Five biodegrabable twine types were investigated for potential use in the snow crab (Chinoecetes opilio) fishery that operates off Newfoundland and Labrador, Canada. The five twine types included 1) 2-ply Sisal, 2) 3-ply Cotton 60-threated, 3) 3-ply Cotton 72-thread, 4) 3-ply Cotton 96-thread and 5) 3-ply Hemp 40 strand. Each twine was deployed at sea for 124 days and their degradation rates over time were studied. The results indicate variability in twine degradation rates. The 3-ply cotton 96-thread twine was the best performing twine. Over the study period, this twine rapidly declined in breaking strength. The total reduction was 63% of the initial strength. In addition, there was a statistical relationship between breaking strength and soak time for three twin types 1) 2-ply Sisal, 2) 3-ply Cotton 60-thread and 3) 3-ply Hemp 40 strand. The 2-ply cotton 96-thread is now required for use by all fisheries in the province of Newfoundland and Labrador targeting snow crabs.
