Can I grow yabbies and fish together in the same dam?
Yes you can, however, all fish do eat yabbies so the number of yabbies produced by the dam will be lower with fish in it than no fish. The advantage is that the fish will grow faster with the yabbies as an extra food source. Silver Perch only have small mouths and only eat small food items so any yabby over 5 gram in size is usually too big for them to eat. Large numbers of yabbies are easily produced in Silver Perch dams. Both Bass and Yellowbelly have large mouths and even quite large yabbies are good food. Yabbies in these dams will build up populations in the shallow water around the edges away from the fish. As the yabby population increases the young ones will move into the deeper water looking for living space and be consumed.
