ABSTRACT
Globally, fishes are considered as the healthiest food. They consist of all the significant nutriments that are very necessary for human health. Diseases in fishes caused by invasion of parasite especially due to Philometra species is considered very much problematic in fish culture and aqua tilling. There are number of complications in fishes that arose due to presences of Philometra sp. Presence of these parasites directly affect fish reproduction and ultimately decline their populace. This research work was done to collect, observe and identify variety of nematodes (Philometrids) from female reproductive organs of marine edible fish Pomadasys maculatus (Bloch, 1793). Fishes were collected from Karachi coast, Kemari, further processed in parasitology lab, University of Karachi. Ovaries were inspected to observe presence of Philometra sp. and other parasites too. In a year, from February 2021 till January 2022, 120 samples of Pomadasys maculatus (Bloch, 1793) were examined out of which only 25 fishes were found to be infected. From Pomadasys maculatus (Bloch, 1793) two new gonad infectingPhilometra sp. were identified as Philometra pakistanii and Philometra maculati.
