“…The genetic diversity of N. magellanica in each locality was relatively high and did not vary considerably among sampling sites (mean P% = 78.48; mean I = 0.36). The Shannon's diversity index values are comparable to the ones obtained in two Portuguese localities of the commercial pullet carpet shell Venerupis senegalensis (I = 0.339-0.361; Joaquim et al, 2010) using RAPD dominant markers and are much higher than those reported for two barnacle species using ISSRs (I of Chthamalus stellatus = 0.147-0.222; I of Tesseropora atlantica = 0.111-0.190; Pannacciulli et al, 2009). The authors discussed these genetic variability values in relation to the population size and lifespan of the larval stage, being higher in large populations with extensive larval dispersal than in small populations with short larval lifespan.…”

“…Aveiro is a shallow lagoon system with high tidal flow that allows a large water renovation. This may promote larval drift to the coastal waters (Joaquim et al 2010) and be responsible for larvae dispersal, preventing genetic differentiation. Although Ferrol is also located northwest of the Iberian Peninsula, it showed significant differences to all other four Iberian localities analyzed but Corcubión.…”

Genetic diversity and population differentiation in the cockle Cerastoderma edule estimated by microsatellite markers

et al. 2012

The edible cockle Cerastoderma edule is a marine bivalve commercially fished in several European countries that have lately suffered a significant decrease in production. Despite its commercial importance, genetic studies in this species are scarce. In this work, genetic diversity and population differentiation of C. edule has been assessed using 11 microsatellite markers in eight locations from the European Atlantic coast. All localities showed similar observed and expected heterozygosity values, but displayed differences in allelic richness, with lowest values obtained for localities situated farther north. Global Fst value revealed the existence of significant genetic structure; all but one locality from the Iberian Peninsula were genetically homogeneous, while more remote localities from France, The Netherlands, and Scotland were significantly different from all other localities. A combined effect of isolation by distance and the existence of barriers that limit gene flow may explain the differentiation observed.

“…Besides the genetic plasticity and genetic similarity of the two populations reported by Joaquim et al(2010), and which make the Ria de Aveiro V. senegalensis population a genetically viable broodstock for intensive hatchery production of juveniles, the extended spawning period of this V. senegalensis population has interesting implications for the implementation of profitable aquaculture. This extended natural spawning period implies that manipulation of broodstock in terms of conditioning, which should be initiated in late summer, would be relatively easy.…”

SUMMARY: The present study characterizes the reproductive cycle of Venerupis senegalensis (=V. pullastra) from Ria de Aveiro (Portugal) as well as its nutrient storage and exploitation strategy. The reproductive cycle followed a seasonal cycle that correlated negatively with sea surface temperature, and comprised a ripe stage in winter followed by a spawning period that began in late winter and ended in the early summer. This extended spawning may be an advantageous strategy for the species because it ensures a continuous supply of settlers. Gametogenesis began in late summer/early autumn and intensified with the decrease in temperature during autumn. The condition index increased even during the spawning period, which indicates that there is rapid recovery and that reserves are accumulated during late summer and used later in the gametogenic process. Proteins did not contribute significantly to gametogenesis and the glycogen pattern is typical of conservative species, since gametogenesis depends largely on the amount of glycogen stored. The lipid storage and utilization cycle showed that gametogenesis took place in autumn/winter and that energy reserves were accumulated in summer.Keywords: pullet carpet shell, Venerupis senegalensis, biochemical composition, condition index, reproductive cycle.RESUMEN: Actividad reproductiva y composición bioquímica de la almeja babosa Venerupis senegalensis (Gmelin, 1791) (Mollusca: Bivalvia) de la Ría de Aveiro (costa noroeste de Portugal). -El presente estudio caracteriza el ciclo reproductivo de Venerupis senegalensis (= V. pullastra) en la Ría de Aveiro (Portugal) así como su estrategia de almacenamiento y explotación de los nutrientes. El ciclo reproductivo de esta especie sigue un ciclo estacional que se correlaciona negativamente con la temperatura del agua del mar, que coincide con un estado de madurez en el invierno, seguido de un periodo de desove que se inicia a finales de invierno y termina a principios del verano. Este periodo de puesta prolongado puede ser una estrategia ventajosa para la especie, ya que garantiza un suministro continuo de larvas. La gametogénesis comenzó a finales del verano/inicios de otoño y se intensificó con la disminución de la temperatura durante el otoño. El aumento del índice de condición, todavía durante la puesta, indica una recuperación rápida y una acumulación de reservas a finales del verano, que serán utilizadas en el siguiente proceso de gametogénesis. Las proteínas no contribuyen significativamente a la gametogénesis y el ciclo de glucógeno es típico de las especies conservadoras, una vez que la gametogénesis depende, en gran medida, de la cantidad de glucógeno almacenado. El almacenamiento de lípidos y su utilización indica la gametogénesis en el otoño/invierno, así como el proceso de acumulación de energía en verano.Palabras clave: almeja babosa, Venerupis senegalensis, composición bioquímica, índice de condición, ciclo reproductivo.
