<![CDATA[ABSTRACTThis study aims to determine the effect of giving Tubifexsp with different doses on the growth and survival of black ghost fish (Apteronotusalbifrons). This research was conducted in May – July 2019 at the Aquaculture Technology Laboratory, Faculty of Fisheries and Marine Affairs, Riau University, Pekanbaru. This study used a one-factor Completely Randomized Design (CRD) consisting of four treatment levels with three replications so that 12 experimental units were needed. The treatments were: Giving Tubifexsp 5%, 10%, 15% and 20% of the weight of fish biomass. The results of the research that have been carried out can be seen that the best treatment is feeding with a dose of 20% / body weight which can produce an absolute weight growth rate (0.51 g), absolute length growth (4.75 cm), specific length growth (2, 5 cm). 20%) and survival (86.67%) while the water quality parameters during the study obtained pH 6.0-7.0, temperature 26-28 0C, DO 3.1-3.2 mg/l.Keyword :Apteronotusalbifrons, Doses, Growth of Tubifexsp]]>
