My uncle owns a property near Goulbourne, he has 3 sized dams. One big, one small and one inbetween, anyways, he stocked all 3 of them with trout and silver perch. The first time I ever went there we were catching perch after perch all 40cm+, but not 1 trout. Anyways its been 5 years since then, and I havent seen a living thing come out of those dams now.
Its good to see a picture of one of those fish again, and congratulations on a massive one like that.
