It all depends how much you are looking to spend. If you're looking for a point and shoot camera, you have about a dozen choices. If you want a DSLR you have Canon and Nikon. I worked as a professional photographer for 7 years. In my experience, I can say that generally you get what you pay for. One of the most important things to look for is a fast lens, large aperature lens. Try to get one that opens up to F2.8 at the wide zoom. Another handy feature on most cameras these days is HD video. I find myself shooting more video than I do pictures these days. With HD you can pull decent stills from the video.
Fujifilm and Panasonic produce amazing images. Very sharp and good colour reproduction. I believe most Panasonic point and shoots use Leica lenses. Can't go wrong with Leica glass.
Personally, for fishing I use a Pentax WS80. Its ok. But I would not recommend it. There is too much image noise at higher ISOs. Its great in good lighting but not so good otherwise.
