Análisis espacio temporal de la biología reproductiva y el reclutamiento del molusco bivalvo Anadara tuberculosa en la costa del Pacífico colombiano

Abstract: Análisis espacio temporal de la biología reproductiva y el reclutamiento del molusco bivalvo Anadara tuberculosa en la costa del Pacífico colombiano Abstract.-The reproductive cycle, recruitment and maturity size of the mangrove cockle Anadara tuberculosa was studied between August 2009 and August 2010 at the 4 departments of the Colombian Pacific coast. Biological samples were collected on three 50 m 2 plots of each region following the traditional method of capture. To determine the state of sexual developme… Show more

“…However, more research is needed on hermaphroditism in bivalves to improve our understanding of it (Breton et al 2018). It is necessary to understand sexuality in species such as A. tuberculosa, which in different populations has been classified as gonochoric (Cruz 1984), gonochoric with casual hermaphroditism (Pérez-Medina 2005) and protandric hermaphroditism (Lucero-Rincón et al 2013). These different sexualities have been defined according with different percentage of hermaphroditism, and some estimates of sex ratio and Table 1.…”

“…During the post-spawning phase and the onset of the resting phase of L. grandis (sub-phase 1), the presence of brown cells was noticeable, and their amount was reduced towards the end of the resting phase (sub-phases 2 and 3). Also, brown cells have been observed in the acini of ripe and partially spawned gonads of A. noae (Ghribi et al 2017), in ripe and spawning gonads of A. tuberculosa (Lucero-Rincón et al 2013) and in spawning and post-spawning gonads of A. similis (Manjarrés-Villamil et al 2013). These cells were named as brown secretion granules in A. tuberculosa and A. similis (Lucero-Rincón et al 2013, Manjarrés-Villamil et al 2013.…”

“…Flores (2010) Lucero-Rincón et al, 2013). En el Ecuador su reproducción parece tener un período de máxima actividad gonadal durante el período noviembre-febrero (Ayala et al, 2013;Flores et al, 2014).…”

“…En el Caribe colombiano se han determinado dos períodos de máximo desarrollo gonadal a saber son, junio-agosto y diciembre-marzo (Lucero-Rincón et al, 2013), sin embargo los autores señalan que el organismo se reproduce durante todo el año, con intensidades mayores en dos períodos. Este estudio histológico, es el primer reporte sobre desarrollo gonadal de esta especie en el Ecuador, los análisis histológicos macroscópicos y microscópicos no determinaron hermafroditismo en la especie, pero para esta especie se ha señalado casos de hermafroditismo (Lucero-Rincón et al, 2013). Los autores señalan un 3% de hermafroditismo, considerado protándrico, debido a las diferencias en proporción sexual entre hembras y machos (2,46:1) y a la diferencia de tallas entre sexos.…”
