Abstract

A detailed study was conducted on the monthly variation in milt-volume, spermatozoa concentration and duration of motiUty of spermatozoa oi Rastrelliger kanagurta. Milt-volume showed peak (0.094 ml) in the month of May. Spermatozoa concentration did not vary much during the period of May to October (21.5-21.7 x lO'ml"'). Duration of motility in 100% seawater was observed to be maximum in the month of August (101.6 sec.) followed by October (96.53 sec.) and April (94.4 sec). The effect of various dilutions of seawater on the duration of motility showed a decreasing trend with decrease in concentration. Maximum duration of motility (86.46 sec.) was observed in 100% seawater.
