2013 Standardized stock assessment survey

In 2013, eleven commercial longline vessels, seven Canadian and four U.S., were chartered by the International PaciÞc Halibut Commission for survey operations. During a combined 68 trips and 659 charter days, these vesselsÞshed 28 charter regions, covering habitat from northern California to the island of Attu in the Aleutian Islands, and north along the Bering Sea continental shelf edge. All 1,289 survey stations as well as eight rockÞsh stations planned for the 2013 survey season were completed. Of the survey stations, 1,279 (99.2%) were considered successful for stock assessment analysis. Approximately 602,191 pounds of halibut, 114,735 pounds of PaciÞc cod, and 45,650 pounds of rockÞsh were landed from the standardized survey stations. Compared to the 2012 survey, weight per unit effort (WPUE) increased in Regulatory Areas 2C and 4B.
