Wheeler, J.P., and Winters, G.H. 1984. Migrations and Stock Relationships of East and Southeast Newfoundland Herring (Clupea harengus) as shown by Tagging Studies. J. Northw. Atl. Fish. Sci. 5(2): 121-129. https://doi.org/10.2960/J.v5.a17
Abstract
From the tagging of Atlantic herring in different seasons at 23 localities along the east and southeast coasts of Newfoundland during 1974-81, the tag recoveries indicated substantial intermingling of the local populations of the different bays. This intermingling is mainly due to northward feeding migrations in summer and southward migrations in autumn to over-wintering areas. Movement to spawning grounds occurs in the spring, at which time the populations of the various bays tend to be very discrete. However, the relationships of the populations outside the spawning season are dynamic, with the degree of intermixing being partially dependent on population size. It is concluded that the fisheries for herring along the east and southeast coasts of Newfoundland outside the spawning season could conveniently be managed as four stock complexes in the following areas: White Bay-Notre Dame Bay, Bonavista Bay-Trinity Bay, Conception Bay-Southeast Avalon, and St. Mary's Bay-Placentia Bay.
