Book Review: Freshwater Fishes of Britain
The Author
Jack Perks
Review by Nick and Caroline Robertson-Brown
Whilst it may seem a strange book to be reviewing in the photography section of Scubaverse, underwater photography in freshwater lakes, rivers and streams, has become far more popular than it was in the last few years. The publication of this book, along with the work that Paul Colley has been doing with his remotely fired underwater cameras, has certainly made a few people pay attention to the wildlife that lives in our freshwater habitats.
The book is very reasonably priced at £16.99 and its finish and presentation is what you would expect in a book published by Reed New Holland. The book is full of great images that must have taken time and dedication to capture, as there are some 56 species covered in these pages. The content of the book is made up with a dedication, a forward, an introduction and a short guide to fish twitching. Most of the fish that you are likely to see in UK waters are covered, including a few oddities and variants, which Jack talks about towards the end of the book. Jack also talked about fish conservation and how most of our rivers are in very poor condition with only 17% of them classified as being in good health. Pollution is a major threat to fish, and this includes the oils and toxins that are washed off the road, the pesticides and herbicides that are leached into the rivers off agricultural land and micro-plastics and contraceptives flushed into the water supply which alters the biology of the fish. He also talks about invasive species, such as Signal Crayfish, which devour the eggs and fry of our native fish.
The book is well-written and all species are illustrated with at least one photograph and includes a brief description of the species, including details of the main distinguishing features habitat and breeding habits. The book is also littered with interesting facts about many of the individual species, such as why the Tench is sometimes called the doctor fish.
The book is an easy read by a wildlife photographer who has written and photographically illustrated dozens of articles for magazines such as BBC wildlife. He is a lecturer at Nottingham University for the MSc biological photography and image course so you can assume the knowledge he is passing on to the readers is well researched. I come for one, really enjoyed reading this book and it has inspired me to get my underwater photography gear into some freshwater streams.
Freshwater Fishes of Britain by Jack Perks is published by Reed New Holland at £16.99, hardback, and available from all good bookshops, Amazon or call 01206-255777.

Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.
The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.
Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.
In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.
Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.
Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.
The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.
Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.
Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.
