摘要

摘要本文首次通过胃内容物对北非淡水蟹阿尔及利亚肥蟹的饮食组成进行了研究。螃蟹是在2018年10月至2019年9月的一年时间里从摩洛哥东北部的一条山间溪流Oued Zegzel收集的。在捕获的72只螃蟹中,只有35只雄性和30只雌性有可以分析的胃内容物。采用发生频数法和百分数法进行饮食成分分析。胃内容物分析表明,阿尔及利亚p.a lense是一种机会性杂食性动物,能够摄取植物和动物材料,以植物组织为主。摄食指数在夏季至深秋期间较高;然而,在雨季记录的数值较低。

Diet composition of the North African freshwater crab, Potamon algeriense (Bott, 1967) in Oued Zegzel (Northeast of Morocco)
ABSTRACT This is the first study of the diet composition of the North African freshwater crab Potamon algeriense by examining stomach contents. Crabs were collected during 1 year, October 2018 to September 2019, from Oued Zegzel, a mountain stream in the Northeast of Morocco. From a total of 72 crabs captured, only 35 males and 30 females had stomach contents that could be analyzed. Diet composition analysis was carried out using the frequency of occurrence and the percentage point methods. Stomach content analysis showed that P. algeriense was found to be an opportunistic omnivore capable of ingesting both vegetal and animal materials, with a predominance of vegetal tissues. High values of the feeding index were observed from summer to late autumn; however, lower values were recorded during the wet season.

期刊介绍: Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
