Age-stage specific fecundity
(fxj) explains mean number of eggs laid per adult female at age x and stage j per day (adult female of M.
To determine fecundity
, the total egg mass of the female was detached carefully with the aid of dissection tweezers.
Relationship between total length and body weight, total length and fecundity
, body weight and gonado-somatic index, body weight and fecundity
were determined using Pearson's correlation.
Three estimates of fecundity
were calculated: 1) by counting the number of oocytes in the largest group of oocytes in the ovaries, which were presumed to be the next litter; 2) by using total embryo count (candled and free-living embryos), and 3) by using counts of only free-living embryos.
models were first run with continuous urinary concentrations to assess potential linear associations between urinary chemicals and fecundity
then in quartiles to assess nonlinear relationships.
was estimated from gravid females collected from the Umiam River throughout the study period, and was determined using the gravimetric method (Babiker & Ibrahim, 1979).
Density dependence of walleye maturity and fecundity
in Big Crooked Lake, Wisconsin, 1997-2003.
Total 24 goats were confirmed as non pregnant through ultrasonography and were equally divided into three groups for undertaking fecundity
The diets contained artificial ingredients significantly influenced oviposition and post-oviposition periods and fecundity
of females [4,5].
HUMIDITY EXPERIMENTS TO DETERMINE FECUNDITY
AND EGG INCUBATION
KEY WORDS: Cancer pagurus, Crustacea, reproductive ecology, fecundity

Relationship between fecundity
and fork length, weight, and age were calculated using equations LogFL = Loga + b x LogL, FW = a + b x W, and FA = a + b x A, respectively (Avsar, 2005).
eridania (Montezano et al., 2013) also demonstrated that multiple couples led to a greater number of copulations, thus increasing fecundity
Egg skeins were collected from 18 females to assess fecundity
. The egg skeins (n = 18) were cut open under a dissecting scope and eggs were individually counted and verified by a second counter to insure accuracy.
Our study estimated the fecundity
of 39 female Alabama shad from the Apalachicola River, Florida.
