dc.description.abstract Abstract: Juveniles of the Caribbean scallops Argopecten nucleus and Nodipecten nodosus were suspended in pearl nets at densities of 25%, 30% and 50% coverage of the bottom of the net (BC) during days. Additionally, adults of A. nucleus (>35 mm) were placed in lantern nets at densities of 40%, 50% and 65% BC during days. Stocking density affected the growth of animals, with higher growth rates obtained at the lower densities. Although the survival of the two scallops was not influenced at the densities studied, the 15‐day net changes, and culture in water of <28 °C produced better survival of A. nucleus and N. nodosus respectively. Predators of the families Cymatiidae, Grapsidae, Portunidae, Majidae and Xanthidae were found in the culture nets of juvenile A. nucleus, but during the adult phase they were absent. Predators exhibited a dense‐independent behaviour in relation to scallops. There was not any association between predator frequency and survival of A. nucleus. <br /> Resumen: Los juveniles del núcleo de vieiras del Caribe Argopecten y Nodipecten nodosus se suspendieron en redes de perlas a densidades del 25%, 30% y 50% de cobertura del fondo de la red (BC) durante días. Además, los adultos de A. nucleus (> 35 mm) se colocaron en redes de linternas a densidades del 40%, 50% y 65% ​​aC durante días. La densidad de población afectó el crecimiento de los animales, con tasas de crecimiento más altas obtenidas en las densidades más bajas. Aunque la supervivencia de las dos vieiras no se vio afectada por las densidades estudiadas, los cambios netos de 15 días y el cultivo en agua a <28 ° C produjeron una mejor supervivencia de A. nucleus y N. nodosusrespectivamente. Se encontraron depredadores de las familias Cymatiidae, Grapsidae, Portunidae, Majidae y Xanthidae en las redes de cultivo del núcleo A. juvenil , pero durante la fase adulta estuvieron ausentes. Los depredadores exhibieron un comportamiento denso-independiente en relación con las vieiras. No hubo asociación entre la frecuencia de depredadores y la supervivencia de A. núcleo spa
