Murray cod (Maccullochella peelii) are a nationally listed threatened species, as well as the most sought-after recreational freshwater angling species in south-eastern Australia. Murray cod are well studied in the lowlands of the MDB, however little research is conducted in upland environments. This is in part because of the difficulty in using traditional survey methods (electrofishing) in the rocky, high gradient and narrow gorge country of upland rivers. With growing confidence in citizen science, and increasing interest from recreational anglers to be involved in the management of their fishery, there is an opportunity to develop novel cost-effective volunteer sampling techniques. This study used 24 volunteer anglers across 6 long-term monitoring sites in the upper Murrumbidgee River in the ACT, to capture and tag Murray cod during 3 events in 2015/16. Immediately following the angling surveys, researchers conducted boat electrofishing surveys allowing a capture efficiency comparison of the two sampling techniques. The mark-recapture data was also used to estimate site population. Across all 3 sampling events, 48 Murray cod were captured by anglers in 724 hours, while 149 Murray cod were captured by electrofishing in 37 hours. Angled fish length ranged from 295mm to 1140mm (median = 632.5mm), while electrofishing captured fish ranging from 82mm to 1075mm (median = 349mm). 51 fish (34.2%) captured by electrofishing were juvenile Murray cod under the minimum length of all angled fish. Although angling is a less efficient capture method, when used in conjunction with traditional survey techniques it could provide the basis for increasing the scope and frequency of future monitoring programs, particularly in upland rivers.
