The correlation between ectoparasite infestation and total Vibrio parahaemolyticus bacteria in Pacific white shrimp (Litopenaeus vannamei) in Super Intensive Ponds

Abstract This study aimed to determine the type, intensity, degree of ectoparasite infestation and its correlation total V. parahaemolyticus bacteria in super-intensive pacific white shrimp culture. In this study, sampling was carried out 3 pond areas spread East Java, namely Bangil, Tuban, Lamongan with 50 shrimps (PL30-PL 40). The obtained data underwent regression analysis. Based on results, there were three types ectoparasites, Zoothamnium sp., Epistylis sp. Vorticella High intensity found from Tuban ponds, 76 55 individuals/shrimp, respectively, showing heavy infestation. (1.16 × 10 5 CFU/gr) CFU / gr) ponds. coefficient value R = 0.807 positive increasing parasite low oxygen levels.
