Net fecundity $(\text{eggs})={\displaystyle \sum _{\mathrm{x}=\mathrm{\alpha }}^{\mathrm{\beta }}{\mathrm{l}}_{\mathrm{x}}{\mathrm{M}}_{\mathrm{x}}}$, Gross fecundity $(\text{eggs})=({\displaystyle \sum _{\mathrm{x}=\mathrm{\alpha }}^{\mathrm{\beta }}{\mathrm{M}}_{\mathrm{x}})}$, x = age interval in days, a = age at start of reproduction, b = age at end of reproduction, l_x = Proportion of individuals surviving to age x, M_x = Total numbers of eggs laid by the average female at age x (Carey, 1993)
