New paper: The potential contribution of small coastal streams to diadromous fishes conservation

As an example of the potential contribution of very small coastal streams to diadromous fish recruitment, G.H. Copp. T. Basic and F. Daverat report on the densities and distribution of European eel Anguilla anguilla L. and flounder Platichthys flesus (L.) in one such stream, “La Warenne,” in northeast France. Mean CPUE values for eel were similar to the highest densities reported for larger rivers of Great Britain, France and Spain in the Interreg Atlantic and North Sea areas. This small dataset illustrates that small coastal streams may represent an important, but overlooked, role in conservation strategies for European eel, and possibly flounder, indicating the need for further field studies and investigations of existing data sources to evaluate the contributions to diadromous fish recruitment of these poorly studied water courses.
