Growth performance including final weight and specific growth rate (SGR) significantly increased with increasing feeding rate (p<0.05). The relationship between SGR (% per day) and ration level (% per day) was an asymptotic curve described as SGR = 0.2809X+1.4191. Feed efficiency ratio (FER) decreased significantly with increasing ration levels, and the relationship between FER and ration level (% per day) described as FER = -0.0586X+1.3184. Hepatosomatic index significantly increased with increasing feeding rate (p<0.05). Based on the above results, it may be concluded that a ration size of 8% of body weight per day is optimal for good growth and feed conversion efficiency of juvenile S. hasta in nursery phase.}, keywords = {Feeding rate,Nursery Phase,growth indices,Sobaity seabream}, title_fa = {اثرات میزان غذادهی بر رشد و کارایی تغذیه بچه ماهی صبیتی(Sparidentex hasta) در مرحله نرسری}, abstract_fa = {سطح تغذیه، مرحله نرسری، شاخص های رشد، ماهی صبیتی }, keywords_fa = {سطح تغذیه,مرحله نرسری,شاخص های رشد,ماهی صبیتی}, url = {https://isfj.areeo.ac.ir/article_116929.html}, eprint = {https://isfj.areeo.ac.ir/article_116929_866b8c8d9436c808ea213ac7152a5bed.pdf} }
