Since the time of the study of Sonina (1973) the NEA haddock
has undergone tremendous changes in population size. While the
population size was estimated to be quite large in the early 1970s
it fell to a historic low in the mid 1980s. Since then the population
size has fluctuated somewhat, but overall steadily increased with
an estimated spawning stock biomass of
∼200,000 metric tonnes in
2008 (ICES, 2011) (Fig. 1). Due to the high fishing mortalities on NEA
haddock, which might impose an evolutionary response in reproductive
investment similar to that observed in North Sea haddock
(Wright et al., 2011), it is of considerable merit to re-examine the
fecundity dynamics in this northern stock of haddock.
