Description

  • The red abalone Haliotis rufescens is one of the most important species for aquaculture in Baja California, México. there is an increasing interest in studying aspects such as reproduction, thermoregulation and endocrinology. The longitudinal cross-section of the abalone shell (H. rufescens) shows two types of microstructure: an outer prismatic layer (calcite); and an inner nacreous layer (aragonite). The two forms of CaCO3, calcite (rhombohedral) and aragonite (orthorhombic) constitute the inorganic component of this ceramic/organic composite (95 wt% ceramic, 5 wt% organic material). Currently, thereis anapparent skewed sex ratio, where males are changing to females, and this affects broodstock availability to obtain larvae at commercial scale. In red abalone, full sex differentiation usually occurs at around 50 mm of shell length based on histological analysis. However, gonadal primordia have been found in females with 26 mm of shell length. At the same time, there is an interest in improving the rate of growth of red abalone through neuropeptide characterization. [1] [2].
