Abstract
Summary Objective: Determine and compare the population structure and relative production of eels from different habitats across river basins; Investigate relationships between habitat and eel production in order to inform the transport of models from data-rich to data-poor river basins. Key Customer Purpose: Further our understanding of the relationship between habitat and eel production in England and Wales, to support Defra’s responsibility for the assessment and management of eel populations by improving our ability to model eel production across river basins and transporting the model application from data-rich to data-poor basins.
