SPERM STORAGE AND SPERM RESERVE USAGE IN FEMALE GUPPY(Poecilia reticulata)

Abstract

In this research, it was examined that how long and how many sperm could be used by female guppies from bundles of spermatozoa at the absence of males. Two treatments were conducted with five replicates in ten aquariums. In the first group male fish were held with females until first birth of female fish, and then they were taken away and never put together till the end of the experiment (9 months). On the other hand, in the second experiment group all female and male fish were kept together over the experiment. At the end of the trial, it was determined that female fish in the first group could use the sperm that they stored in their bodies nine times with nearly 28-day intervals.
