Abstract

SendangBiru waters is the part of Indian Ocean in East Java Indonesia with high capture of tuna. Monitoring of Skipjack tuna (Katsuwonuspelamis) health status using parasitological approach have investigated for supporting the marine bio conservation and sustainable fisheries. Skipjack tunas that landed at Sendang Biru Port Fisheries were directly examined and preserved prior to further analysis of parasitological parameters including prevalence (P), mean intensity (MI) and heteroxenous/monoxenous (H/M) ratios.Then, the calculated of P and MI were qualitatively expressed as infection status refer to infection rate based on what is stipulated by Williams and Bunkley-Williams. There were found five genera of parasites,i.e. Necator, Trichinella, Capillaria, Rhadinorhynchus, and Eimeria. The Rhadinorhynchus was observed as the highest infectious parasite (P=83%; MI= 83.16 individuals/infected fish). The infection status of intestinal parasites in Skipjack tuna from SendangBiru Waters were categorized low, often and moderate infection with H/M ratio was 3:2.
