A standardized assessment of geographic variation in size at maturity of European lobster ( Homarus gammarus L.) in the North East Atlantic
Abstract Assessing size at maturity for European lobster Homarus gammarus across the North East Atlantic remains a fundamental knowledge gap for this commercially valuable fishery. This study for the first time collates existing data on physiological maturity of female European lobster H. gammarus a...
