Short answer from a very tired and exhausted boy....
I've found about 15 percent with ovaries. The rest are probably male, however a lot of those don't show milt when squeezed.
I've never heard of a single instance of successful reproduction in a pond.
If an appropriately sized LMB presents himself to a hybrid striper, he might get eaten. The hybrids are not known however for actively targeting LMB.
