幼虫曾四次成功从卵中孵化出来。卵是从地中海和红海（亚喀巴湾）标本中获得的。有三次通过剥离成熟成虫获得卵并受精。第四次产卵由圈养鱼在2000升水箱中自然产卵并受精。受精卵在29-30小时内孵化。孵化后，将幼虫放入各种尺寸的水箱（1至2000升）中。温度和盐度保持在恒定水平。幼虫在受精后4-5天开始取食，最后的存活者在自由取食8-9天后死亡。在较大的水箱中，幼虫的存活率最高。
LarvalSiganus rivulatuswere successfully hatched from eggs on four occasions. Eggs were obtained from both Mediterranean and Red Sea (the Gulf of Aqaba) specimens. On three occasions eggs were obtained and fertilized by stripping mature adults. The fourth time eggs were spawned and fertilized naturally by captive fish in a 2000-liter tank.Fertilized eggs hatched in 29–30 h. Upon hatching, the larvae were placed in various size tanks (1 to 2000 liter). The temperature and salinity were maintained at a constant level. Larvae began to feed 4–5 days after fertilization and the last survivors died after 8–9 days of free feeding. Survival of larvae was highest in the larger tanks.
