I suprises me too, as the water has been cold and this fungus is temperature related prefering lower temperatues. Any morts we see at this time of the year always have a nasty spike mark in the top of the back, in front of the dorsal, but as you say, thats another story. We used to treat saprolegnia before we saw it with a pellet called 'Response' from Skretting. It has lots of vit C and a derivitve of mushrooms included and it is fed before any predicted stress event such as spawning or grading in cold weather. With the days drawing out and the sun getting warmer (you know what I mean) it looks like you might get off without any trouble at all. Perhaps, as saprolegnia is secondary, the fish might not have so many leeches or argulus. Populations of these parasites can be high some years and low during other winters.
