The prevalence and intensity of ectoparasites infecting vanname shrimp (Litopenaeus vannamei) reared in different ponds

Abstract

Vanname shrimp can be cultivated in the base of different ponds, i.e. soil pond, concrete and plastic. These three different ponds have different impacts on the cultivation process. The purpose of this study was to identify the genus of ectoparasites and to calculate the prevalence and intensity of the ectoparasites that infect vaname shrimp in a soil pond, concrete and plastic pond respectively. The method used in this study was a survey method from three locations. The number of samples was 5% each. The prevalence of the ectoparasites that infect vaname shrimp was 95% in soil ponds (almost always), 73.33% in plastic ponds (usually) and 94.17% (almost always) in concrete ponds. The intensity of ectoparasites in soil ponds was 69.08 zooid / tail (weight), plastic ponds was 3.02 zooid / tail (light) and 60.96 was for zooid / tail in concrete ponds (heavy). Further research is needed to identify the infecting endoparasites in vanname shrimp cultivated at the base of different ponds.
