Biological performance and water quality of Asian redtail catfish, Hemibagrus nemurus cultured using duckweed as a phytoremediation

Abstract Asian redtail catfish, Hemibagrus nemurus is one of the local species that have an economical values in Southeast Asia including Indonesia. The research aims to obtain optimal duckweed biomass as phytoremediation on survival, growth, stress response, and water quality dynamic catfish culture. different duckweed, Lemna sp a treatments were followed A) 0 gram (control); B) 20 gram; C) 40 D) 60 gram. Three replicates performed for each treatment. 12 fiber thanks with size x 40cm set up where thank was stocking 50 fishes. result showed affect biomass, blood glucose (P<0.05). absolute yield also significantly Water during culture such nitrite, nitrate, total ammonia, phosphate concentrations at control (0 gram) highest compared others dissolved oxygen (DO), pH temperature relative constant. can be recommended culturing seed order increasing productivity keep range.
