Marc Chalupnicki Ross Abbett Avriel R Diaz Christopher C Nack James H. Johnson 2017 <p><span>Fish feeding ecology has been shown to vary over a 24-h period in terms of the prey consumed and feeding intensity. Consequently, in order to best determine the interspecific feeding associations within a fish community, examination of the diet at multiple times over a 24-h period is often necessary. We examined the diel feeding ecology of three fish species that were numerically dominant in a Lake Ontario embayment during summer. The diet of each of the three species, young-of-year Pumpkinseed </span><i><i>Lepomis gibbosus</i>,</i><span> Golden Shiner </span><i><i>Notemigonus crysoleucas</i>,</i><span> and Brook Silverside </span><i><i>Labidesthes sicculus</i>,</i><span> was distinct with no significant overlap in diet composition occurring within any of the 4-h time intervals. The diet composition of each species suggested that Brook Silverside were feeding at the surface (terrestrial invertebrates and aquatic surface dwelling hemipterans), whereas young-of-year Pumpkinseed (amphipods) and Golden Shiner (tipulids) were feeding on different benthic prey. Differences in feeding periodicity were most pronounced for young-of-year Pumpkinseed. Our findings provide valuable insights on interspecific feeding associations among these three fish species during summer in a Lake Ontario embayment.</span></p> application/pdf 10.3996/092016-JFWM-075 en Scientific Journals Feeding ecology of Brook Silverside, Golden Shiner, and Subyearling Pumpkinseed in a Lake Ontario embayment article
