AbstractUsing modified clay is one of the most promising methods for the mitigation of harmful algal blooms (HABs). However, the environmental impact of modified clay has become a subject of global concern. In this study, turbot (Scophthalmus maximus L.) embryos were used as a model to assess the effect of modified clay on this sensitive stage of fish development. Results show that the 24 and 48h LC50 (median lethal concentrations) of the modified clay were 1.70 and 1.65 g/L, and the safe concentration was 0.47 g/L, which is much higher than the concentration used to treat HAB. The modified clay did not affect significantly the hatchability of turbot embryos but when the concentration exceeded 0.50 g/L, the deformity rate of newly hatched larvae increased significantly. The total length, specific growth rate (SGR) and yolk sac absorption rate of larvae reached their peaks at 0.50 g/L and then gradually decreased as the concentration of modified clay increased. Therefore, a moderate amount of modified clay does not harm the survival and hatching of turbot embryos, or the growth and development of newly hatched larvae.
