Received on May 1, 1985; accepted on April 1, 1986 Fixation with glutaraldehyde in seawater is shown to be effective in reducing the loss of dry wt associated with preservation of plankton. Loss of dry wt from several plankton species and from bulk plankton samples was negligible. Organic weight loss was significant in some experiments, but less than that caused by formaldehyde. In a single experiment, carbon loss was zero, but nitrogen loss was high.
