Abstract Three groups of turbot, Scophthalmus maximus L., were reared at three different temperatures ( T s) from hatching until 150 d posthatching: warm (21–22 C), ambient (17–18 C), and cold T (15–16 C). Later on, all of them were transferred at ambient T until the end of the experiment (1.8 yr of age, at commercial size: ≈1.5 kg and 40 cm) in order to study the long‐term T effect on the growth. At 1 yr of age, almost all the muscle and body parameters were greater in the warm than in the rest of the groups. At 1.8 yrs of age, the reverse situation was found, such that almost all the muscle and body parameters were higher in the cold than in the rest of the groups, thus showing a compensatory growth in the cold group. In relation to the texture parameters, most of them did not show significant differences among the groups. In relation to the sex influence, the size of muscle fibers was lower in the female than in the male fish, whereas the number and the muscle fiber density were generally higher in female than in male fish. The texture parameters did not show significant sex influence.
