Freshwater Shrimp

Freshwater Shrimp

The Freshwater Shrimp (Paratya australiensis) is a tiny, opaque, prawn-shaped invertebrate which is widespread throughout most freshwater lakes and streams on the eastern seaboard. It grows to approximately 7cm in length and is a prolific breeder, producing eggs year-round. Eggs are held by the female under the tail where she protects the eggs until they hatch.

Freshwater Shrimps feed on decomposing organic matter and algal films on rocks, wood and other surfaces. These crustaceans form a vital component of the food chains in freshwater ecosystems and make up a large proportion of the diet of the recreational fish species, such as Australian Bass (Macquaria novemaculeata), which are found in our freshwater lake systems.
