Reproductive activity and biochemical composition of the pullet carpet shell Venerupis senegalensis (Gmelin, 1791) (Mollusca: Bivalvia) from Ria de Aveiro (northwestern coast of Portugal)

摘要: The present study characterizes the reproductive cycle of Venerupis senegalensis (=V. pullastra) from Ria de Aveiro (Portugal) as well its nutrient storage and exploitation strategy. followed a seasonal that correlated negatively with sea surface temperature, comprised ripe stage in winter by spawning period began late ended early summer. This extended may be an advantageous strategy for species because it ensures continuous supply settlers. Gametogenesis summer/early autumn intensified decrease temperature during autumn. condition index increased even period, which indicates there is rapid recovery reserves are accumulated summer used later gametogenic process. Proteins did not contribute significantly to gametogenesis glycogen pattern typical conservative species, since depends largely on amount stored. lipid utilization showed took place autumn/winter energy were
