| Breeding Processes Used by freshwater shrimp |
All female shrimp carry their eggs on the swimmerets. This is known in shrimp terms as berried.
They call it berried because the eggs look as if there is little berries were stuck to the bottom of the
tail. This is a critical point for the female. The worst thing that can happen to a berried female is
that she molts. If she does, the eggs go with it. Changes in water chemistry will make a shrimp
molt. Feeding should be cut down to a minimal 1 time a week and a very small amount during this
period. This is again to prevent molting. When the female drops her babies she should be removed
after that. A rest/reconditioning period should be allowed of at least 2 weeks before putting her
back with the male.

The first form of young development I will refer to as
Traditional. This means that they develop just like their
saltwater predecessors. In other words, after the eggs hatch
they are in a larval stage. They float back out into the bay or
ocean to develop into shrimp. After this point they then travel
back up the river system into the freshwater to live their lives
and breed.

The second form of young development is a semi-evolved
form. I will refer to this type of development as
semi-evolved. This type of development means that the eggs
hatch into larvae. The difference is that the larvae do not
need salt to develop. They will develop in full freshwater.
These types of shrimp can be bred in the aquarium, but an
old well-established planted aquarium is needed.

The third form of development is fully adapted for freshwater.
I will refer to this as completely evolved. This means that
when the eggs hatch they are fully functional miniatures of
their parents. The larval stage is developed while still in the
eggs, so when the eggs hatch, they are little shrimps. These
are the easiest shrimp to breed in the aquarium. The babies
need no special water requirements or foods.

If there is little or no information on the particular shrimp you are working with you can make
an educated guess on which type of development the babies have. This is done by the size of the
eggs. Small eggs usually mean they will be traditional or semi-evolved. If the shrimp have large
eggs they usually will be completely evolved. The extra egg size is needed for them to mature
into shrimp from the larval stage.
There are people that are working with the shrimp that have traditional-type baby development.
There are some good articles on this matter if you search for Macrobrachium rosenbergii. These
are bred in large numbers as a food item.
