Data were then tabulated and analyzed by t-test to test the differences between the two groups. The results showed that the fish size group gave a significant effect on the number of Anisakis in the body of fish (p <0.05). The prevalence of fish in group II was 85% while the group I was 70%. The intestine becomes the most internal organ found as much as 120 Anisakis , followed by 75 stomachs, muscle 20 and abdominal cavity 45 in group II.
