Abstract
The red claw crayfish Cherax quadricarinatus has been a globally important aquaculture species ever since the late 1980's and was introduced to Jamaica for cultivation in 1993. However, populations of C quadricarinatus have become established in at least two natural freshwater systems the Rio Cobre in St. Catherine, and the Black River in St. Elizabeth. As a polytrophic species, there is a potential risk that the red claw crayfish may induce changes in habitat and community structure, thus harming the indigenous fauna. This study intends to establish the impact of this Australian native in Jamaican rivers. This involves the investigation of key biological factors such as diet and reproduction, as well as the ecological interactions of C. quadricarinatus with both native and exotic macroinvertebrate species.....
