Q: I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.

A: Negative

Q: The book makes a great read, same as DHC's other books of the "Lost Cities" series. Very entertaining, thought provoking, and well written. One thing though: I don't get why the author keeps calling himself "a rogue archeologist": someone has to explain to him what archeologists do. DHC is no archeologist, whatever he might think; he's a traveler, a gossip gatherer, and a free spirit, but all this has little to do with archeology. I enjoyed his open-mindedness, and the relativism with which he judges most of the theories and hypotheses considered. Going through his whole opus, I can't help noticing that this writer is a really great guy, and that his travel companions and friends must have been lucky to have met him, but archeologist? Please, give me a break. And use some proofreader, for the next edition.

A:
Positive
