Walsh, S.J. 1984. Relative Efficiency of two Bottom Trawls in Catching Juvenile and Commercial-sized Flatfishes in the Gulf of St. Lawrence. J. Northw. Atl. Fish. Sci. 5(2): 181-188. https://doi.org/10.2960/J.v5.a22
Abstract
The relative efficiencies of a No.36 Yankee shrimp trawl and a No. 41.5 Yankee otter trawl in catching three species of flatfishes (witch flounder, American plaice and Greenland halibut) were compared from data collected during research-vessel surveys of the northeastern Gulf of St. Lawrence. The shrimp trawl outfished the otter trawl in catching juveniles ( <= 30 cm) flatfishes was evaluated from a series of replicate tows. Marked increases in the catches with the use of a tickler chain.
