International Journal for Parasitology: Parasites and Wildlife, 2021 Since the seal populations in the North Sea are again thriving, the rationale behind seal rehabilitation is currently under discussion. Seals frequently require rehabilitation as a result of a lungworm infection, with these infections most commonly seen ...

Monitoring trends in the abundance of harbour seals (Phoca vitulina) in Icelandic waters
NAMMCO Scientific Publications, 2010 Harbour seal (Phoca vitulina) numbers along the coast of Iceland were monitored by aerial survey in the period 1980-2006. Trends in the abundance of the harbour seal population on the whole coast and in coastal regions of Iceland waters were estimated ...

Investigating monitoring options for harbour seals in Special Areas of Conservation in Scotland [PDF]
, 2007 Managing a wild population effectively requires knowledge of the abundance and behaviour of the species. Harbour seals (Phoca vitulina) are usually counted when they come ashore at haul-out sites, and so it is important to understand how the number of ...
