Fin Clipping at Gaden hatchery

Each year the Government hatchery at Jindabyne tops up Lake Eucumbene with rainbow trout fingerlings. A portion of those fingerlings are anaesthetised and fin clipped by volunteers as part of a program to monitor the success of the fish stocking – 2013 fingerlings are minus the right pectoral fin so look out for fish swimming clockwise next year.  This year’s Jindabyne hatchery fin clipping event attracted a good crowd of volunteers – so good it was all over in a day.  Not only that DPI fisheries were proudly sporting their new high tech wire tagging machine (literally out of the box the night before) that inserts a micro tag in the snout of a 50mm fingerling. Top science.

The fin clipped trout can be visibly seen by the technicians electro fishing the spawning run, whilst the wire tag can be detected with the aid of a hand held machine. Both help to monitor the contribution of stocked fish to the total population, as well as age and growth rates.
