Mature females (stage 4 of vitellogenesis) from CW presented significantly
lower GSI (p=0.04) compared to those from the BFT treatment
with, respectively, 6.56% ± 0.58% (n = 9) and 7.28% ± 0.56% (n =9).
This corresponded to a significantly lower (p = 0.04) number of eggs
laid per spawn by females from CW(175,726 ω±52,976 ω) compared
to females from the BFT treatment (202,325 ω ± 60,118 ω). Finally
broodstock from CW produced a lower total cumulative number of
eggs (−72%) compared to those from the BFT treatment (p = 0.04).
The total numbers of eggs produced over the trial period based on 75
females from each treatment are presented in Table 4.
