中文摘要：

2006年～2008年进行扁吻鱼人工繁殖研究期间，比较了不同孵化方法的孵化效果。结果表明：孵化盘和网箱孵化的静水孵化效果最差，孵化率不足70％；桶式孵化器孵化率在63％-90％，随孵化密度的增大，孵化率明显下降；“新水孵化器”的孵化率在95％以上，并有效结合了水流和水温等问题，该孵化方法可为裂腹鱼类和其他名优鱼类的孵化提供借鉴，具有可控温、用水量少、管理方便、出苗整齐，制作简易、成本低等优点。

英文摘要：

Several methods were selected to the experiment of hatching technology of Aspiorhynchus laticeps from 2006 to 2008. Effects of hatching plate and hatching crib in static water were the worst, and thesethe hatching rates were insufficient was lower than 70%. The hatching rates of barrel type hatchibator with flowing water wereranged from in 63%-% to 90%, but the hatching which dropped obviously rates obvious drop along with hatching the hatching density enlargementincreased. XinShui Hatchibator effectively combined the water flow and water temperature and other issuesfactors, then it hashad a lot of advantages such as temperature control, water-saving, easy management, fry specification neat, making simple and 1, low cost. Its hatching rates were was above 95%. , Therefore, it may provide reference for mountian carps （Schizothoracinae） and other famous fish.
