Early-stage indicators of the African catfish Clarias gariepinus (Burchell) (egg fertilization and hatching rates, larval survival rate and time to hatch) were assessed in aqueous solutions of NPK 15-15-15 and layer manure. Recommended use rates (RUR) of NPK 15-15-15 and layer manure have volume-equivalent of 15 mg/L and 28 mg/L respectively. Solutions containing *0.7RUR, *1.0RUR and *1.5RUR dilutions were used as treatments within-fertilizer. There were significant differences in pH, dissolved oxygen (DO), total hardness and total metal levels in treatments of NPK (p < 0.0001) and layer manure (p < 0.0001). Fertilization, hatching rate and larval survival were significantly lower while incubation was significantly longer in treatments of NPK (p < 0.001) and layer manure (p < 0.0001) in comparison with control. In NPK treatments, the indicators correlated with pH (r −0.96 to −0.98, p < 0.0001), with 99.1%-99.6% (p < 0.0001) of changes of indicators explained by pH. In manure treatments, the indicators correlated with DO and pH (r = 0.92 to 0.998) (p < 0.0001), with 98.1%-99.7% (p < 0.0001) of changes explained by DO and pH. NPK and layer manure have deleterious effect on C. gariepinus early stages.The toxicity and explanatory physico-chemical parameters should be considered when the fertilizers target aquatic productivity.

A study was carried out to evaluate the growth and production performances of stinging catfish (Heteropneustes fossilis) and rabbit (Oryctolagus cuniculus) under two treatments such as T1 (shing-rabbit integrated system) and T2 (shing monoculture) in farmers’ pond. Twelve ponds from two villages such as Sutiakhali and Salakandi under Mymensingh sadar upazila were selected for the study. The average pond size was 5.5±0.23decimal with a stocking density of 600 shing dec-1. The ponds were only fertilized with rabbit dung except at the time of pond preparationat a rate of 1 kg dec-1. Various environmental parameters such as temperature (oC), transparency (cm), PH, dissolve oxygen (mg L-1), PO4-P (mg L-1), NO3-N (mg L-1), NO2-N (mg L-1), NH3-N (mg L-1), chlorophyll and alkalinity (mg L-1) were monitored once in a week. The parameters were found to vary little from pond to pond and most of the parameters were within the suitable range for freshwater aquaculture in Bangladesh. The highest survival rate of fish was 95.36 ± 0.15 % in treatment T1 and the lowest was 90.39 ± 0.10 % in treatment T2. The survival rates of fish were not significantly different among the treatments (P > 0.05). The production of fish in T1 and T2 treatment was 25.36 and 20.43 kg dec-1, respectively. Daily growth of shing in two treatments were 1.95 ± 0.01 and 1.88 ± 0.01 % respectively. The study revealed that integrated shing-rabbit would be highly profitable using improve extensive culture system in the rural household ponds through effectively reducing the use of pond fertilizer and fish feeding cost.
