The assessment of Newfoundland east and south coast Atlantic Herring (Clupea harengus) stock complexes considered data to the spring of 2014. A stock status index was provided for the Bonavista Bay-Trinity Bay (BBTB) and Fortune Bay (FB) stock areas where an annual research gillnet program provides an ongoing index of abundance; stock updates were provided for the White Bay-Notre Dame Bay (WBNDB) and St. Mary’s Bay-Placentia Bay (SMBPB) stock areas based on commercial samples, fisher observations and when applicable, abundance indices from adjacent stock areas. During the 2000s the spawning stock composition of most stock complexes has shifted toward a higher proportion of fall spawners, and spring spawning times have peaked later in the season and in early summer. In addition, there has been an increasing occurrence of herring during spring offshore surveys on the Grand Banks over the past decade. It is suspected that these changes are largely environmentally driven. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Bourne, C. Canada.
