, 1991 Se determino la influencia que tienen la temperatura y la concentración de alimento en el crecimiento de las ostra perlea Pteria sterna. Se utilizaron temperaturas de 20, 25 y 30 °C y concentraciones de alimento de 2, 4 2 y 8 % del peso seco calculado de los organismos. Como fuente de alimento se empleo la microalga Chatoceros sp.

Abstract The reproductive cycle of a wild population of the oyster pearl Pteria sterna living in the Ojo de Liebre lagoon was analyzed from February 2001 to February 2002. The gonadic development was studied both qualitatively (through histological analysis) and quantitatively (through an analysis of the percent follicular area). P.

Release density influences restocking success in the winged pearl oyster Pteria sterna
Ocean & Coastal Management, 2019Abstract A restocking experiment was conducted to determine the influence of release density on growth, survival with protection (natural), and survival without protection (by predation) in the winged pearl oyster Pteria sterna. Adult oysters were directly placed over the sea floor at 10 m depth in triplicate, 3 × 3 m parcels at densities of 5, 10 ...

Ensuring supplies of pearl oyster spat for commercial grafting operations in Mexico is an ongoing problem. This has refocused research toward improving hatchery propagation protocols. Since gender plays an important role in the physiology of bivalves, we studied the use of fatty acids in the gonad and digestive gland of male and female winged pearl ...

Mollusk biomineralization is a process controlled by a complex interplay of proteins, ions and external regulators. In spite of several studies, there is a lack of knowledge of who (molecules involved), how (mechanism) and why (evolution and adaptation) mollusk are designed as we know them.

Abstract The aim of the present study was to determine the spatial and temporal spatfall of the winged pearl oyster Pteria sterna in three different synthetic collectors (green mesh bags + mesh fence and mosquito net), deployed at three depths (2, 4 and 6 m).

Abstract This study expands on the criteria for selecting relaxants used in commercial production of pearls, based on the hypothesis that relaxation, before acting at a cellular level, is a stressor that triggers a battery of physiological responses.

Abstract The winged pearl oyster Pteria sterna sustains the Mexican pearl industry, but recent problems ensuring the provision of spat for grafting operations have refocused research toward gonad maturation and hatchery production of spat. We used several indicators (morpho-physiological indices, histology, histochemistry, proximal and fatty acid ...
