Mysis relicta collected from Cayuga Lake, New York, contained 21% ash, 15.6% lipid, 10.2% N, and 37.0% organic carbon on a dry weight basis. Quantitative data are given for amino acids in a hydrolysate of whole specimens. Digestion by brook trout resulted in the separation, but not destruction, of exoskeletal parts. Laboratory decomposition experiments (5–20C, 2–16 months) in phosphate‐buffered glucose, a sediment‐water mixture, and lake water alone showed that a chytrid fungus, tentatively identified as a species of Allomyces, was associated with the destruction of mandibles and probably other exoskeletal structures as well.
