    Hello its been a few years since I've posted here to the forum. I'm posting now because I have a new question. We have a couple of ponds only about an acre each in size. One of them near my house is where last summer we introduced some muscovy ducks. The number has fluctuated with about 10 at most. Late last summer we had an algae bloom in that pond and it lowered the dissolved oxygen in the water enough to kill some of the largest fish. I like to keep the algae off of that pond so we can swim as well. It's the first fish kill we've had in a few years and I was wondering if it was related to the excess nutrients, nitrogen and phosphorous, in the water due to the waste of having too many ducks on too small a body of water. I have read conflicting arguments about muscovies in relation to this problem. In some articles promoting these ducks I've see the fact that they eat algae listed as one of the benefits of keeping them. I've also read that they can add up to a pound a day of waste per duck into the water. This makes me skeptical if they are actually a net positive in terms of algae growth. It would seem to me that the additional nutrient load would outweigh the relatively smaller benefit you get from the birds eating algae. Does anyone know any concrete information about this? I'm wondering if I need to cut the number of birds I'm keeping on the lake down before I create more problems this summer.
