Abstract
A population of the marine polychaete Nereis virens at Brandy Cove, New Brunswick has been analysed on the basis of weight distribution in monthly collections made throughout a year. Gametogenesis, spawning and larval life were also studied and information which adds to or differs from earlier accounts is reported. An age structure is postulated, involving a lifespan of up to 6 years. Suggestions are made as to the age at which sexual differentiation and spawning normally take place. These conclusions are compared with the results of a reinterpretation of an earlier study on a British population of the same species.Keywords
