Trophic webs of reef fishes in northwestern Cuba. I. Stomach contents. Studies on the reef fishes of Cuba are not rare, but most have two basic limitations: small sample sizes and exclusion of small species. Our study sampled more species and larger samples in the sublitoral region of Havana city (23 degrees 7.587' N, 82 degrees 25.793' W), 2-18 m deep. We collected fish weekly from October 2004 through February 2006 with traps and harpoon. Overfishing has modified the fish communities. We used the relative importance index to describe the diets of carnivore and omnivore species, and a modification of the relative abundance method for the herbivores and sponge-eating species. The main food items are benthonic crustaceans (crabs, shrimp, copepods) and bony fish (mainly demersal species). Most species are eurifagous and thus, less affected by anthropic disturbance than specialist feeders.
古巴西北部珊瑚礁鱼类的营养网络。I. 胃内容物。关于古巴珊瑚礁鱼类的研究并不罕见，但大多数研究有两个基本局限：样本量小以及排除了小型物种。我们的研究在哈瓦那市（北纬23度7.587分，西经82度25.793分）2至18米深的近岸浅水区对更多物种和更大样本进行了采样。我们从2004年10月至2006年2月每周用陷阱和鱼叉收集鱼类。过度捕捞已经改变了鱼类群落。我们用相对重要性指数来描述肉食性和杂食性物种的食性，并用相对丰度方法的一种改进形式来描述草食性和食海绵物种的食性。主要食物种类是底栖甲壳类动物（螃蟹、虾、桡足类）和硬骨鱼（主要是底栖物种）。大多数物种食性广泛，因此与特化觅食者相比，受人为干扰的影响较小。
