Abstract

The ctenostome bryozoan Alcyonidium diaphanum is widespread and abundant in the coastal waters ofEngland and Wales.I t was recorded in 77^90% of beam trawl catches in the eastern English Channeland southern North Sea, and in 53^73% of catches in the Bristol Channel and Irish Sea.The maximumcatch rat...
