insights into the mechanism of muscle differentiation and growth in Pagellus bogaraveo, by studying muscle fibre phenotypes identified by immunohistochemistry. At hatching, several layers of deep fast-white fibres were covered by a superficial fibre monolayer. At 5 days, slow-red fibres appeared near the lateral line nerve. At 40 days, the intermediate-pink muscle became visible, and in the slow-red and fast-white muscle layers transitions from larval myosin isoforms to the isoforms typical of adult muscle occurred. Between 70 and 100 days, small fibres with a distinct ATPase profile appeared throughout the fast-white muscle, marking the onset of "mosaic" hyperplasia. The myosin of the original superficial monolayer fibres underwent two myosin transformations, before being slowly replaced by an adult slow-red isoform. In juveniles and adults, the slow-red muscle layer could be resolved into two distinct types. The analysis of fibre phenotypes indicated that post-larval muscle growth occurred by two distinct stages of hyperplasia. This study offers a basis for further comparative and experimental studies with this economically relevant species, namely for identifying factors influencing its muscle growth dynamics and disclosing underlying mechanisms.
