Distribution and abundance of Atlantic cod from an acoustic survey of Bonavista Bay - Trinity Bay, Newfoundland during the fall of 1999 / John P. Wheeler. : Fs70-1/2000-072E-PDF

An acoustic survey was conducted during the fall of 1999 in the coastal waters of Bonavista Bay - Trinity Bay, Newfoundland. The survey area included water depths from the coastline to the 120 m contour. Echo integration along a series of parallel transects within the survey area provided distributional information, densities and a biomass estimate of Atlantic cod. Comparisons were made with a similar survey conducted in the fall of 1996. The distribution of cod differed between the two surveys. A substantial aggregation of cod was detected in Smith Sound, Trinity Bay during the current survey which was not evident in 1996. It was concluded that there were no other large aggregations of cod, comparable to that in Smith Sound, within the survey area during the fall of 1999.
