Abstract
This study was carried out to investigate the parasites of the shrimp Panaeus monodon collected from Iguoriakhi River, near Benin City in Ovia North East Local Government Area located between Longitude 005 °25’55.0 - 005 °29’36.20E and Latitude 06 °23’42.76N - 06 °27’10.15N. Live shrimps were collected from
November 2021 to February 2022. A total of 101 shrimps were examined, out of which 49(48.5%) were infected with parasites. A total of 59 trematode metacercaria
were extracted from infected shrimps with overall mean intensity of 1.20±0.00. Shrimps examined in February had the highest parasite prevalence of 100 %. The
results also revealed that pasitic prevalence increased in shrimps as their sizes increased, however a drastic decline was observed in larger shrimps with length
between 711.5 - 15.49. Shrimps with length between 7.5-9.49 had the highest revalence with an overall mean intensity of 1.03±0.00. The results of this study
suggest that the black tiger shrimp is susceptible to parasites that can cause health complications when consumed. Therefore care should be taken to avoid human
infection.
