Hi Mate
I used to go to Loch Sport a lot. Probably been fishing there over 100 times and fished the lake dozons of times, and never caught anything land based in the lake except for eels once. But thats just me. Other people might have had better luck.
Loch Sport is most known for its surf fishing. Get yourself a surf rod and rod holder and give it a go. I have caught more species than I can remember off the surf including the occasional bream, whiting, mullet, flathead, taylor, gummy banjo, skate, rays, Unknown shark species, Salmon, couta, snapper, and more.
