MIm,sure you know this but here goes,(fish or shellfish may be cleaned or portioned while in the field with the following exceptions:It is unlawful for a angler to retain proof of compliance with species,size,number,weight,sex or wild or hatchery origin restriction,if such restrictions apply,until the angler is ashore and has finished fishing for the day.)This is from WDFW pamphlet.So i would clean the fish and on the way home stop at a gas station and toss the rest. Might not be right but you have to live somewhere.
