Mangrove habitats such as those at Salt River, Jamaica are considered to be nurseries for juvenile fishes as they provide shelter from waves. These habitats are highly productive, leading to increased food availability, and the complex mangrove terrain allows juvenile fishes to evade larger predators. The role of small and juvenile piscivores has been widely overlooked, and one hypothesis suggests that their presence in an ecosystem exerts considerable predation pressure on the new recruits. The diets of five piscivores that inhabit Salt River and the adjacent shores (Caranx hippos, Gobiomorus dormitor, Sphyraena barracuda, Tylosurus crocodilus, and Lutjanus apodus) were examined. The working hypothesis for this study was that the piscivores that inhabit Salt River do not prey on the more abundant secondary consumers in this ecosystem, but rather compete with them for similar resources. The stomach analyses revealed that three of the five piscivores fed on fishes in varying amounts. Tylosurus crocodilus had a high feeding index of anchovies, amphipods, and fish remains. Lutjanus apodus had a high feeding index of fish remains, decapods, amphipods, anchovies, and crustacean remains. For Sphyraena barracuda, the highest feeding index was fish remains. Caranx hippos fed on oligochaetes and polychaetes, and Gobiomorus dormitor fed predominantly on amphipods.
