摘要

Little is known about the marine life-history phase of the anadromous sea lamprey Petromyzon marinus. The most widely accepted hypothesis suggests a hematophagous feeding phase of 2.5 yr. We captured and tagged (individually numbered T-bar anchor tags) 408 postmeta-morphic sea lampreys during the onset of the hematophagous feeding phase in the River Ulla and its estuary (NW Spain). One marked sea lamprey was recaptured during its spawning migration (total length: 895 mm, weight: 1218 g). This individual had been marked 13.5 mo before recapture, and had measured 218 mm and 20 g. Our results suggest that at least a portion of the sea lamprey population can reach adult size in 1 yr of hematophagous feeding. This further suggests a period between completion of metamorphosis and reproduction of 1.5 yr (18 to 20 mo).
