“…This was also seen in the majority of species where it was observed that slow-red muscle occurs as a continuous mid-lateral strip, the relative dimension of which increases in rostro-caudal direction, achieving maximal values in the posterior part of the body (Bone, 1978). The finding that most of the red muscle is in the posterior part of Pagellus bogaraveo further supports the idea that most power for steady swimming at moderate speeds comes from posterior rather than anterior musculature (Luther et al, 1995). As Pagellus bogaraveo is a benthopelagic fish (Bauchot and Hureau, 1990), this result also suggests that the possession of a relatively high proportion of slow-red muscle is not confined to active, pelagic fish (Luther et al, 1995).…”

In general, the rostral myomeres showed more advanced and organized developmental stages than the caudal ones at early ages, following the rostro-caudal myogenesis rule of most fish (Johnston et al, 1996).…”

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.

“…4C). This contrasts not only with normal red (slow) fibre sarcomeres but also with those of white (fast) and intermediate fibres, all of which have their T-tubules located at the Z-lines (Luther et al 1995;Stoiber 1991Stoiber , 1996.…”

“…Teleost myotomes are composed almost entirely of twitch fibres that commonly comprise slow contracting 'red' fibres laterally next to the horizontal septum as well as fast contracting 'white' fibres that, together with a minor population of intermediate fibres, constitute the rest of the myotome (Rome et al 1988;Luther et al 1995). However, in some teleost species small populations of other muscle fibres have been detected that are assumed to exhibit tonic characters, but the true nature and function of these fibres has not been fully elucidated.…”

Tonic fibres in axial muscle of cyprinid fish larvae: their definition, possible origins and functional importance

Teleost fish are known to develop small populations of muscle fibres that are assumed to be tonic in nature although their contractile properties and many other characteristics remain unknown. Here we attempt to resolve some of the ambiguity and confusions surrounding the definition and functional role of tonic fibres in teleosts and provide new information on their ontogeny. We investigate the differentiation of tonic muscle fibres in three species of cyprinid fish using electron microscopy, histochemistry, immunohistochemistry and in situ hybridization. The fine structure of the fibres defined as tonic in the larvae used in this study complies with patterns known from studies in teleost adults. This allows formal definition of tonic fibres in cyprinid larvae. The tonic fibres may be recognized by a variety of features: (1) by their characteristic position along the medial confines of the red muscle insertion at the horizontal septum, (2) their fine structure, including solid clusters of irregularly cleaved myofibrils, thick and wavy Z-lines, and T-tubules at the A-band/I-band transitions, (3) their histochemical features, specifically weak but obvious staining for mATPase after alkaline preincubation, and lack of SDH activity in the more advanced larval stages, (4) their unique immunological properties, being the only fibre type in the myotome that reacts with a serum against chicken tonic myosin (anti- T2). Expression of tonic characters usually begins within a few fibres in the dorsal domain of the superficial red muscle insertion at the horizontal septum and hence involves a high degree of dorso-ventral polarity. The present evidence indicates that tonic fibres arise from separate myogenic stem cells rather than by transdifferentiation from existing red fibres. First appearance of tonic fibres during ontogeny correlates closely with the onset of free swimming and exogeneous feeding. We use this fact to argue that tonic fibres are probably a prerequisite for efficient locomotory control during prey capture, shoaling and predator avoidance.

“…Triads, consisting of the transverse or t-tubule and two surrounding sarcoplasmic cisternae are usually found at the Z-line in fishes with white fibers (Akster 1981;Luther et al 1995). Triads are also found at the Z-line in sonic muscles in weakfish Cynoscion regalis (Ono and Poss 1982), tigerfish Terapon jarbua (Eichelberg 1976), catfishes Pimelodus and Platydoras (Ladich 2001) and the butterflyfish Hemitaurichthys polylepis ).…”

Fishes have evolved multiple mechanisms for sound production, many of which utilize sonic muscles that vibrate the swimbladder or the rubbing of bony elements. Sonic muscles are among the fastest muscles in vertebrates and typically drive the swimbladder to produce one sound cycle per contraction. These muscles may be extrinsic, typically extending from the head to the swimbladder, or intrinsic, likely a more-derived condition, in which muscles attach exclusively to the bladder wall. Recently discovered in Ophidiiform fishes, slow muscles stretch the swimbladder and associated tendons, allowing sound production by rebound (cock and release). In glaucosomatids, fast muscles produce a weak sound followed by a louder one, again produced by rebound, which may reflect an intermediate in the evolution of slow to superfast sonic muscles. Historically, the swimbladder has been modeled as an underwater resonant bubble. We provide evidence for an alternative hypothesis, namely that bladder sounds are driven as a forced rather than a resonant response, thus accounting for broad tuning, rapid damping, and directionality of fish sounds. Cases of sounds that damp slowly, an indication of resonance, are associated with tendons or bones that continue to vibrate and hence drive multiple cycles of swimbladder sound. Stridulation sounds, best studied in catfishes and damselfishes, are produced, respectively, as a series of quick jerks causing rubbing of a ribbed process against a rough surface or rapid jaw closing mediated by a specialized tendon. A cladogram of sonic fishes suggests that fish sound production has arisen independently multiple times.
