Ten species of microalgae were tested for ingestion and digestion in Pteria sterna larvae using epifluorescence microscopy to choose an appropriate diet. An experiment was conducted using 2, 4, 5 (straight-hinge) 10 and 22 (umbo stage) day old larvae.

Abstract This study generated baseline information relative to overall performance of the winged pearl oyster Pteria sterna implanted at two groups (small and large) for half-pearl (mabe) production. This is a suitable technology to optimize the pearl production in the tropical coasts of Ecuador.

This study reports the survival, hemocyte count and physiological response indicators of pearl oysters Pteria sterna and Pinctada mazatlanica seeded with allografts and xenografts for pearl culture. Two treatments of oysters receiving an allograft (both donor and host were Pt. sterna) or a xenograft (donor was Pt. sterna and host was P.

Abstract This study aims to evaluate the influence of nucleus size and culture duration on the nacre deposition rates of half pearls produced by the winged oyster P. sterna. For the nucleus size study, three different sizes of hemispherical implants were tested; small (9 mm), medium (11 mm) and large (14 mm), each of these treatments was assigned ...

The rainbow pearl oyster Pteria sterna is distributed along the Mexican Pacific coasts and Gulf of Baja California, where it represents a great economic potential. Five sampled populations collected in Baja California were used to screen two mitochondrial DNA genes that have proven useful in population genetics studies of several other bivalve species.

Two groups of 96 winged pearl oysters, Pteria sterna, with mean (± S.D.) dorso-ventral shell height (DVM) of 75.0 ± 6.0 mm, were used to evaluate the effect of two culture methods (pocket nets and plastic cages) on the quality of half-pearls (mabe) produced from them over a period of 9 months.

ABSTRACT Using a combination of stereological and calorimetric methods, we studied reproductive effort of Pacific winged pearl oyster Pleria sterna during an annual cycle in Bahia de La Paz, B.C.S., Mexico. The relationship between changes in the volumetric fraction of germinal and somatic tissues (gonad, digestive gland, adductor muscle, and mantle ...
