Sereda and Hudson (2010) are commenting on a carcassbound phosphorus (P) flux estimate reported in an article by Chidami and Amyot (2008). This article mainly presents in situ experimental evidence on the factors affecting fish degradation in lakes. To place these field results in a biogeochemical context, Chidami and Amyot (2008) concluded their paper by presenting an estimate of some selected phosphorus fluxes in one of the studied lakes. For P fluxes related to carcass fall, we used estimates of white sucker (Catostomus commersoni) mortality rates from Verdon (1976) because it was the only full data set available on fish population dynamics in one of the studied lakes. In their comment, Sereda and Hudson (2010) consider that the fish mortality rates are anomalous, that the reported P fluxes due to carcass fall are too high, that other fluxes should have been considered, and that bone decomposition was not monitored. In the following, we will address each of these points.
