In the second phase of this year's district fish stocking program 10,000 rainbow trout fingerlings were placed into waterways upstream from Lake Oberon, and another 1000 below the lake, in the Fish River on November 15
It is hoped that the fish above the lake will grow sufficiently so that when they reach the lake, they will be large enough to ward off the predatory redfin.
In the first part of the program, 20,000 rainbow fry were put into the district's rivers and streams last month.
The fish were supplied by the NSW Department of Fisheries hatchery at Ebor and were put into the waterways by Oberon branch of the Central Acclimatisation Society.
At the branch's recent annual meeting, the consensus was that the present fishing conditions were the best for 10 years.
