一、催产和仔鱼的培育方法进行人工育苗研究,大量健康的初孵仔鱼不可缺少。当前获得鳗鲡受精卵主要还是依靠人工授精,不过,志布志栽培渔业中心已经开发了诱导自然产卵方法:将雌鳗和雄鳗放入同一水槽,并予以升温刺激(+2℃)促进自然产卵。已确定了适宜的诱导成熟和产卵温度条件,每周可以得到大量优质的受精卵,解决了仔鱼稳定供应的问题。将仔鱼培育成为白仔鳗的方法:培养容器是用10L的圆形水槽,为操作方便,数个至数十个水槽并列放于高度适宜的架子上(图1)。喂养仔鱼(柳叶鳗)的饵料是以鲨鱼卵为主体成分的液状饲料。投饵时,停止注水,开灯照明,将饲料用加样枪等注入到水槽底部(图2),
First, the method of cultivation of oxytocin and larvae Artificial breeding studies, a large number of healthy early hatching larvae indispensable. Currently, the fertilized eggs of Anguilla eel mainly rely on artificial insemination. However, the Shibuchi Cultivated Fishery Center has developed a method of inducing natural spawning by placing female eel and male eel into the same sink and stimulating natural spawning by warming (+ 2 ° C). Adequate induction of maturation and spawning temperature conditions have been established and large numbers of good quality fertilized eggs can be obtained weekly, addressing the problem of stable supply of larvae. The method of cultivating larvae as white eel: The culture container is a circular 10L tank, for ease of operation, several to dozens of sink side by side placed on a suitable height shelves (Figure 1). Feeding larvae (willow eel) is a liquid feed consisting mainly of shark eggs. When feeding, stop watering, turn on the light, inject the feed into the sink at the bottom of the sink (Figure 2)
