title: Motility of the spermatozoa of rainbow trout, Salmo gairdneri, in solutions of various salinities as studied by quasi-elastic light scattering.
abstract: Quasi-elastic light scattering (QELS) was used to study the motile properties of rainbow trout spermatozoa. It was possible to make motility evaluations at 10-sec intervals and to use the time course of these evaluations to study the effect of various concentrations of NaCl on motility. Concentrations of approximately 5% by weight were found to best prolong active swimming. Also, it was found that the motility of undiluted samples could be initiated after storage at 4 degrees C for at least 24 h.
