fecundity

This could be achieved by standardizing either the larval rearing techniques and improving the adult diet for getting the maximum fecundity (Krishnamoorthy, 1984).

0 for fecundity rate, respectively in Damascus goats and it was concluded that progesterone impregnated intravaginal sponge treatment combined with GnRH and PGF2[alpha] injections might improve the success of estrous synchronization and fertility.

The fecundity was estimated by counting the number of mature ova (opaque and larger in size) from known weights of sub samples collected from the anterior, posterior and middle portions of the ovaries and calculating the total number of mature ova [26].

Fecundity 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.

Additionally to the absolute fecundity, relative fecundity (RF) has also been calculated following Hardisty (1964):

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.

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 indicate that pupal weight may also have an influence on fecundity (e.

In some cases, egg production is not linearly related to SSB, a situation that occurs when relative fecundity changes with age or size (e.

Our study estimated the fecundity of 39 female Alabama shad from the Apalachicola River, Florida.

This integrated approach investigated causal relationships among temperature, maternal size, fecundity, and egg quality, predicting a positive direct effect of temperature on egg quality and a concomitant positive effect of maternal size on fecundity.

Population structure and fecundity in Uca virens Salmon & Atsaides, 1968 (Decapoda: Ocypodidae) in southern Tamiahua Lagoon, Veracruz, Mexico

Studies in thorny round stingray Urotrygon chilensis and dwarf round stingray Urotrygon nana, show low fecundity and short gestation periods (Guzman 2006, Rubio 2009).
