Bopyrid isopod (Probopyrus buitendijki) was identified in the branchial cavities of the fresh water prawn, M. malcolmsonii from grow-out culture pond at Kuriyamangalam, India. Macrobrachium malcolmsonii is a new host for P. buitendijki. A total of M. malcolmsonii were checked for this study. The overall prevalence of the parasitic.

  Host-parasite Relationship Female P. consolidatum filled most of and were tightly lodged within the host's branchial chamber, producing a characteristic bulge in the host's branchiostegite. Male parasites oriented perpendicularly to the female's body axis on the ventral side of the female's abdomen. Host-parasite interactions are complex, compounded by factors that are capable of shifting the balance in either direction. The host's age, behaviour, immunological status, and environmental change can affect the association that is beneficial to the host whereas evasion of the host’s immune response favours the parasite. In fish, some infections that induce mortality are age and temperature Cited by:

Survival of the branchial ectoparasite Probopyrus pandalicoia through ecdysis of the host. Palaemoneles pugio, was studied by observing infected shrimps before and after ecdysis and directly with time-lapse video.

The parasite pair retained its position through % of Temperature, season, host age, sex, and reproductive condition affect energetics for host-parasite systems. Probopyrus pandalicola has little effect on host assimilation efficiency.

In the present study, infestation by Probopyrus sp. occurred mostly in males of P. pandaliformis, differently from studies conducted on other carideans, in which parasite prevalence was either.

Preliminary observations indicated that the grass shrimp, Palaemonetes pugio, parasitized by the isopod, Probopyrus pandalicola, captured significantly fewer prey items (Daphnia) and exhibited reduced activity compared to unparasitized conspecifics.
