Salmon (and some Brown trout) delayed below Annacotty weir on the River Mulkear in the Lower River Shannon SAC, during late-December 2016. This weir is a difficult obstacle for even salmon, and many fish get left behind - especially during the low water conditions which prevailed during December 2016. We need a new fish pass for Anacotty weir to help all species. This is an impassable barrier for River Lampreys and a difficult barrier for Sea Lampreys and the critically endangered European #eel. However, this video shows how salmon also have problems here. Also refer to previous videos posted on this channel which show salmon repeatedly jumping at this weir but unable to ascend it. The poor water quality in the Lower River Mulkear is also apparent in this video, and this is a significant threat to lamprey populations which are generally confined to below this migration barrier.
