I found out that fly fishing is more successful than lure casting in Clearwater Sanctuary. Out of many peacock basses I caught, only one fish took my spinner even though I used a variation of lures. The rest were by fly fishing.
I'm not saying that fly is the best way to fish peacock bass here, I think that the Peacock bass here are not easily tricked by using lure. The fish are getting smarter because of the fishing pressure by the visitors.
