Abstract
This study aims to determine the best acclimatization time for survival rate and growth of vaname shrimp. This research was carried out of for 22 days, started from February 5 to 26, 2021 at the Laboratory of Aquaculture Study Program, Faculty of Agriculture, University of Mataram. The research method used a completely randomized design with 5 treatments and 3 replications. Thus in this study there were 15 experimental units. As a treatment is the difference acclimatization periode was the decrease in salinity as follows : Treatment 1 : no decrease in salinity (30 ppt). Treatment 2 : 1 day decreased salinity (30 ppt, 0 ppt). Treatment 3 : 2 day decreased in salinity (30 ppt, 15 ppt, 0 ppt). Treatment 4 : 3 day decreased in salinity (30 ppt, 20 ppt, 10 ppt, 0 ppt). Treatment 5 : 4 day decreased in salinity (30 ppt, 23 ppt, 15 ppt, 8 ppt, 0 ppt). The results showed that the vaname shrimp that were kept at low salinity using acclimatization method had noticeable effect on survival rate. The value of survival rate between 1 % - 73 %, has an absolute weight between 0.0433 gram – 0.1802 gram and an absolute length bewtween 1.1 cm – 2.9 cm with food conversion ratio 0.1285 – 3.937. The oxygen consumption rate between 0.073 – 0.113.
