Install climbing structures for fish
A study in 2011–2013 in a river in West Virginia, USA (Welsh & Aldinger 2014) reported that an eel ladder at a dam was used by some yellow American eels Anguilla rostrata to migrate upstream. Eight years after the eel ladder was installed, 177 eels were recorded using the ladder over a 15-day period. Ten years after installation, 1,184 eels were recorded over a five-day period. Eels were 223–530 mm long. An eel ladder was installed at a dam in 2003 to assist upstream passage of migrating eels. Eels passing through the eel ladder were photographed using an infrared motion sensor camera (see paper for details). Eels were monitored for 15 days in July 2011 and five days in July 2013. Eel length was recorded for 251 eels.
