Palaemon kadiakensis, commonly known as the Mississippi grass shrimp, is a species of freshwater shrimp from the central United States, specifically the Mississippi River Basin.[2][3]

Early development

The eggs of Palaemon kadiakensis are 1.4 mm. long or about one twenty-fifth of the adult length.[4] In laboratory settings the incubation period of Palaemon kadiakensis eggs has been observed to be 24–28 days.[4]

After hatching a P. kadiakensis will go through six distinct larval stages before reaching its final adult form.[5] Among larvae reared in experiments, the duration of larval life was 16 to 24 days and the average length of larval life was 19.64 days.[5] In laboratory settings the larvae are fed Artemia salina Nauplius[4] or 100-500 micron sized commercial feed.
