Description: Age, length, and sex data were collected from 4,377 halibut Hippoglossus stenolepis landed by sport anglers at Kodiak, Homer, Seward, and Valdez in 1992. Harvested halibut were 3-22 years old and were fully recruited to the sport fishery by ages 8 or 9. Ninety-eight percent of the harvested fish were 50-150 centimeters long. Mean weights (net) ranged from 7.2 kilograms (15.9 pounds) at Seward to 12.3 kilograms (27.1 pounds) at Kodiak. Age composition was significantly different among months only at Homer, while length composition differed among months at Homer, Seward, and Valdez. Female halibut made up 63% of the harvest at Seward, and 80%-85% of the harvest at other ports. Differences in age and size among ports corresponded with differences in sex composition. Halibut caught by chartered anglers at Homer and Seward were significantly longer than fish caught by private or military charter anglers. Geographic differences in size composition, sex composition, and length-at-age suggest there may be substocks of halibut that are subject to varying levels of exploitation.
