Fished 7am to 9am today caught and released 4 males , lost another three all in the first 45 minutes. From 7 to 8 the bite was really on, more fish surfacing and jumping than I've seen so far this year, and everyone was getting fish. Then there was a period of the fish being visibly there but no hookups. By 8:15 there were a few (say one per minute) splashes and jumps but no-one even got a nibble.
From my observations, it almost doesn't matter what lure you have. I've been watching people either side of me fish spoons, jigs, buzz bombs, spin-n-glows, spinners under floats, spinners on their own, pink worms. I fish with a pink/silver croc and I'm consistently out fishing them not because of the lure, certainly not with skill or knowledge, but the fact that my lure is in the water for much more time than theirs. Personally, with my rod and line combination, I find I can cast a spoon much further than I can a spinner and then I retrieve it as slowly as I dare. I get hookups way out and I get them close in. That said, maybe I'm just lucky.

.......glad I have tomorrow off, back again same time same place - hope the luck holds out. I get the sense however that the very best fishing is still ahead of us and the numbers going upstream are increasing.
