The white-striped cleaner shrimp Lysmata amboinensis is a favorite ornamental species in Vietnam and worldwide, but the rearing conditions for larvae of this species has not been studied yet. Therefore, this study was conducted to determine proper conditions for larval rearing of white-striped cleaner shrimp Lysmata amboinensis. The experiment was designed as completely randomized design with 9 treatments, including 3 types of rearing water (disinfected water using chlorine, green-water and biofilter-water) and 3 types of tank (upwelling, Weis and Kreisel tank). Each treatment had 3 replicates, resulting in a total of 27 experimental units. The experimental units were tanks filled with 5L of one of three types of rearing water. The results showed that larval survival was similar among three different water types. Larval survival was higher in Kreisel tanks than in upwelling and Weis tanks. There was no interactive effect between rearing water and tank type on the survival rate of the cleaner shrimp larvae. Therefore, disinfected water (lower operation cost) and Kreisel tank are recommended for rearing of white-striped cleaner shrimps.
