摘要：

Milt was collected individually from rainbow trout (Oncorhynchus mykiss), whitefish (Coregonus clupeaformis) and yellow perch (Perca flavescens) and sperm density measured by three different methods: measuring spermatocrit value, counting sperm using a Neubauer counting chamber, and by measuring absorbance at 505 nm. Sperm concentration significantly differed between yellow perch (41.58 +/- 3.5 x 10(9) ml-1) and the two other species, rainbow trout (11.80 +/- 6.19 X 10(9)) and whitefish (7.95 +/- 2.5 7 x 10(9)). In diluted yellow perch sperm and directly sampled sperm of whitefish and rainbow trout, correlation coefficients were highly significant between spermatocrit, counting, and the spectrophotometric method of measurement. It is suggested that sperm concentration measured by optical density offers a quick and accurate method of determining sperm concentration.
