Age-specific
fecundity (mx) was 0.132, 0.304 and 0.333 females per female per day at age of 26th day, 20th day and 15th day with age specific survival (lx) was 0.53, 0.46 and 0.24 days at 24 +- 0.5 AdegC, 27 +- 0.5 AdegC and 32 +- 4 AdegC, respectively.
A linear regression model was used to represent the relationship between
fecundity and female size (TL) for Stage I and III.
The mean
fecundity and mean relative
fecundity were 14892.31 [+ or -] 2854.20 (3257.14-76377.36) and 49.82 [+ or -] 9.87 (6.27-21.85) respectively.
Fecundity was estimated by the number of developing embryos in the uteri and the number of developing oocytes in the ovaries.
When partners were modeled individually, no associations were observed between ln-transformed chemical concentrations and couple
fecundity even after adjustment with the exception of the biomarker 4-HB (Table 3).
Additionally to the absolute
fecundity, relative
fecundity (RF) has also been calculated following Hardisty (1964):
Under hormonal protocol of
fecundity trial seven goats (87.50%) out of eight goats showed induced estrus.
Daily observation were carried out to know the
fecundity, the duration in the days of pre-oviposition, oviposition and post-oviposition periods, the egg hatching percentage, the larval development duration, pupal duration, survival and mortality on different artificial diets.
Therefore,
fecundity rather than egg output was measured (Munger 1942; Larentzaki et al.
Understanding reproductive patterns, the size at maturity, the behavior of ovigerous females,
fecundity, and egg/ larval quality all contribute to estimates of the turnover capacity of natural populations.
The
fecundity ranged from 4365 to 65982, and mean
fecundity was calculated 25349.
eridania indicate that pupal weight may also have an influence on
fecundity (e.g.
