2000 Trout Missing in Rowbank

Gave it four hours yesterday, 15th March, not even a touch. Tried again today, managed one 3/4 lb stockie for five hours effort. With 2000 fish put in 6 weeks ago it should be a bonanza at the moment, whats going on? Maybe the cormorants have eaten them all who knows. Anyway the new intermediate line i was using is casting well and the new reel is performing fine so far, at least i have my first Brown trout of the season under my belt, lets hope the fishing picks up and some more fish begin to show up. It wasnt a bad day today, although it was wet all day with low mist and a strong south west breeze. I caught the fish on a Bibio to an intermediate line.
