Cycle de reproduction de la moule Mytilus galloprovincialis Lamarck 1819 au Maroc

Abstract: Résumé :L'étude du cycle de reproduction de la moule Mytilus galloprovincialis a été réalisée au niveau de deux sites situés sur le littoral atlantique marocain : Cap Beddouza et Imessouane. Pour cela un échantillonnage mensuel a été réalisé sur une période de deux ans depuis mars 2009 jusqu'au mars 2011. L'étude histologique et pondérale (indice de condition) des cellules folliculaires a montré que l'activité de la gamétogénèse est bien développée tout au long de l'année chez la population soumise à un upwell… Show more

“…We presume, that a mussel's sexual maturity occurs during early spring and early winter and the sexual rest occurs during the summer and fall. Bhaby et al (2011) observed the same pattern in the reproductive cycle in a population of mussels in Beddouza Cap on the Moroccan Atlantic coast, with a break of gametogenesis between May and July and an initiation of gametogenesis between July and October with a low sexual development in winter. In the same sense, Schmidt et al (2013) suggests, also, two spawning events, the first in spring and the second in late summer/autumn in this species in Galway coast, Ireland.…”

“…Intensive spawning in this area occurs between spring and summer but the process of both emission and rapid redevelopment of gametes take place simultaneously through seasons. During studied period, the temperature and salinity of the site coastal waters were varied respectively between 15°C and 21°C and between 35 and 37 [24]. Ciliophora-like ciliates and S. mytilovum were present throughout the reproductive cycle of the M. galloproviencialis during the surveys.…”

“…Until 2000, there was only one scientific publication about the general reproductive biology of the M. galloprovincialis, discussing the multiple peaks of gonad maturation [3]. After 2000's, there were two papers of reproductive biology of M. galloprovincialis in coastal water of Mediterranean Sea and the Atlantic coast of southern Morocco with detail investigation with histological analyses [4,5]. There are still many observed habitats and aggregations of M. galloprovincialis along Moroccan coast, and those few investigations are not sufficient to understand the natural populations and to monitor their status.…”

“…The reproductive tissue of sexually matured M. galloprovincialis accounts for more than 59% of the weight of the soft tissue [10] or more than 95% of the mantle. Reserve cells in the mantle, the ADG cells, has been observed in histological specimen, and the seasonal variation of number of ADG cells has been investigated [4,11]. The stored nutrients are released during gametogenesis; this mobilization of reserves is followed by a phase of active reserve during the period of sexual rest.…”
