OPINION

The Fishing Company of Alaska, William McGill, and Richard Joseph appeal from the district court’s order granting summary judgment for the United States. The appellants challenge the regulations establishing the Vessel Incentive Program (“VIP”), a fishery management plan created by the North Pacific Fishery Management Council (“The Council”) as part of its responsibility under the Magnuson Ste*1046vens Fishery Conservation and Management Act, 16 U.S.C. §§ 1801-1883. See 16 U.S.C. § 1852. The appellants also challenge the fine imposed by the National Oceanic and Atmospheric Administration for exceeding the standards for halibut bycatch set by the agency under the VIP.

The appellants also contend that the district court should have supplemented the administrative record with statements from a 2001 meeting of the Council discussing the effectiveness of the VIP. Because the appellants failed to make the “strong showing of bad faith or improper behavior” that may justify an inquiry “into the thought processes of administrative de-cisionmakers,” Public Power Council v. Johnson, 674 F.2d 791, 795 (9th Cir. 1982), we conclude that the district court did not abuse its discretion in declining to supplement the record.

We affirm the decision of the district court for the reasons well articulated in its opinion, reported at Fishing Co. of Alaska v. United States, 195 F.Supp.2d 1239 (W.D.Wash. 2002).

AFFIRMED.
