The debate about the pattern of muscle formation in teleost fish has recently been heightened in the literature. Here we examine superficial muscle development in the pearlfish, a cyprinid endemic to a small area of Central Europe, and uninfluenced by economic interest and breeding. Using light and electron microscopy, histochemistry and immunohistochemistry techniques, we report that: (1) Superficial fibre precursors originate close to the notochord, are part of the same cell population as the so-called muscle pioneer cells, and are transferred laterally to end up at the surface of the myotome.

Our data present the first demonstration of intraretinal variations of serotonergic substances under light/dark-conditions (LD) and during continuous darkness (DD). All substances examined (serotonin, N-acetyl serotonin, 5-hydroxytryptophol, 5-hydroxyindole acetic acid) were rhythmic in LD.

In a first attempt to show both morphological and neurochemical variations during light/dark conditions (LD) and during continuous darkness (DD), we investigated retinomotor movements and the associated regulatory transmitters, dopamine and melatonin. All parameters studied showed patterns of rhythmicity in LD and DD, clearly indicating the presence of an endogenous clock in the rainbow trout eye.
