Initial results have be achieved if many people and organisations proved to be extremely interesting. Once come together to tackle the problems collectively. experiments have been completed, the results will be published.

A paucity of robust silver eel data led to yellow eel data being used as a proxy to estimate silver eel escapement during the development of Eel Management Plans that were published in 2010. Virile (left) and signal (right) crayfish Virile crayfish Orconectes virilise have been Throughout the summer, electro fishing surveys present in the River Lee since the early 2000s have been conducted on the River Ash in where it was found in a small semi-connected Middlesex to ascertain the yellow eel population. pond in Enfield.

The species is indigenous to southern Canada, The aim of the investigation is to identify the ratio however it is found as an non-native invasive of yellow eels to silver eels. This ratio may then species in both Holland and in the River Lee in be applied to other yellow eel datasets to provide South-East England. Little is understood about a definitive estimate of silver eel escapement.
