The genetically modified (GM) rice Bt-ShanYou63 (Bt-SY63) received an official biosafety certificate while its safety remained in dispute. In a lifelong study, Daphnia magna were experimentally fed a basal diet of rice flours from Bt-SY63 or its parental rice ShanYou63 (SY63) at concentrations of 0.2mg, 0.3mg, or 0.4mgC (per individual per day). Overall the survival, body size, and reproduction of the animals were comparable between Bt-SY63 and ShanYou63.. The results showed that no significant differences were observed in growth and reproduction parameters between D. magna fed GM and non-GM flour and no dose-related changes occurred in all the values. Based on the different parameters assessed, the GM rice Bt-SY63 is a safe food source for D. magna that does not differ in quality from non-GM rice.
转基因水稻Bt-汕优63（Bt-SY63）获得了官方生物安全证书，但其安全性仍存在争议。在一项长期研究中，以0.2毫克、0.3毫克或0.4毫克碳（每天每只个体）的浓度，用Bt-SY63或其亲本水稻汕优63（SY63）的米粉作为基础饲料，对大型溞进行实验喂养。总体而言，Bt-SY63和汕优63喂养的动物在存活、体型和繁殖方面相当。结果表明，喂食转基因和非转基因面粉的大型溞在生长和繁殖参数上没有观察到显著差异，且所有数值均未出现剂量相关变化。基于所评估的不同参数，转基因水稻Bt-SY63对大型溞来说是一种安全的食物来源，其质量与非转基因水稻无异。
