Factors which may have contributed to the relatively lower inshore cod catches in certain areas in 1985 and 1986 / by W. H. Lear. : Fs70-8/87-1E-PDF
"Inshore cod catches in NAFO Div. 2J3KL have been declining since 1982 inspite of an increasing total stock biomass of cod 4 years of age and older and also of the age 4-7 year-old-cod which form the bulk of the inshore cod catch and especially the cod trap catches. The below average temperatures in the cold intermediate layer of the Labrador Current may have acted as a thermal barrier discouraging cod from migrating inshore during 1985 but on the other hand the about normal temperatures in this layer in 1986 would not appear to have had an unusual effect on the inshore migration of cod in that year"--Abstract.
