Abstract


This research was conducted from May until June 2016 at Laboratory Aquaculture of
Technology Faculty Fisheries and Marine Science, University of Riau. The purpose of this
research was to investigate growth and survival rate of striped catfish with probiotics dosage is
different in bioflocs techniques. This research using experimental method and completely
random design (RAL) one factor with three treatment there are P0: without giving probiotics
(control), P1: probiotics giving 5 ml/m3, P2: probiotics giving 10 ml/m3, P3: probiotics giving 15
ml/m3. The result showed that maintenance striped catfish with probiotics dosage is different
giving affect significantly on the growth of absolute weight, absolute length growth, but not
affect significantly on the survival rate and food efficiency, specific growth rate and food
conversation rate (FCR). The best treatment were obtained in treatment three (P3) with
probiotics dosage giving 15 ml/m3 with value growth of absolute weight 7,08 gram, growth in
absolute length 3,85 cm, specific growth rate 3,69 %, food efficiency (EP) 70,06 %, food
conversation rate (FCR) 1,51, flock volume 2,1 ml and survival rate 58 %.
