So ice came and went and no fish caught. I put 29 bluegill in through the ice and when the ice melted there were 2 dead gills and the one small perch I planted. The one gill had dirt on it so I'm hoping the others aren't dead on the bottom. I see no fish when I look in from the dock and threw some bread out and nothing ate it...

So what do I do next? I want perch and gills to thrive. Is there a water testing kit I can buy and see what's going on? Also there are signs of muskrats...
