✦ Synopsis

We have compared the convenience and accuracy of two models using 6 shell dimensions for predicting 4 biomass parameters for 4 species of southern U.S.A. unionids (Quadrula quadrula, Q. pustulosa, Lampsilis anodontoides, and Amblemaperplicata).

Prediction of whole wet weight, tissue wet weight, tissue dry weight, and shell dry weight as a linear function of (shell length)3 was accurate, even with extremely small sample sizes. In addition, this method is very convenient for field use because it requires one simple, unambiguous shell measurement.

1. A population of the freshwater pearl mussel Margaritifera margaritifera L. was found in the River Narcea in the province of Asturias (north-western Spain). Primary analysis of the population shows that it is well distributed along the river and is particularly abundant in shady river banks with a
