毛嵌线螺（ Ｃｙｍａｔｉｕｍ ｐｉｌｅａｒｅ）的繁殖过程包括交配、产卵、孵育及幼虫从卵囊中游出等４个阶段．交配一般在产卵前１０～１５ｄ进行，产卵后母体并不离开卵群，而是持续静伏在卵群的开口上进行孵育，直至其中的幼虫离开卵囊．温度和盐度对毛嵌线螺受精卵的发育有重要影响，在２２～３０℃的适宜温度区域内，将受精卵孵育成能自由生活的晚期面盘幼虫需４３８日度左右的总积温．毛嵌线螺受精卵的发育与其他前鳃类腹足动物相似，包括卵裂、囊胚期、原肠期及面盘幼虫期４个阶段．
The breeding process of Cymatium pileare includes mating, spawning, incubation and larval migration from the oocyst in 4 stages. Mating is generally carried out 10-15 days before spawning. After spawning, the mother does not leave the egg population, but keeps on standing on the opening of the egg population until the larvae therein leave the oocyst. The temperature and salinity have an important influence on the development of Schizothorax larvae. In the suitable temperature range of 22-30 ℃, the late accumulated larvae of hatching larvae which are free to live should be about 438 days in total. The development of Schizothorax is similar to other Gill gastropods including cleavage, blastocyst, gastrula and larval stage.
