New / Farrington fish kill

[NJBassAngler]

Hi everyone, new to the site! I do a majority of my fishing in the middlesex county area, with an occasional trip up to the passaic river. This morning I went to Farrington Lake for pike. I tried a few different spots from Davidsons Mill Rd up to Lake View Day Camp, with no luck of course but that's a different subject. What I did see though was a lot of dead bluegills and crappies, some floating on the top and others already at the bottom. At the last spot I tried there was a decent catfish, dead along the shore. It had some weird shit growing on its face. Attached photo.
