When is a carp not a carp!
Yesterday afternoon, we received a phone call from a concerned member of the public informing us of a carp caught on rod and line out of the Macquarie River. The fish was described as approximately 3.5kg, with barbels (whiskers around the mouth), and a carp shaped body. Although the fish was disposed of after capture, luckily the angler thought to take a few snaps of the suspect fish. After viewing these photographs, it was identifed as a a tench (Tinca tinca). Tench are in the same family as carp, and both fish are classed as Cyprinids. However tench are widespread in Tasmania, and are not regarded to be as destructive to native species and the environment, as carp.
Some key identifying features of carp which can distinguish them from other similar pest fish in Tasmanian waters is that they possess two pairs of barbels, have relatively large scales, and possess a hard serrated spine at the origin of the dorsal and anal fins.
We encourage the public to report any suspicious looking fish to the IFS as soon as possible. To aid in the correct identification of fish species, clear photographs with a scale are encouraged, as well as lengths and weights. If possible, the fish can also be retained and frozen. Carp are only found in Lake Sorell in Tasmania, and will hopefully be eradicated over the next few years.
