Abstract：
This study was conducted to determine the senses that facilitate prey detection in the marble goby (Oxyeleotris marmorata) larvae. The ingestion ratios of live (generate chemical and mechanical stimuli) or frozen Artemia nauplii (generate chemical but no mechanical stimuli) by the intact or free neuromast (mechanoreceptor)-ablated O. marmorata larvae (11 mg/L streptomycin treatment before feeding) under the light or dark (fish vision was obstructed) condition were examined. Vision, mechano-, and chemoreceptions were all found to be essential in prey detection of the O. marmorata larvae. Prey movement has a significant influence as a visual stimuli on the O. marmorata larval feeding as the Artemia nauplii ingestion ratio was approximately 40% higher with significant (p = 0.001, d = 3.0), when the intact larvae were fed with the live (78.1 ± 1.5%), rather than the frozen (40.9 ± 2.8%) Artemia nauplii, under the light condition. This result was assured when no significant difference (p = 0.572, d = 0.2) was found between the ingestion ratios of frozen Artemia nauplii by the intact O. marmorata larvae under light and dark conditions. These findings demonstrate that prey detection in the O. marmorata larvae was facilitated by multi-modal senses, allowing O. marmorata larvae to survive in their natural habitats.
摘要：
进行这项研究是为了确定促进大理石虾虎鱼（Oxyeleotrismarmorata）幼虫中猎物检测的感官。在光照或黑暗（鱼视力受阻）条件下，完整或游离的神经肥大（机械感受器）消融的O.marmorata幼虫（喂食前11mg/L链霉素处理）对活（产生化学和机械刺激）或冷冻无节幼体（产生化学但无机械刺激）的摄取率进行了检查。愿景,机械-，和化学感受都被发现对于O.marmorata幼虫的猎物检测至关重要。猎物的运动作为视觉刺激对O.marmorata幼虫的摄食有显着影响，因为卤虫无节幼体的摄食率高出约40％，具有显着意义（p=0.001，d=3.0），当完整的幼虫被喂食时（78.1±1.5％），而不是冷冻的(40.9±2.8%)无节幼体，在光线条件下。当在光照和黑暗条件下，完整的O.marmorata幼虫对冷冻无节幼体的摄食率之间没有显着差异（p=0.572，d=0.2）时，可以确保这一结果。这些发现表明，多模态感官促进了O.marmorata幼虫的猎物检测，允许O.marmorata幼虫在其自然栖息地中生存。
