Discover how scientists study freshwater mussel growth and movement, to support profitable mussel propagation.

This non-fiction work documents field methods used to track growth, aging, and migration of Unionidae mussels. It covers plans for collecting and tagging hundreds of specimens, measuring them with precise tools, and returning them to their habitat for ongoing observation. The material also explains how researchers select planting sites and monitor both natural and transplanted populations.

Learn how mussels are marked and tracked, including shell scratching and serial-numbered tags.
See how field records are kept, from weights in grams to measurements in millimeters.
Explore planting and reclaiming experiments in Oklahoma streams and ponds, with notes on habitat and movement.
Understand how growth lines, rest rings, and seasonal changes help estimate age and growth for economic species.

Ideal for readers of field biology and early 20th‑century ecological work, especially those curious about how science informs commercial propagation of freshwater mussels.

�valuation du vendeur 5 sur 5 �toiles

Paperback. Etat : New. Print on Demand. This book examines the growth and migration of freshwater mussels by studying specimens in the field over 5 years. The author specifically wanted to determine if the rings commonly seen on mussel shells mark yearly increments as has often been assumed. Results show instead that multiple rings can form in one year and wide rings can appear several years apart, rendering commonly used visual inspection methods unreliable for determining age. Slow growth and maturation of mussels has implications for commercial propagation, and the author presents data to help researchers working in this area. The book contributes to the field of ecology as well as the practical knowledge of mussel habitats and behavior. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N� de r�f. du vendeur 9781527741638_0
