The Struck-and-lost Factor in Alaskan Walrus Harvests, 1952-1972

Struck-and-lost rates during hunts for walruses, Odobenus rosmarus (Linnaeus), in Alaska from 1952 to 1972 did not vary from year to year. On average, 42% of the animals struck by bullets were lost (i.e., not retrieved). About 55% of the struck-and lost animals died immediately; the rest were wounde...
