[cool][#0000ff]"Sterile" does not mean incapable of developing reproductive organs...eggs and milt. It merely means that the eggs are not fertile. At least most of them are not. Some do actually get fertilized but the fry are very weak and don't survive. [/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]There are both male and female wipers...with the appropriate organs. And they do develop eggs and milt at the appropriate time and are driven by the same urges to spawn. Don't know why they call it a false spawn because it is very much a spawn. Maybe because their efforts are all for naught.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Some "lab sterilized" fish...like triploids...do not even develop eggs or milt. They just eat and grow. And some "cross genus" hybrids...like the tiger trout...are neither male or female. However, some do develop physical characteristics and colors representative of either male or female...but none ever produces eggs or milt.[/#0000ff]
