description The optimal tide height at which the intertidal oyster bed system (IOBS) should be installed to cultivate Crassostrea corteziensis in Boca de Camichín (BC), Nayarit, Mexico, during the intermediate grow-out stage (39.3–60.2 mm in shell length) was determined. Temperature, salinity, chlorophyll a (Chla), and turbidity were recorded 3 times a day. A trophic state index (TSI) was calculated with Chla and turbidity data. Three treatments corresponding to tide levels were tested: (1) high level (14 cm above mean sea level [MSL], emersion time [ET] = 56.4% of the total duration of the experiment), (2) intermediate level (MSL, ET = 48.6%), and (3) low level (41 cm below MSL, ET = 32.1%). Gross growth rates and absolute and relative monthly growth rates were calculated to identify periods with highest growth relative to environmental conditions. Finally, the effect of the treatments on the dimensions and weight of the oysters was studied. The results indicate that BC water was mesotrophic in April–June and eutrophic in July–August. The low tide level was the best for IOBS operation, with growth rates of 0.15, 0.10, and 0.07 mm·d–1 in shell length, width, and thickness, respectively, and 0.204 g·d–1 wet weight. Cumulative mortality was lower in the low (18.5%) and intermediate (16.4%) treatments. Shell thickness was significant reduced (P < 0.05) in the high treatment and total wet weight was reduced in the high and intermediate treatments. The results of this study offer a viable and different alternative to the cultivation of C. corteziensis in strings that is currently carried out in Boca de Camichín, Nayarit, Mexico.

Se determinó la altura de marea óptima a la que se debería instalar el sistema de camas ostrícolas intermareales (SCOI), para cultivar Crassostrea corteziensis en Boca de Camichín (BC), Nayarit, México, durante la etapa de preengorda (39.3-60.2 mm de longitud). La temperatura, salinidad, clorofila a (Cla) y turbiedad se registraron 3 veces al día. Se calculó un índice de estado trófico (IET) con datos de Cla y de turbiedad. Se probaron 3 tratamientos correspondientes a los niveles de marea: (1) nivel alto (14 cm por encima del nivel medio del mar [NMM], tiempo de emersión [TE] = 56.4% de la duración total del experimento), (2) nivel intermedio (NMM, TE = 48.6%) y (3) nivel bajo (41 cm por debajo del NMM, TE = 32.1%). Se calcularon las tasas de crecimiento bruto y las tasas de crecimiento mensual absoluto y relativo para identificar los periodos con mayor crecimiento en relación con las condiciones ambientales. Finalmente, se estudió el efecto de los tratamientos sobre las dimensiones y el peso de la concha. Los resultados indican que el agua de BC fue mesotrófica en abril-junio y eutrófica en julio-agosto. El nivel de marea bajo fue el mejor para la operación del SCOI, con tasas de crecimiento de 0.15, 0.10 y 0.07 mm·d–1 en longitud, anchura y espesor de la concha, respectivamente, y 0.204 g·d–1 de peso húmedo. La mortalidad acumulada fue más baja en los tratamientos bajo (18.5%) e intermedio (16.4%). Se observó una reducción significativa (P < 0.05) en el grosor de la concha en el nivel alto y una reducción del peso total húmedo en los tratamientos alto e intermedio. Los resultados del presente estudio ofrecen una alternativa viable y diferente al cultivo de C. corteziensis en sartas que actualmente se realiza en Boca de Camichín, Nayarit, México.
