摘要

摘要：在牙买加的克拉伦登的大Cockpit Spring首次记录到了马纳盖副铬虫（Parachromis managuensis）。本种原产于中美洲。它被引入牙买加是为了控制水产养殖物种的生长。2017年12月至2020年3月期间，使用围网共捕获了104个标本。提供了形态计量学和分生组织学描述。捕获的标本总长度为3.663–11.797厘米，重量为0.787–36.810克。所有标本均被归类为幼年标本。进行了肠道含量分析，结果表明，马那盖副铬虫主要以昆虫、介形虫和腹足类等无脊椎动物为食。鸵鸟被列为最重要的食物。其他食物包括藻类和植物。

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.
