Llyn Tegid was visited in late October 2014 and, over two days, eight survey-stations situated around the lake were monitored (those used on nine previous occasions since 1999) for the presence of the snail (and associated molluscs) using the sampling procedures as detailed in the Conservation Objective. M. glutinosa was found at all 7 sites where it had previously been recorded in numbers that, using Condition Assessment standards, allows the status of the snail to be judged as in a Favourable Condition in the lake in 2014. The population has been in Favourable Condition since standardised monitoring first took place in 2002. The habitat at all of the sites was also judged to be in ‘good condition’ in 2014. Results from surveys undertaken since April 2000 are also included in the report. Following status monitoring work a live sample of M. glutinosa was taken under licence from NRW from the lake survey to allow captive observation of the snails to be undertaken and to investigate the possibility of captive breeding of the snail. Initial observation of the captive Myxas has revealed that the snails emerge from beneath stones in darkness and feed upon encrusting algae both on stones and glass tank sides. Myxas bred in captivity at the end of the experiment.
