Most of today’s catch belonged to a similar age class, although a much larger eel was observed further upstream near the cemetery later that day. Look out for eel traps along other rivers such as this one at Teddington Lock Emptying the trap Kingston University is running another eel training event during May, so if you are interested in helping out at any point from April to September with the checks, please sign up for the training (see the Kingston University biodiversity blog). Some not so good news with the river monitoring (see March, 2015 posts) : three out of the four RMI monthly checks have found breaches in trigger...
