| Abstract | ||
| Many parasitic fish-borne zoonoses have primarily affected humans, especially in low and middleincome countries. The present work aims to investigate the infection by helminth parasites in Nile-Perch Lates niloticus (Linnaeus, 1758) collected from Nasser Lake in Aswan governorate, Egypt. Out of 25 fish samples (15 males & 10 females), seven (28%) had nematode infections. The mean intensity and parasitic abundance were 202±345 and 56.56 respectively. The infestation index (IX) was 15.84. The infection in males was higher (33.33%) than (20%) in females. The nematodes were found in the abdominal cavity or externally connected to the stomach and duodenum in a tightly capsulated spiral shape. Using the light microscope, the nematodes were identified and described based on their posterior end and cephalic area. It was discovered that they belong to the third-stage larvae Contracaecum Railliet & Henry, 1912 (Family Anisakidae). In conclusion, many parasite illnesses in fish have zoonotic significance, delaying the fish's reproductive maturity and increasing fish mortality so we must give great importance to these parasites, study them in detail and study their life cycle to demonstrate their role in affecting aquatic organisms, especially those of great economic importance such as fish, and try to find modern ways to combat and eliminate them to achieve a healthy environment free of diseases. | ||
