Unfortunatly I was unable to view the pictures,is that you or me? Recent articles in Carpworld leave me in no doubt, that an Otter could cause serious damage to a fish many times larger than the one in question. There is no doubt that they can catch and kill large carp. A pike with its smaller girth should in theory, be potential pray. Otters have been reintroduced into our river systems, that no longer have the biomass of fish to sustain them. This has led to otters raiding still waters for their fish, which have no defence against such an efficient preditor. And we thought Cormarants were a problem!
