Abstract

This study aimed to identify the types of parasites, prevalence, and intensity of parasitic infections in vannamei shrimp (Litopenaeus vannamei) in Teluk Mengkudu District, Serdang Bedagai Regency. The research employed a descriptive method using random sampling techniques at two traditional shrimp ponds. Shrimp samples were examined at the Zoology Laboratory, Faculty of Science and Technology, UIN Sumatera Utara. The observed organs included walking legs, swimming legs, and the tail. The results showed that three types of ectoparasites infected vannamei shrimp, namely Zoothamnium sp., Epistylis sp., and Vorticella sp. Water quality parameters indicated temperatures of 28–28.2°C, pH of 7.75–8.23, ammonia levels of 1.436–2.732 mg/L, nitrate levels of 1–1.1 mg/L, nitrite levels of 0.14–0.95 mg/L, dissolved oxygen of 0.91–3.56 mg/L, and salinity of 15.53–21.63‰. The conclusion shows that the highest prevalence was found in Zoothamnium sp. at 26%, while the highest intensity was 3.87 individuals per shrimp.   Keywords: Ectoparasite, Intensity, L. vannamei, Prevalence

Abstract

This study aims to identify the types and prevalence of parasites in tiger shrimp (Penaeus monodon) cultivated in ponds in Medan Labuhan District. Sampling was carried out at three semi-intensive pond locations with a total of 150 shrimp measuring 10-15 cm. Parasite identification was carried out through microscopic examination of the carapace, legs, and tail organs. In addition, pond water quality (temperature, pH, salinity, DO, ammonia, nitrate, and nitrite) was measured to assess its relationship with the presence of parasites. The results of the study found two types of parasitic protozoa, namely Epistylis sp and Zoothamnium sp with prevalences of 12.5% and 8.3%, respectively. Parasites mainly attach to the tail and legs which have fine hairs as attachment sites. Water quality analysis showed that ponds with low dissolved oxygen levels and acidic pH have a higher risk of infection. These findings emphasize the importance of water quality management, especially DO, pH, and nitrite to suppress parasite attacks and maintain the health of tiger shrimp.
