The potential contribution of small coastal streams to the conservation of declining and threatened diadromous fishes, especially the European eel
Abstract Human‐generated pressures are continuing to have a detrimental effect on diadromous fishes, resulting in legislative initiatives to conserve and manage these species.

Abstract Human‐generated pressures are continuing to have a detrimental effect on diadromous fishes, resulting in legislative initiatives to conserve and manage these species. Field studies to inform these initiatives focus almost exclusively on larger marine, estuarine, and inland waters, neglecting the role of small coastal streams and tributaries in population recovery.
