Robert Allen Dorrier, 45, was found guilty of theft after two watermen testified that on Aug. 7, 2015, they watched as the defendant dumped crabs from commercial pots onto the deck of his skiff, threw the pots overboard without closing them and sped off.
An officer intercepted Dorrier and charged him.
Dorrier also was found guilty of two counts of disrupting lawful fishing activity and two counts of removing fish, nets or gear of another.
Dorrier was taken into custody after his trial.
