Can anyone recommend a good fish ID/marine life book for Uk waters?
There are quite a few good ones depending on what level of information and what budget you are looking at but I can recommend 'Marine Fish and Invertebrates of Northern Europe' by Frank Emil Moen & Erling Svensen and Great British Marine Animals by Paul Naylor which are both available from the BSAC shop. These are both quite detailed and informative containing information about habitats as well as species.
The Marine Conservation Society field guides are very good too with easy to follow formats detailing the most common species.
I have put a couple of links in below to these sites.
