The biggest US tuna firms filed a joint motion Friday to dismiss the antitrust lawsuits alleging the tuna companies conspired to fix the prices of packaged tuna.

Defendants StarKist Co., Dongwon Industries Co., Ltd., Bumble Bee Foods, LLC, Tri-Union Seafoods, LLC, Thai Union Group PCL, and Del Monte Corporation filed the motion asking the court to dismiss the lawsuits filed by grocery stores, grocery wholesalers, food distribution companies and other direct purchasers as well as individuals and commercial food preparers who indirectly purchased packaged tuna products from them.
