L\arvae of Anisakis sp. predilection for fish digestive tract including intestine, stomach, liver, gonads, eggs and fish muscles. The purpose of this study was to determine the presence of Anisakis sp. and look at the prevalence rate and the degree of infection of Anisakis sp. on mackarel fish, skipjack tuna fish, mullet fish, and sardine fish. The research method was carried out by taking 120 fish samples consisting of 30 mackarel fish, 30 skipjack tuna fish, 30 mullet fish, and 30 sardine fish in fish sale place, Sulamu District, Kupang Regency.
