Effect of Different Density on Survival Rate of Gourami Fingerling (Osphronemus goramy) Razor Size on Closed Transportation System

The low survival rate of gourami fingerling transportation is a problem. Setting the expected amount can lead to death. This research aims to determine the exact amount of density in the razor-sized gourami fingerling transported during the treatment period and to analyze its effect on the survival of razor-sized gourami fingerling. This research was carried out from April to June 2022. This research method used in the Factorial Randomized Group Design (FRGD) experiment consisted of two factors, namely the density factor of 4 levels (10, 20, 30, 40 fish/2L) and the three-stage transport duration factor levels ( 3, 5 and 7 hours). The transportation system in this study is a closed system. The parameters observed were post-transportation life, post-maintenance life for 7 days and water quality in the form of temperature, ammonia, pH and DO. Based on the results of research showed that the effective density for the transportation of razor-sized gourami fingerling was 30 fish/2L with a transportation duration of 5 hours and the survival rate post-transportation was 97.8% and post-maintenance 7 days was 90.02%.
