“…They represent a small-diameter fibre population (therefore also referred to as small-diameter fibres) with a species-specific location next to the red fibres. To date, they have been described in the stone loach Barbatula barbatula (L.) (Kilarski & Kozlowska, 1985), the pike Esox lucius L. (Zawadowska & Kilarski, 1984), a series of cyprinids (Sänger et al, 1988(Sänger et al, , 1989Kilarski, 1990) and the pond loach Misgurnus fossilis L. (Karasinski et al, 1994).…”

The morphology and the effect of an endurance training programme on tonic muscle fibres were studied in chub Leuciscus cephalus, by means of histochemistry and immunohistochemistry, electronmicroscopy and morphometry/stereology. Location and distribution, SDH-and mATPase-activity, reaction to an anti-tonic myosin antibody and ultrastructural features of the fibre type were investigated. With regard to training conditions, fibre size was not significantly affected. However, an increase in the volume densities of mitochondria, lipid and myofibrils can be observed, suggesting a training influence on the aerobic capacity of the so-called tonic muscle fibres. Based on the quantitative findings, the fine structure and the response to training, similarities with intermediate muscle fibres and the functional role of these so-called tonic muscle fibres are discussed. 1997 The Fisheries Society of the British Isles

“…ATPase activity is moderate to low and of varied stability against alkaline and acid preincubation; staining for SDH activity is negative (Kilarski andKozlowska 1985, 1987;Kilarski 1990;Sänger 1993a). Electrophoresis data obtained from the pond loach, Misgurnus fossilis, suggest the 'tonic-type' fibres contain a unique myosin heavy chain isoform (Karasinski et al 1994). This is supported by immunocytochemical evidence from cyprinid fish, where the fibres have been shown to react with an antiserum against chicken-derived tonic myosin (Sänger 1997), which is also able to detect amphibian tonic fibres (Rowlerson and Spurway 1988).…”

“…This pattern also seems to be evident among perciform marine teleosts, as documented for the carangids Decapterus ronchus (not adequately designated; Ramirez Zarzoza et al 1991) and Seriola dumerilii and the sparid Sarpa salpa (designated as 'rosette' fibres, suspected to be 'tonic-type'; Ibabe Martinez et al 2000). The latter (scattered) arrangement occurs in the pike, Esox lucius (Zawadowska and Kilarski 1984), the pond loach, Misgurnus fossilis (Karasinski et al 1994), and the little sole, Solea lutea (Carpenè et al 1982).…”

“…The conjecture that tonic fibres may "maintain the tonicity of the fish's relaxed muscle system" (Kilarski and Kozlowska 1987) appears to be supported by electrophoretic evidence that pond loach (Misgurnus fossilis) tonic fibres possess a distinct myosin heavy chain that gives rise to unique contractile properties (Karasinski et al 1994). Conversely, Sänger (1997) rejects a such postural role on the basis of histochemical and morphometric findings in the chub (L. cephalus).…”

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

et al. 2002

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.

The zebrafish myotome contains tonic muscle fibers: Morphological characterization and time course of formation

It is long known that the skeletal muscle of teleost fish contains muscle fibers which are in all probability of a tonic type according to morphological criteria. However, the evidence for the existence of teleost tonic fibers is still confined to a very small number of species, and knowledge concerning their ontogeny and possible functions is even more restricted. A remarkable deficit in this context is that it is not even exactly known whether the zebrafish, which is widely used to study vertebrate developmental biology, has such fibers, or how they arise. The present study demonstrates the existence of tonic fibers in the zebrafish myotome. They are identical with a fiber population previously termed "red muscle rim" fibers. A combined histochemical, immunocytochemical, and ultrastructural approach is used to characterize the morphology and development of these fibers. This study provides a basis for using the zebrafish model system in the future research on the developmental regulation and the functions of tonic fibers.
