The Halicarcinus planatus populations of the southwestern Atlantic Ocean show a highly variable sex ratio and a large size overlapping between females in the last immature instar (ADO) and mature (MAT) females. We hypothesized ...

Reproductive aspects and information on the effect of fishery activities over this species stock are scarce, despite the imperative need of effective protection and resource management programs. To support the possible ...

Oocyte maturation in vertebrates involves morphological, biochemical, and functional changes through which meiosis, previously arrested in Profase I, is resumed. Within these changes, germinal vesicle breakdown (GVBD) ...

The reproductive dynamics of a species is important information to have for the maintenance and reproduction of animals in captivity, for either commercial or conservation purposes. Steindachneridion melanodermatum is an ...

The aim of this study was to investigate the effects of sex on the net requirements of growth for Ca (NCag), P (NPg), Na (NNag), K (NKg), and Mg (NMgg) in Saanen goats from 5 to 45 kg BW, with or without consideration of ...

Requirements for growth in the different sexes remain poorly quantified in goats. The objective of this study was to develop equations for estimating net protein (NPG) and net energy (NEG) for growth in Saanen goats of ...
