Common carp (Cyprinus carpio L.) are a relatively recent invader of the Glenelg River system (circa 2001). The Glenelg Hopkins Catchment Management Authority (CMA) is currently developing a strategy to slow their spread through the system and manage sites where carp are present to reduce their impact on native fish and overall river health. Key to the development of a cost effective carp control strategy is knowledge of the movement patterns and habitat preferences of carp which may be exploited for control purposes, as well as an understanding of the carp population dynamics and the efficiency of potential carp control techniques within targeted systems. This talk will present the results of a four year study that: 1) utilised acoustic telemetry and geospatial modelling to investigate carp movement patterns, 2) investigated the influence of environmental factors (i.e. temperature and flow) on movement, 3) evaluated feasible options for harvesting carp within the Glenelg River, 4) estimated the total numbers and density of carp within the system and, 5) integrated these data and provided strategies for a cost effective carp control program for the Glenelg River.
