The stomachs and spiral valves of sharks and rays were examined for their trypanorhynch (Cestoda) parasite fauna and dietary items to infer feeding ecology. In Indonesia, sharks and rays have been experiencing increasing awareness and conservation in the recent years due to high fisheries activities and to avoid future species extinction.
The samples were collected in 2009 from two different sampling sites at the southern coasts of Java and Bali in Indonesia. The parasite fauna was studied for 41 elasmobranch fishes. Amongst these, three shark species, Carcharhinus sorrah, Carcharhinus sp. I and Squalus megalops and seven ray species, Brevitrygon heterura, B. cf. heterura, Gymnura zonura, Maculabatis gerrardi, Mobula kuhlii, Neotrygon cauruleopuncatata and Rhinobatos penggali were studied. Four additional specimens, belonging to the shark species Carcharhinus sp. II and Mustelus cf. manazo and the ray species Maculabatis gerrardi were studied from the waters of South Bali.
Analyses of the feeding ecology of the ray M. gerrardi revealed distinct differences between both sampling sites, indicating the presence of ecological differences between the geographically independent regions. A total of 11 different trypanorhynch species/taxa belonging to the five families Eutetrarhynchidae (5), Gilquiniidae (1), Lacistorhynchidae (1), Pterobothriidae (1) and Tentaculariidae (3) were found. Ten trypanorhynch species from Penyu Bay and four species from South Bali could be identified. Two taxa that might represent new species were collected: Dollfusiella sp. from Brevitrygon heterura and Prochristianella sp. from Maculabatis gerrardi.
The present paper gives insights in using the trypanorhynch cestode community in combination with feeding ecology analyses to support conservation of elasmobranchs in Indonesian waters.
对鲨鱼和鳐鱼的胃及螺旋瓣进行检查，以了解其异吻绦虫（绦虫纲）寄生虫群落和食物种类，从而推断其摄食生态。在印度尼西亚，由于渔业活动频繁，为避免未来物种灭绝，近年来鲨鱼和鳐鱼受到了越来越多的关注和保护。
2009年在印度尼西亚爪哇南部海岸和巴厘岛的两个不同采样点采集样本。对41种板鳃鱼类的寄生虫群落进行了研究。其中，研究了三种鲨鱼，即沙拉真鲨、未鉴定的真鲨属物种I和大眼角鲨，以及七种鳐鱼，即异尾短鳐、疑似异尾短鳐、环纹裸胸鳐、吉氏黄斑魟、库氏蝠鲼、蓝点新鳐和彭氏犁头鳐。另外，从巴厘岛南部海域采集了四个额外的样本，分别属于鲨鱼物种真鲨属物种II和疑似日本鼬鲨，以及鳐鱼物种吉氏黄斑魟。
对吉氏黄斑魟摄食生态的分析显示，两个采样点之间存在明显差异，表明在地理上独立的区域之间存在生态差异。共发现了11种不同的异吻绦虫物种/分类单元，分属于五个科，即真四吻科（5种）、吉尔奎尼科（1种）、袋吻科（1种）、翼槽科（1种）和触手科（3种）。可以确定来自Penyu湾的10种异吻绦虫物种和来自巴厘岛南部的4种物种。收集到两个可能代表新物种的分类单元：来自异尾短鳐的多尔夫西绦虫属物种和来自吉氏黄斑魟的原克里斯蒂绦虫属物种。
本文介绍了利用异吻绦虫群落结合摄食生态分析来支持印度尼西亚海域板鳃鱼类保护的相关见解。
