The present study represents the first documentation of the trophic spectrum of the deep-water bony fish Pagellus bogaraveo in two different habitats in the central Mediterranean Sea: muddy bottoms (MB) and cold-water coral (CWC) habitats. A total of 133 stomachs were collected on MB and 39 in CWC habitats. The feeding habit of P. bogaraveo was different in the two investigated habitats. A lower number of prey categories were found in CWC habitats (15) than on MB (36). Teleostei (%PSIRI = 38.29) and Crustacea (%PSIRI = 36.49) were the most important prey in MB. The taxon of Anellida was the most abundant in number and the third in importance. In CWC habitats Teleostei were the most abundant prey (%PSIRI = 62.03) and Ophiuroidea were the second important ones. Ontogenetic dietary variation was evident in both habitats. The comparison of the diet between the habitats was carried out considering two samples of specimens with overlapping sizes, 21 on MB and 18 in CWC habitats, ranging between 192 and 280 mm total length (TL) from the former habitat and 184 and 271 mm TL from the latter. Dietary differences were significant as shown both by Morisita's index and PERMANOVA. The habitat in which the species lives would seem to affect the trophic strategies of P. bogaraveo. The trophic niche breadth examined for comparable sized samples showed how P. bogaraveo was more generalist on MB (Bi = 0.406) and a little bit more specialist in CWC habitats (Bi = 0.301). P. bogaraveo resulted to occupy a higher position in the trophic web of the CWC habitats compared to that on MB.

本研究代表了地中海中部两个不同生境中的深水骨性鱼类Pagellus bogaraveo的营养谱的第一个文献记录：浑底（MB）和冷水珊瑚（CWC）栖息地。在MBC和CWC生境中总共采集了133个胃。博格拉维奥体育的摄食习性在两个调查过的生境中是不同的。在CWC生境中发现的猎物类别数量较少（15），而在MBC中则为36。硬骨鱼（％PSIRI = 38.29）和甲壳纲动物（％PSIRI = 36.49）是MB中最重要的猎物。Anellida的分类单元数量最多，重要性排名第三。在CWC栖息地中，Teleostei是最丰富的猎物（％PSIRI = 62.03），Ophiuroidea是第二重要的猎物。在两个生境中均存在明显的个体饮食差异。比较两个生境之间的饮食，其中考虑了两个样本的大小重叠，在CWC生境中MB上有21个样本，在CWC生境中有18个样本，前生境的总长度（TL）在192和280 mm之间，TL则是184和271 mm从后者。森里氏指数和PERMANOVA均显示出饮食差异显着。博加拉韦奥（P. bogaraveo）。对可比较大小的样本进行了营养小生境的研究，结果表明博古拉维奥杆菌在MB上更具通用性（Bi = 0.406），而在CWC生境中则更具专业性（Bi = 0.301）。P. bogaraveo导致占据了CWC栖息地的营养网络更高的位置相比于MB。
