Purpose Rising demand of fish generates various pressureson aquatic ecosystems, causing its deterioration and theloss of its biodiversity. With the aim of a better managementand fish production in a salubrious environment, thisstudy proposes the utilization of organic fertilizers fromrabbit manure.Methods The treatments consisted of manure of rabbits fedwith: manufactured diet (T1), improved diet with Ipomeaaquatic (T2), improved diet with Elaeis guineensis (T3),and improved diet with Panicum maximum (T4). Indeed,experimental design was a completely randomized blockdesign with three replications. 6 g in 10 L of water fromthe different manures from each diet was followed during50 days. Various nutrients were measured.Results After the mineralization process, the best manurewhich released more nutrients was T4 with measured proportionsof N-NO2-, N-NO3-, N-NH3, P-PO43-, Ca2 ,Mg2 , K , and suspended matter being 0.06 ± 0.0,0.38 ± 0.1, 0.85 ± 0.1, 8.27 ± 0.9, 12.11 ± 0.8, 4.47 ±0.3, 3.02 ± 0.2, and 140.78 ± 18.6 mg/L, respectively.The highest content of phosphorus and nitrogen wasrecorded in T4 and T2, respectively. The principal componentanalysis showed a positive correlation betweenP-PO43-, Ca2 , Mg2 , MES, conductivity, and salinityduring mineralization.Conclusion Manure from rabbits fed by an improved dietwith P. maximum (T4) was recommended for agro-pisciculturalproduction system.
