The snow is almost all gone around here, and soon i will have access to a lot of small fish in the river all around here (i live on a big island in the middle of the St-Lawrence, Quebec). I will be able to catch them quite easily with a small fish net. Can these small fish be a risk for my water snake ? The water are quite clean, its not the pollution that bother me, but the risk of parasite. Is the freshness of these fish and the fact that they are well feed is more beneficial then the risk of parasite ?
