Firstly if you get anything other than an SLR you'll be wasting your money. Good fishing photographs need a high speed capability and the ability to see exactly what you are shooting. That's pretty tough with the "point and shoot" style. I'd stick with either Nikon or Canon, they have all the various models to get the deal you want and their optics and sensors are first class. You need to have a good burst feature that allows you to leave your finger on the shutter button with the control set on "continuous". The auto focus on these cameras is fast enough to cope with that as well. Don't get too hung up on meg pixels either. You really don't need more than 10 or 12.
