growths on provo fish

[RipNLips]

The condition is called Saprolegniasis. Saprolegnia is a water mold that is common in virtually all fresh water systems. Though always present, it usually can't get a good parasitic hold on a fish unless the fish is already stressed for some reason. Many environmental factors can be the cause of the stress. The trick is to figure out what factors are causing the stress. It's usually not just one factor, in fact, it's usually several factors combining to create a stressful environment. The spawn itself is a stressful time for trout, and that's probably what finally got their stress level high enough this year.

Here are a couple links for more info...

Here's a link where an angler gives HIS opinion about the "white fungus" on fish in the Provo. While reading his article, remember that several environmental factors are probably the cause of the stress, not just one (i.e. food supply).
