The fish community of Grenadier Pond has undergone considerable change over the years. With the connection to the lake gone, the fish are locked into the pond and rely on it for all of their lifecycle requirements. About 12 species now occur in Grenadier Pond, including small numbers of top predators such as bass, and more abundant smaller fish such as pumpkinseed and bluegill.
1 Predators that eat other fish
2 Non-native species

NOTE: The list of species shown above may be overlooking bottom-feeding fish (such as gobi, a European species) which would not be detected by the regular monitoring techniques used by the TRCA.
