Biofloc System Using a Bucket for Climbing Perch (Anabas Testudineus)

Climbing perch (Anabas testudineus) is a peat swamp fish with high economic value so has the potential to be developed. Bio floc technology can increase the growth of Climbing perch providing additional protein feed which can increase growth and feed conversion ratio. Bio floc technology can maximize limited land, is environmentally friendly, saves water and feed use, has no smell and waste water can be used as plant fertilizer. The aim of the research is to find out how the bio floc system using buckets affects the growth and survival of climbing perch. This research used a RAL with 3 treatments and 3 replications, treatment A (without bio floc technology stocking density of 30 climbing perch), treatment B (stocking density of 30 climbing perch), treatment C (stocking density of 45 climbing perch). The rearing of climbing perch was carried out for 2 months in buckets. The results of the research showed that bio floc technology using buckets had an effect on the growth in length and absolute weight of climbing perch (Anabas testudineus) in treatment C (absolute length 2.48 cm and absolute weight 3.73 g). The survival rate of climbing perch in each treatment was not significantly different with the highest survival rate in treatment C (84%), treatment A (79%) and the lowest survival rate in treatment B (76%). The results of water quality measurements temperature, pH and DO, are still within the normal range for the life of climbing perch.
