Reproduction Preferences Additional Information

The reproductive characteristics of Venerupis senegalensis vary according to the environment. In Scotland, Quayle (1952) recorded breeding between May and September. However, in northern Spain, spawning occurred in March, April and May (Perez Camacho, 1980). Spawning occurred 2 or more times in a season in a population in western Norway (Johannessen, 1973b) and it has been recorded that spawning can occur up to 4 times per season in Venerupis senegalensis (studied as Venerupis pullastra) raised in a microsystem (Jara-Jara et al., 2000). The Spanish population of Venerupis senegalensis (studied as Venerupis pullastra) experienced constant mortality of 17.7% per annum between shell lengths of 11 and 50 mm (Perez Camacho, 1980) whereas the Norwegian population exhibited low mortality up to year 8 followed by mass mortality attributed to senility (Johannessen, 1973b).
