The food and feeding habits of Cardisoma armatum Herklots, 1851 was investigated in Ehotile Islands National Park from January to December 2018. A total of 355 cardiac stomachs were examined, and the diet studied according to size, sex, and seasons. The relationship between the length of the intestine (Li) and carapace (Lc) was found to be log Li = –0.3203 + 1.0064 × log Lc. The relative importance of food (RIF) showed that C. armatum has an omnivorous diet with insectivorous tendency. Macrophytes, insects, crustaceans, molluscs, fishes, and oligochaete worms were the major feed. Macrophytes (RIF 64.17%) was the main prey, insects (RIF33.6%) a secondary prey, while molluscs (RIF 1.26%), crustaceans (RIF 0.7), fishes (RIF 0.14%), and oligochaetes (RIF 0.13%) were incidental prey. Macrophytes and insects were respectively the primary (RIF 59.35% and 57.79%) and secondary (RIF 37.51% and 39.33%) prey consumed by juveniles (Lc ˂ 64.44 mm) and adults (Lc ≥ 64.44 mm). There was a significantly different diet between males and females (P ˃ 0.05), between rainy and dry seasons (P ˃ 0.05) and a similar diet composition between juveniles (P ˂ 0.05) and adults (P ˂ 0.05).

西非科特迪瓦陆蟹 Cardisoma armatum (Herklots, 1851) (十足目: Brachyura: Gecarcinidae) 的食物和摄食习性

2018 年 1 月至 2018 年 12 月在埃霍蒂尔群岛国家公园对 Cardisoma armatum Herklots, 1851 的食物和摄食习惯进行了调查。总共检查了 355 个心脏胃，并根据大小、性别和季节研究了饮食。发现肠长 (Li) 和甲壳 (Lc) 之间的关系为 log Li = –0.3203 + 1.0064 × log Lc。食物的相对重要性（RIF）表明，C. armatum 具有杂食性，具有食虫倾向。大型植物、昆虫、甲壳类动物、软体动物、鱼类和寡毛类蠕虫是主要饲料。大型植物（RIF 64.17%）是主要猎物，昆虫（RIF33.6%）是次要猎物，而软体动物（RIF 1.26%）、甲壳类动物（RIF 0.7）、鱼类（RIF 0.14%）和寡毛类动物（RIF 0.13%）是偶然的猎物。大型植物和昆虫分别是主要的（RIF 59. 35% 和 57.79%) 和次要 (RIF 37.51% 和 39.33%) 猎物被青少年 (Lc˂ 64.44 mm) 和成人 (Lc ≥ 64.44 mm) 消耗。雄性和雌性之间的饮食有显着差异（P˃0.05），雨季和旱季之间（P˃0.05）和青少年（P˂0.05）和成年人之间相似的饮食构成（P˂0.05）。
