Abstract[1] This experiment examined the effects of Tenebrio molitor larvae as a supplementary diet on some growth performance and survival of Acipenser nudiventris juveniles in 2012 in the ornamental fish hatchery of Tehran city. The number of juveniles considered for this project, 180 juveniles, with mean initial weight and length, respectively, 3.4±0.06 gr and 6.2±0.095 cm that all sturgeon research institute Doctor Dadman Guilan were obtained from the experimental plots. 12 pcs glass aquarium dimensions (30×70×30) cm comprised the wells were filled. Operation of fish bioassays carried out every two weeks and the weight factor, length, specific growth rates, feed efficiency, protein efficiency ratio, feed conversation ratio and survival rate were studied. The test results showed no significant differences between the mean percent weight factor, percent elongation, specific growth rates, feed efficiency, protein efficiency ratio, feed conversation ratio (P>0.05). Results indicated that use this larvae to 6% in the supplementary diet improve fish growth requirement, although no significant differences were observed between treatments. * Corresponding Authors; Email: leilacheraghalizadeh@yahoo.com
