Breeding zebrafish

That actually sounds pretty typical for the first breeding, especially of relatively young fish. It usually takes one or two spawnings, spaced at least a week apart, to "prime the pump" and consistently get good eggs from newly mature females.

If your embryos are dying, try increasing the volume of water you are keeping them in, making sure there is enough air in the container you are collecting them in (especially if it is something like a culture dish), and changing the water after the first 24 hours.
