(English) Use of magnetic tags to mark tiger muskellunge

Désolé, cet article est seulement disponible en Anglais Canadien.

Tiger muskellunge (Esox masquinongy × E. lucius) were marked with magnetic wire tags in the cheek musculature, dorsal fin, and anal fin and later examined with a magnetic wire wand detector in an effort to determine the viability of using tag location as a means of identifying groups of fish. Tag retention was 88.3% in the dorsal fin after 185 d, 99.4% in the cheek after 185 d, and 99.0% in the anal fin after 72 d. Varying tag location appears to be a useful way to identify groups of tiger muskellunge.
