✦ Synopsis

Veliger larvae of Mytilus edulis (L.) from Menai Straits, North Wales, were maintained for up to 2 mo during 1981 at 5 ~ and then grown on to metamorphosis at 17~ Larvae so treated showed similar low mortality and equivalent spat production to control larvae. Growth rate at 17~ was less in treated larvae than in controls, but treated larvae grew a little during the period at low temperature. Larvae ofPecten maximus (L.) from the Irish Sea suffered high mortality at low temperature but larvae surviving 2 wk at 8 ~ could be grown on to spat at 17 ~ The longevity of M. edulis larvae is discussed in relation to the genetic homogeneity of adult populations around the UK.
