I've recently started a project breeding Macrobrachium scabriculum. They have a life cycle similar to bamboo and amano shrimp. That is, their larva are hatched in fresh(ish) water and then mature through their planktonic stages in water with progressively higher salinity content.
There are multiple considerations to take into account if you want to do this.
1st. Have a nursery/hatchery with freshwater. The hatchery should ideally be a cylinder with rounded corners (no right angles). I did this by using a 5g bucket and a plastic bowl, cut to fit tightly in the bottom of the bucket).
2nd. Have the propper foods to nurture the zoe (hatchling shrimp). Brine shrimp and powdered alage, and marine green water work great. Make a couple of brine shrimp hatcheries from 2liter soda bottles. Google brine shrimp hatchery for instructions.
3rd. Have marine salt on hand to slowly increase the salinity, as the larvae mature.
4th. Have another nursery tank on hand for the post larva to mature in. This will need to be cycled freshwater, free of ANY preditors.
5th. Be very patient. Document everything you do. If something doesn't work, keep track of it. Make one, or few small changes. Avoid multiple adjustments at once.
Bamboo shrimp have never been successfully bread in captivity, that I know of. I have spoken with over half a dozen who are trying, or have tried, over the years. It seems daunting, at first, but if you break it down into steps, it is not as over whelming.
Set simple goals. such as, successfully hatch zoe. Successfully reach larval stage X. Etc.
You can, and should have multiple hatcheries going, incase you have multilpe broods ready to hatch at the same time.
