ABSTRACT We studied the influence of environmental variables associated with three water depths (2, 6 and 10 m) on shell growth, soft tissues dry mass (STDM) and survival of the Caribbean winged oyster Pteria colymbus (Roding, 1798). chlorophyll-a (Chl-a), dissolved oxygen, particulate organic matter (POM) and temperature were studied at each depth. Oysters were placed in 135 plastic baskets with five individuals in each basket. Three baskets at each depth were chosen at monthly intervals for measurements of biometric parameters, biofouling, and survival. At the end of the study, dry mass of the individuals grown at 10 m was significantly lower (Kruskal-Wallis non-parametric test KW, P &lt; 0.05) with the highest values of STDM corresponding to oysters...

ABSTRACT 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, BBO and 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...
