Ectoparasites can attack on pacific white shrimp (Litopenaeus vannamei) which are kept in high density concrete ponds. The purpose of this study was to determine the type, prevalence, infestation and intensity degree of ectoparasites pacific white shrimp Postlarva (PL11-PL15) stage and Postlarva (PL20-PL30) stage in Bangil ponds that are cultivated with high density. The method used in this research is a survey method with random sampling. Data were analyzed using T test. The results of this study indicate that there are three genus of ectoparasites both in the pacific white shrimp PL11-PL15 stage and PL20-PL30 stage, namely Zoothamnium sp., Vorticella sp. and Epistylis sp. The prevalence of ectoparasites in pacific white shrimp is in the PL20-PL30 stage at 100% while the prevalence of ectoparasites in the PL11-PL15 stage is 75%. The level of ectoparasite intensity that attacks the pacific white shrimp (PL11-PL15) includes a moderate category of 21.8 individuals/head, while the level of intensity of ectoparasites that attacks the pacific white shrimp (PL20-PL30) includes a very severe category that is 814.05 individuals/head.
