Figure 4 
Radiocarbon (A* 4 C) values plotted against otolith-derived estimates 
of birth year for red bream (Beryx decadactylus) from reading 3. 
Horizontal bars represent the CV of the age estimate for each 
sample. The reference chronology is shown for haddock (Melano- 
grammus aeglefinus ) from Newfoundland (Campana, 1997). The 
best fit of Hamel et al.’s coupled-functions model to the otolith 
radiocarbon data is represented by the solid line for red bream 
and by the dashed line for haddock. 
ing condition, based on the presence of hy- 
drated oocytes and postovulatory follicles 
(Fig. 6C), were observed from June through 
September (Fig. 7A). There was one female 
for which reproductive stage could not be 
assigned because of poor quality of the his- 
tological sample. 
There were five males that were deter- 
mined to be mature, but reproductive stages 
could not be assigned even though spermato- 
zoa were detected because the samples were 
mostly duct tissue. Consequently, those five 
males could not be included in the analy- 
sis of spawning seasonality. For one addi- 
tional male there was not enough tissue to 
determine either a reproductive or maturity 
state, but it is unlikely that this male was 
immature, because it was neither one of the 
smallest nor one of the youngest males in 
the sample. Males in spawning condition, as 
indicated by the predominance of sperma- 
tozoa in ducts and lobules, were observed 
in all months for which male reproductive 
stages could be assigned. No resting males 
were present in the sample, but spent 
males were observed in July, August, No- 
vember, December, and January (Fig. 7B).
