BRUNEAU, B., F. GRÉGOIRE, 2011. Spatial distribution study of Atlantic Mackerel (Scomber scombrus) and Capelin (Mallotus villosus) abundance data from winter groundfish surveys in NAFO Divisions 4VW using generalized additive models. Can. Tech. Rep. Fish. Aquat. Sci., 2930, 27 p .
Generalized additive models (GAM) have been studied to describe the possible relationship between the geographic position (km), tow depths (m), bottom water temperature (°C) and abundance (log number / tow + 0.1) of Atlantic mackerel (Scomber scombrus) and capelin (Mallotus villosus) caught in a series of groundfish surveys conducted on the Scotian Shelf between 1994 and 2003. The selected models were used to determine the factors with a significant influence on Atlantic mackerel and capelin catches. These models also helped describe the thermal preferences of these two species. However, no abundance prediction was made because of the high number of tows without any catches.
