Captive Double-Crested Cormorant Phalacrocorax Auritus Predation On Channel Catfish Ictalurus Punctatus Fingerlings And Its Influence On Single-Batch Cropping Production, Brian S. Dorr

Abstract.-We studied the effect of captive double-crested cormorant Phalacrocorax auritus predation on channel catfish Ictalurus punctatus inventories from research ponds with and without alternative prey during the years 1998-2000. In 1998, predation by two groups of captive cormorants on ponds without alternative prey produced inventory reductions relative to a control pond that were equivalent to 10.2 (516 g) and I 0.5 (608 g) catfish/bird per d. In 1999 and 2000 individual cormorants foraging on 0.02-ha pond halves for I 0 d (500 cormorant d/ha) stocked with both catfish and golden shiners Notemigonus crysoleucas produced inventory reductions at harvest (7.5 mo …
