Magical Messingham Sand Quarries

Spent a wonderful couple of hours this morning watching first a shoal of fish which were probably Rudd and then two battleships came cruising in (see third video below) which I think were either Tench or some sort of Carp?(Just been told they're Bream so completely wrong)  But then we had half an hour in total, watching two Otters playing and fishing in front of the Duck Hide – now I know nothing about Otters so if someone can perhaps age/sex the pair it would be great – one was much paler than the other and had a bright pink nose – at one stage a large Eel was caught and they then disappeared only to re-appear ten minutes later.
