Parasites of fish constitute one of the major problems confronting modern fish culturists and pathological conditions arising from parasite infections. It assumes a high level especially under crowded conditions (Van Dan Broek 1979). Commonly, nile tilapia (O. niloticus) and galunggong (D. maruadsi) are staple fish food and common preference among Filipinos because of its affordability and availability in the Philippines. However, galunggong and tilapia are said to have endoparasites which may cause illness to people if eaten raw or undercooked. Since host fishes are commonly consumed by Filipinos, parasitesrelated or associated diseases can be warranted especially if these fishes are unsanitarily prepared or eaten half-cooked. This study is conceived as it warrants public health awareness and fish hosts are common to human consumption. A study of parasites and their prevalence in O. niloticus and D. maruadsi are useful if the species of fish is of aquacultural interest and commonly consumed by Filipinos.

Results and Discussion
Table 1. Incidences of endoparasites in O. niloticus and D. maruadsi Form Larvae Cyst Cyst Infected O. niloticus 0 (0%) 1 (6.67%) 9 (60.0%) 5 (33.33%) 15 Infected D. maruadsi 15 (100%) 0 (0.0%) 0 (0.0%) 0 (0.0%) 15
Table 1. shows that All of the samples of D. maruadsi are found to have the larvae form of Anisakis simplex. There are 10 hosts of O. niloticus infected with of Eimeria spp. which was 6.67% while the unknown protozoan was 60.0% which means that majority of the endoparasites that are found inside the intestinal...
