日本宫崎县水产试验场采取压缩雌鱼腹部再切开，人为取出仔鱼的方法，成功地大量生产了褐菖鲉的稚鱼。褐菖鲉为卵胎生，产出的不是卵，而是长约3mm的仔鱼。一尾雌鱼一次可产5000-20000尾仔鱼，但要在大约一周的时间内分数次产出。因此，产仔后水槽中的仔鱼发育不同步，小的仔鱼 Japan’s Miyazaki Prefecture aquaculture trial site to take compressed abdominal re-incision, artificially remove the larvae successfully mass-produced brown shrimps larvae. Brown calamus oviparous, the output is not eggs, but about 3mm larvae. A female fish can produce 5000-20000 tail larvae at a time, but in a week or so in a fraction of output. Therefore, larvae in the litter after litter development are not synchronized, small larvae
