Yamato shrimp

[marco]

I have been keeping Yamato shrimps for some time but so far they have not showed any sign of pregnancy. My biggest shrimp is about 4.5cm. Are they too small to breed?

Yamato shrimps do not breed in freshwater.

Ya they dont breed in freshwater heard they only breed in blackish water. I have few berried but egg will not hatch.

What is the ideal salinity?

Hi, the salinity of brackish water is roughly 1.008-1.010. normal seawater is 1.021-1.024.

For yamato shrimps, when the eggs hatch, the young emerge as zoea, a type of zooplankton. they drift down the river and finally into the sea. Then, they live their zoea and megalopae stage in the sea, and after that they swim upriver back to the freshwater environment when they are biggger.

So, if you want to rear the young, you have to separate the berried female. when she has released eggs, put her back. in the rearing tank, slowly, really slowly increase the salinity until it reaches the salinity of seawater. meanwhile, you can feed them phytoplankton, and when they are bigger, you can feed baby brine shrimp.

Quite challenging to breed Yamato shrimp at home, I have not heard of a hobbyist who has succeeded yet locally.

Thanks for your great info.
