Seal stomach contents were examined for whole prey and prey hard parts following the methods outlined in Murie and Lavigne (1985). Prey species were identified by comparing whole specimens or recovered hard parts to reference materials collected from NL waters and/or using published identification keys (Härkönen 1986, Scott and Scott 1988, Squires 1990, ICES 1997, Nozères and Bérubé 2003, Campana 2004, Frandsen and Zumholz 2004, Camphuysen and Henderson, 2017). This data is referenced spatially using DFO statistical unit areas:…
