The orange red shining spot on the second cheliped where the movable finger joins with palm makes it appealing in the aesthetic sense. This species is found to breed in captivity also. For the effective management of the prawn in the aquarium, a thorough knowledge on the various aspects of its reproductive biology is a prerequisite.
The various aspects of reproductive biology dealt with are
1. Taxonomy
2. Sexual dimorphism
3. Breeding dress
4. Maturity stages and ovarian development
5. Fecundity
6. Moulting
Since the species do not exhibit sexual dimorphism in size, it is difficult to identify male and female. The difference in colour of antennular flagellum between sexes becomes useful especially when they are bred in captivity.
The data on maturity stages and also the time of ovarian development finds its use especially in the aquarium rearing.
The fecundity studies gives an idea of the number of offsprings which could be produced from a single brood .
