Abstract
A method for determining the clearance rates of suspension-feeding organisms by means of a fiber-optic colorimeter is discussed. The fiber-optic probe facilitates direct measurement of the turbidity of solutions without the need for removing subsamples. This allows for continuous monitoring and overcomes problems associated with calculating clearance rates if subsamples are removed. Standard curves are provided for plastic microspheres of six sizes (0.497–45.8 μm diameter), at concentrations of 0.8–100 mg/L, for each of four light-path lengths (1, 2, 5, and 10 cm). An experiment using the freshwater unionid mussel Truncilla truncata is described as an example of the use of this method.
