试验结果表明:在海蜇(RhopilemaesculentaKishinouye)养殖过程中,褶皱臂尾轮虫(Bra chionusplicatilis)、细巧华哲水氵蚤(Sinocalnustenellus)、近亲真宽水氵蚤(Eurytemoraaffinis)、蒙古裸腹水氵蚤(Moinamongolica)和卤虫(Artemia)无节幼体,均可作为幼蜇的饵料,在水温22～25℃,pH8 4～8 8,溶氧4～8mg/L,盐度30±0 5的条件下,培养22d幼蜇日生长率为1 2%～3 2%,成活率为100%。其生长率与试验饵料的种类关系不大,而与投喂密度有关。轮虫的合适密度为0 5×104～1 0×104/L。笔者还根据试验结果,以等生物量法,提出了投喂其它几种生物饵料的参考密度指标。以期为海蜇的人工养殖寻找更加广阔的饵料资源。
The results showed that during the breeding process of Rhinopithecus fruticosus, Rhizoctonia solani, Brachionus plicatilis, Sinocalnus tenellus, the close relatives of Eurytemoraaffinis, Moinamongolica ) And Artemia nauplii can be used as food for juvenile stings. Under the condition of water temperature 22 ~ 25 ℃, pH 8 ~ 8 8, dissolved oxygen 4 ~ 8mg / L, salinity 30 ± 0 5, On the 22th day, the growth rate of juvenile stings was 12% ~ 32%, and the survival rate was 100%. Its growth rate and the type of test feed little relationship, but with feeding density. The appropriate density of rotifers is 0 5 × 104 ~ 1 × 104 / L. According to the test results, the author also proposed the reference density index for feeding several other biological feedstuffs by the method of equal biomass. With a view to the artificial breeding of jellyfish to find a broader feed resources.
