Pond Boss Forums INTRO Questions & Observations Ice, Snow, and Winter Fish Kill Potential

Yes if you have RES in the pond I would only aerate with the diffusers set close to shore or in the shallow end of the pond. RES are definitely a warmer water fish. Water temps of 36-38F will likely cause kills? If Cecil had his temperature gauge at home, I would have him go and check the deep water temperatures at various locations moving away from the shallow water diffuser until he got to the other end of the pond. There is still a lot to learn about winter aeration in sport fishing ponds.
