| 摘 要： | 在人工养殖条件下，幼海马对投喂的饵料具有选择性，不同的饵料对幼海马生长和成活影响很大。幼海马在不同生长阶段摄食不同的饵料，随着幼海马体长增加，捕食对象也逐渐增大。根据幼海马胃内含物的检出率和占胃率发现，刚出生的幼海马适宜饵料为轮虫和单细胞藻类，随后最适饵料逐渐变为枝角类、桡足类。当幼海马能摄食枝角类和桡足类后，生长速度加快，这两类饵料生物在幼海马胃内总占胃率与生长速度的关系式为：y＝8．93431n x-18．6628(r＝0．9021，r0.05＝0．8780，r＞r0.05)。

| Abstract: | Abstract: Under intensive conditions, young sea horses are inclined to some fo od s, and different foods have great effects on their growth and survival. Young se a horses at different growth phases swallow different foods. Along with their gro wth, volumes of food organisms of sea horses become bigger and bigger. According to the detection frequency and victual rate in stomachs young sea horse, the m ost favorite foods of natal sea horses are rotifer and single cellular algae, th en are cladocera, copoda. When young sea horses are feed with the later, they gr ow much faster. The relation between growth rate and the victual rate of the two kinds of foods can be expressed as: y8.9343ln x-18.6628 r0.9021, r 0.050.8780, r>r .05 |
