Abstract

Information exchange should influence the ability of individual vessels to exploit fish aggregations, ultimately influencing fishing efficiency. We examined this hypothesis using data from Cuban and Russian vessels pursuing silver hake Merluccius bilinearis) on the Scotian Shelf from 1989 to 1993. Cuban fleet size and organization were similar among the years, while the Russian fleet decreased in size and became profit driven during this time. Changing fish abundances prevent direct comparisons of fishing success between years, but the relative performance of the nations provided a basis for interannual comparison of fishing success. The risk of gear damage during a trawl differed between the nations in the years studied. From 1989 to 1992, vessel performance improved after a move of over 20 nautical miles, but this trend was absent from the 1993 data. When movements were separated into potential tactics, moving to an area where other ships were fishing was most common, suggesting the use of public information. Russian vessels were significantly less mobile than Cubans immediately following the dissolution of the Soviet Union and their seasonal catch rates were typically lower. In the following year, Russians were more mobile than Cubans and their seasonal performance was comparable.
