Growth Performance of Catfish (Clarias gariepinus) in Biofloc-Based Super Intensive Culture Added with Bacillus sp.

Abstract

This study was conducted to study growth performance of catfish (Clarias gariepinus) in bioflocbased super intensive culture added Bacillus sp. cells addition. Biofloc cultured in separated aquarium (100 L) was used as source of inocula for cultivation for C. gariepinus (average body weight of 2.3±0.12 g fishG 1

Production Performance of Catfish (Clarias gariepinus Burchell, 1822) Cultured With Added Probiotic Bacillus sp. on Biofloc Technology

“…Meanwhile, for the second harvest, they were fish in ponds K1, K2, K3 (1.20 ± 0.11), and K6 (1.22 ± 0.11). This result relatively similar compared with the prior study, where the Feed conversion ratio of catfish grown in biofloc culture 0.91-1.42 (Yusuf et al, 2015).…”

“…Production performance parameters include weight growth, growth rate (GR), specific growth rate (SGR), and survival rate (SR) referring to the Solanki et al (2012), and the feed conversion ratio (FCR) refers to Yusuf et al (2015). Growth was observed by sampling at weeks 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11 of culture.…”

“…This is not an experimental application but is already an industrial scale, this research is a continuation of previous (Yusuf et al, 2015). Ponds used 9 units of circular tarpaulin material with a metal wire mesh frame 7 mm.…”

“…If the result was negative continued standard test feasibility of the probiotic bacteria by sample dilution of molasses, bacterial isolated, TPC (Total plate count) test, if it produces minimal 1 × 10 6 CFU/ml Bacillus sp. (Yusuf et al, 2015) then probiotics are ready to use.…”

A Positive Impact on Coastal and Marine Environment By Implementation of Biofloc System

“…By using the Biofloc system the can increase protein levels up to 38% and also can provide free amino acids such as alanine, glutamine, arginine and glycine which are acts as attractants also [23][24][25] and also containing essential fatty acids, minerals and vitamin 'C' which enhances the not only growth and also the immune system [22,26,27]. During the culture of cat fish also observed specific growth rate and low FCR levels with Biofloc technology [28]. The BFT system implemented ponds shown low FCR and also with good survival rates [29,30].…”
