Analysis of Atlantic cod, Greenland halibut, redfish, and skate stomach contents from the 2018 NSRF-DFO summer shrimp survey in Hudson Strait, Davis Strait and Labrador Sea / by Hannah Polaczek, Sheila... : Fs97-13/1338E-PDF
"The stomach contents of Atlantic Cod (Gadus morhua), Greenland Halibut (Reinhardtius hippoglossoides), redfishes (unidentifiable Sebastes sp.), and skates (unidentifiable Rajidae) sampled during the 2018 Northern Shrimp Research Foundation and Fisheries and Oceans Canada (NSRF-DFO) summer shrimp survey in the Eastern Assessment Zone (EAZ), Western Assessment Zone (WAZ), and Shrimp Fishing Area 4 (SFA 4) were analyzed. This work was done to help determine the potential predation pressure of these fishes on the regions' populations of Northern Shrimp (Pandalus borealis) and Striped Shrimp (Pandalus montagui) in the context of stock assessment for the commercial Northern Shrimp fishery. The results of these analyses found the relative contribution by percent weight (%W) and percent number (%N) of Pandalid prey in comparison to all other taxonomic categories of prey to be highest within the stomachs of Atlantic Cod (n = 27), with %W and %N values of 87.1% and 92.7%, respectively. The %W values were 23.4% and 14.0%, while the %N values were 15.5% and 30.6% for the stomachs of Greenland Halibut (n = 633) and skates (n = 168), respectively. There was no Pandalid prey observed in redfish stomachs (n = 186)"--Abstract, page vi.
