The differentiation of the jaw adductor muscle of the rosy barb, Barbus conchonius, has been studied during development to determine the relation between fiber type and early muscle activity. First, a morphological description and a functional analysis with electromyography has been made of the jaw adductor of the adult fish. Based on this analysis and on histochemical characteristics, the jaw adductor muscle can be divided into two parts: an aerobic part, which shows contractile activity during respiration, and an anaerobic part, which is silent during respiration. Secondly, the jaw adductor muscle of embryonic and larval specimens of the barb was investigated (immuno)histochemically. From the fourth day after fertilization onwards, deeply located future-red fibers and more superficial future-white fibers can be distinguished histochemically. From the juvenile stage onwards (30 days after fertilization), the histochemical pattern of the jaw adductor is identical to that of the adult. Results are discussed in relation to the start of respiratory and feeding behaviour during development.
