Effects of incubation temperature on muscle morphology and growth in the pacu (Piaractus mesopotamicus)

Expression of Growth-Related Factors in Skeletal Muscle of Pirarucu(Arapaima Gigas) during Growth

“…Therefore, based on our results, we suggest that stratified hyperplasia also contributes to a great increase in pirarucu's muscle mass. The expression of the MyoD and myogenin genes, as well as their related proteins in white muscle were not different among the several analyzed stages, which is consistent with many other studies [15][16][17]69,70] and may be attributed to the large requirement of fibers for studied groups (p values: 0.2063 and 0.4533, respectively), indicating that these genes contributed similarly during the whole period of growth from young to juveniles. In contrast, myostatin levels exhibited significant variation.…”

Histological comparison of the dorsal ordinary muscles of wild and full‐cycle cultured Pacific bluefin tuna (Thunnus orientalis)

“…31 The results of this study indicate that the difference in breeding form (wild or culture) affects the growth of ordinary muscle fibre of tuna.…”

Comparative organ differentiation during early life stages of marine fish

“…The myotomes become progressively more complex in shape as they interdigitate with growth. In the first developmental phases of most teleosts, the myotomes are composed of presumptive white immature fibers surrounded by a monolayer of small embryonic red fibers, these can be more differentiated in some species [54]. The red muscle is initially present as a superficial cylindrical sheath around the body, but it later becomes concentrated in a midlateral strip [12,24,36].…”
