Aqua Simba Probiotic Application On The Sustainability And Growth Of Nirwana Tilapia (Oreochromis niloticus) Nursery II

Aquaculture

This study aimed to analyze the appropriate concentration of Aqua Simba probiotics in nurseries II nirwana tilapia (Oreochromis niloticus) feed so that it can produce the highest growth and survival. This research was carried out for 35 days from February 2021 to March 2021 at the Laboratory of Building 4, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method used is experimentally using a completely randomized design (CRD) with four treatments and five replications. The research data were analyzed using analysis of variance (ANOVA), followed by Duncan's multiple-distance test with a 95% confidence level if there was a difference in treatment. The treatment given was the addition of probiotic Aqua Simba with different concentrations into the nirwana tilapia nursery II feed which consisted of treatment without the addition of probiotics as a control, the addition of probiotics 3 mL/kg of feed, the addition of probiotics 5 mL/kg of feed and the addition of probiotics 7 mL/kg of feed. The results showed that the addition of probiotic Aqua Simba to nirwana tilapia nurseries II feed had an effect on survival, growth, growth rate, feed conversion ratio and water quality of nirwana tilapia nurseries II seeds. The addition of probiotic Aqua Simba with a concentration of 5 mL/kg of feed resulted in a survival rate of 89.09%, length growth of 0.79%, weight growth of 0.91%, daily growth rate of 1.64%, feed conversion ratio of 3.77 and with good water quality and still within the threshold for nirwana tilapia nurseries II.
