Clostridium autoethanogenum protein (CAP) is a promising protein source but high dietary level of CAP was proved to reduce the growth performance and quality of aquatic animals. In order to evaluate the combination of hydroxyproline, taurine and cholesterol (HTC, with the proportion of 1:1:2) to overcome the disadvantage of CAP, six experimental diets were formulated, in which CAP was used to replace 45 %, 60 % or 75 % of fishmeal protein in a fishmeal-based diet to prepared three diets and HTC was added to these three diets at the level of 2 % for another three diets. These diets were fed to turbot Scophthalmus maximus with the initial weight of about 211.6 g for 8 weeks. The results showed that HTC added to diets with 45 % and 60 % of fishmeal replacement levels led to significant increases in final body weight, weight gain rate, muscle springiness, muscle chewiness and expression of myod and myhc (P
