Evaluation of culture enclosures for the mangrove oyster Crassostrea rhizophorae suspended from raft and long-line systems

 We evaluated the growth and survival of the mangrove oyster Crassostrea rhizophorae (30 mm maximum length) reared in two suspended-culture systems (raft and long-line) using three types of enclosures (oyster enclosures, lantern nets and enclosures based on crates used to transport fish), a...

No significant differences were found in shell growth (length and mass) due to the system and enclosures used; however, raft-cultured oysters showed better tissue growth. At the end of the study, the oysters in lantern nets suspended from rafts obtained a tissue mass that was around 40% higher than that of the rest of the oysters cultured in the other enclosures. Significant differences in oyster survival were not observed for the raft and long-line systems used, but the cumulative survival at the end of the study was significantly higher for the oyster enclosures (52–56%) than for the lantern nets (36–39%) and fish crates (24–25%). We therefore recommend employing rafts and discarding the use of crate-type enclosures in the culture of C. rhizophorae in lagoon systems. Se evaluó el crecimiento y la supervivencia de la ostra de mangle Crassostrea rhizophorae (30 mm de longitud máxima) bajo cultivo en dos sistemas de flotación (balsa o batea y long line o línea madre) y tres tipos de cestos (cestos ostrícolas, linternas y canastas utilizadas para el trasporte de pescado), a una densidad de 750 ind m–2 en la Laguna La Restinga, Isla Margarita, Venezuela, durante seis meses. No existieron diferencias significativas en el crecimiento de la concha (longitud y masa) debido al sistema de cultivo o las cestos; sin embargo, las ostras cultivadas en el sistema de balsa mostraron mayor crecimiento del tejido, siendo las linternas donde los organismos alcanzaron mayor tejido al final del estudio, en un orden del 40% más alto que las ostras mantenidas en long line. En cuanto a la supervivencia las ostras no mostraron diferencias significativas en los sistemas utilizados, pero sí en las cestos, donde al final del estudio, la supervivencia acumulativa en las cestos ostrícolas, suspendidos en el long line o en las balsas (52–56%) fue significativamente superior a la de las linternas (36–39%) y éstas a las de canastas de pescado (24–25%). Se sugiere la utilización de balsas descartando el uso de cestos para el trasporte de pescado para el cultivo suspendido de C. rhizophorae en sistemas lagunares. 2006-06-23 2021-06-03T03:55:09Z 2021-06-03T03:55:09Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1056 10.7773/cm.v32i21.1056 https://hdl.handle.net/20.500.12930/7395 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1056/940 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 2 (2006); 331-337 Ciencias Marinas; Vol. 32 Núm. 2 (2006); 331-337 2395-9053 0185-3880
