Settlement and Early Nursery of JuvenileAnadara grandis(Pelecypoda: Arcidae) Under Different Conditions at the Hatchery and Ponds

Early life cycle description and effects of microalgal diets on larval and post‐larval development of the mangrove cockleAnadara tuberculosa(Sowerby, 1833)

“…Compared with the larval phases, the longer 30-day metamorphosis phase (from pediveliger larvae to spat) requires further research to achieve better settlement rates. However, this 30-day period is similar to that reported for species of the same genus, such as A. grandis larvae, which require 35 days to complete metamorphosis (Reynoso-Granados et al, 2012). Other bivalves even require more time such as S. limbatus which takes 60-90 days to metamorphize (Loor et al, 2016).…”

“…On a global scale, other species of the genus Anadara have been successfully reproduced in captivity. These include A. granosa (Muthiah et al, 1992), A. trapezia (Nell et al, 1994), A. antiquate (Pu et al, 2012) and A. grandis (Reynoso-Granados et al, 2012). In our study, successful spawning in the laboratory has only been demonstrated in the months between October and March, when the species is at its reproductive peak (Ayala Montano, 2011).…”

Shell dimension-weight relationships in the blood cockle Larkinia grandis (Bivalvia: Arcidae) on the southeastern coast of the Gulf of California

“…The relationships between shell dimensions and body weight are a useful tool for accurately interpreting the development and relative growth of bivalves. Previous research on L. grandis has provided information on age and growth (Cruz 1986), size and sexual maturity (Cruz 1987), and reproduction in the wild (Borda and Cruz 2004) and in cultures (Reynoso-Granados et al 2012). However, most of this information has been documented for populations outside the Gulf of California.…”

“…Las relaciones entre las dimensiones de la concha y el peso corporal son una herramienta útil para interpretar con precisión el desarrollo y el crecimiento relativo de los bivalvos. Investigaciones anteriores sobre L. grandis han proporcionado información sobre la edad y el crecimiento (Cruz 1986), el tamaño y la madurez sexual (Cruz 1987) y la reproducción en la naturaleza (Borda y Cruz 2004) y en cultivos (Reynoso-Granados et al 2012). Sin embargo, la mayor parte de esta información ha sido documentada para poblaciones fuera del golfo de California.…”
