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.

I have two long haired cats and these are by far my favorite lint rollers--super sticky and gets the job done in record time.

My son and I had checked this book out from the public library and he loved it! He was so upset when we had to take it back so I decided to look online. We love Mexican food/culture and he thinks it's so funny after knowing the original song!I was so happy to have found it for his birthday!

Ex Output:

Positive
