Paperback. Condizione: 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.
