Great first stop for identifying common macroinvertebrates and gastropoda. Easy to use, pictures and descriptions are great.
They'll feed themselves after you've collected a few invertebrates to fill out the food chain. The only thing it runs short on is variety of bugs. This book stays on topics specific to limnology addressing substrate, water chemistry and other topics. You wouldn't want them all, this part takes up more than half the book.A great book for a hobbyist that isn't afraid to put plants in an aquarium and find out what else nature keeps in its limnos. A good dose of science and terminology for people who want to know how things work.
Best of all you won't have to feed your fishes after reading this book. You'll learn about lotic and lentic and other words to confuse your friends and spell checker, and impress the biologists within hearing distance. It starts with a conceptual approach of what affects biological life in fresh water But it doesn't go too far off topic; it stays focused on invertebrate life.The illustrations are superb. An excellent intro to freshwater invertebrates. You don't need a college level understanding of chemistry or biology to read this, but the biology would help.
But at 400+ pages adding the somewhat less common would create quite a tome.The first section is the only part that needs to be read from beginning to end the rest is written for reference starting with illustrations, then going into detail first on the order, then on specific (common) families.
The color drawings are detailed enough to help determine the differences in various species. All in all - Excellent Book. Be clear - the focus of this book is not specifically on fly-fishing, but more of a biological guide to aquatic invertebrates. There is a focus on stream ecology and some tips on how to collect and identify various species. (For a highly detailed description of mayflies and caddis for the fly-fisherman, I would recommend the titles "Nymphs, volumes I and II"). As others have already reviewed, I am a fly fisherman who purchased this book to get a better understanding of freshwater invertebrates other than mayfly and caddis species. This guide is well-written and not too difficult to follow, even for the beginner. For a beginner, this book is a great place to start, but is also a nice reference for those with a little more experience.
This books is easy to comprehend, and the plates are well defined. Extremely useful for ID'ing aquatic creatures.
It is a great basic guide that will be used as a reference tool and identification resource at an introductory level. My teaching partner and I will use this in our Freshwater Ecology class at the secondary level. Excellent for the money.
