- rowth is influenced by several factors, one of which is on the width. Solid density influences growth rates, feed efficiency and survival leading to production levels. One container for raising broodstock that utilizes the existing aquatic environment is the floating net cage. The aim of this research is to find out the best quadrupled maintenance of lelumbo on floating ponds in the waters of the lake. This research was conducted at the Laboratory of Aquaculture Experimental Pool, Faculty of Agriculture, Sriwijaya University in November-December 2018. The parameters measured include growth, survival, feed efficiency and water quality. The results showed that the P2 treatment (at a width of 50 tails / m3) was the best behavior that resulted in the growth of absolute weight of 8.52 g, growth of absolute length of 4.33 cm, survival of 100% and feed efficiency of 94.90%. Water quality during research is still within the range that can be tolerated by African fish. Water temperature ranged from 26.26 to 32.84 ° C, pH ranged from 4.0 to 4.3, dissolved oxygen was ranged from 5.1 to 5.9 mg. L-1 and ammonia ranged from 0.14 to 0.28 mg. L-1.
