The First Record of Parachromis managuensis (Günther, 1867) (Cichliformes, Cichlidae) and an Analysis of its Feeding Habits in Jamaica
Abstract The first official record of Parachromis managuensis in Jamaica is reported in the Large Cockpit Spring, Clarendon. This species is native to Central America. It was introduced into Jamaica to control the growth of aquaculture species. A total of 104 specimens were captured between December 2017 and March 2020 using seine nets. Morphometric and meristic descriptions are provided. Specimens captured had total lengths of 3.663–11.797 cm and weighed 0.787–36.810 grams. All specimens were classified as juveniles. Gut content analyses were conducted, which revealed that Parachromis managuensis mainly fed on invertebrates which include insects, ostracods, and gastropods. Ostracods were ranked as the most important food item. Other food items include algae and plant matter.
