“…El desarrollo de métodos óptimos de cultivo para maximizar el crecimiento y la supervivencia de las ostras perlíferas juveniles ha sido importante para reducir el tiempo que se requiere para alcanzar un tamaño operable para la producción de perlas (Millione y Southgate, 2011). En el caso de la P. sterna, una especie emparentada con P. colymbus, algunos autores han determinado un crecimiento y supervivencia diferenciales en individuos ubicados en distintos tipos de recinto en cultivos suspendidos (Millione y Southgate, 2011) o entre el cultivo suspendido y el cultivo en el fondo del mar (Gaytán-Mondragón et al, 1993). Por enclosure device plays an important role on the cultivation of the species.…”

“…Por enclosure device plays an important role on the cultivation of the species. Millione and Southgate (2011) showed that site selection and culture unit are important parameters for optimizing the growth and survival of P. penguin during its culture's nursery phase. The enclosure system also exerts an influence on the quality of half pearls (mabés) produced by P. sterna (Ruiz-Rubio et al, 2006), as no significant differences occurred in the growth of the oysters held in plastic cages and pocket nets, but a greater yield of commercial quality pearls occurred in those grown in plastic cages.…”

The performance of the winged pearl oyster Pteria colymbus juveniles under suspended culture conditions was evaluate, including five culture methods and two seasons: upwelling and non-upwelling. Culture methods comprised enclosures confining the oysters: BTBC, BBOand BTO; and two other unconfined-oyster: OFOB and FNS. The initial shell height of the oysters ranged between 31–35 mm in both seasons. The increase in shell size and dry mass of soft tissues showed significant differences between seasons. Greatest growth occurred with the OFOB and FNS unconfined methods. The ANOVA II analysis showed significant differences between the variables obtained in both stations and culture methods. Principal Component Analysis showed that the interactions between the variables: temperature (inverse relationship), and UI, chl-a and POM (direct relationship) explained 89 % of the variability of the growth of the oysters. Given the low survival rates, attributed to the presence of predators within the closed enclosures and the higher growth seen in the culture methods without confinement, we recommend using the FNS and OFOB methods, taking advantage of the byssus produced by P. colymbus.
