<![CDATA[This study investigates the types, prevalence, and intensity of ectoparasites and endoparasites in vannamei shrimp (Litopenaeus vannamei) farmed in intensive ponds in Lamteungoh Village, Peukan Bada District, Aceh Besar. A total of 40 shrimp were collected using purposive sampling. Parasite observations were conducted on shrimp organs including the head, gills, walking legs, swimming legs, and tail. Three ectoparasites were identified: Vorticella sp., Zoothamnium sp., and Epistylis sp., while no endoparasites were found. Vorticella sp. showed the highest prevalence at 100% and intensity at 19.35 individuals per shrimp. The tail was most frequently infected, with a prevalence of 82.5% and intensity of 9.81 individuals. Water quality data showed pH 6, temperature 26–27°C, salinity 25 ppt, and DO 2.4–2.6 ppm, which are considered suboptimal. Low dissolved oxygen levels and poor water conditions likely contributed to parasite proliferation. The absence of endoparasites may be linked to good management and the use of high-quality seed. This research provides useful insight into parasite threats in shrimp farming and underscores the importance of maintaining water quality for disease prevention and productivity.]]>
