It is important to understand nutrient budgets of aquaculture practices for efficiency of input resources and to utilize all output nutrient sources. The aim of the present study was to develop a nutrient budget for giant freshwater prawn (Macrobrachium rosenbergii) culture ponds. The study was conducted in farmer's ponds (0.25-0.5 ha) of Odisha, India, and the results showed that feed accounted 97 % total nitrogen (N), 98.7 % total phosphorus (P) and 90 % total organic carbon (OC), respectively. The harvested prawn accounted for recovery of 37 % N, 10 % P and 15 % OC, respectively. The N, P and OC accumulated in sediment were 52 %, 76 %, and 65 %, respectively. Nutrient loads in the effluents were 2.22 ± 0.66 kg inorganic N, 0.40 ± 0.15 kg P, and 21.01 ± 6.4 kg OC per ton of prawn production. The present study implicated that high nutrient values observed in both water and sediment provide important opportunities for nutrient reuse through pond sediment applications to croplands as an organic manure, as well as pond water irrigation to crops as a "liquid fertilizer". © 2014 Springer Science+Business Media New York.

Nutrient budget for shrimp (Penaeus monodon) culture was performed in ten culture ponds (0.4-1.0 ha) in Orissa, India, at stocking density of 10.0-22.10/m2. The average initial body weight of shrimps was 0.02 g. The culture period was for 4 months. Feed was the main input of nitrogen (N), phosphorus (P) and organic carbon (OC). The FCR varied from 1.35 to 1.75. At harvest time, the average weight of shrimps varied from 28 to 32 g. Total N, P and OC applied to these ponds through all the inputs ranged from 106.64 to 292.63, 23.17 to 57.55 kg and 763.10 to 1,831.20 kg per crop, respectively. Feed alone accounted for 94.43-95.03 % total N, 91.92-95.36 % total P and 80.33-92.48 % total OC, respectively. The harvest of shrimp accounted for recovery of 25.45-36.88 (av. 30.12) %, 10.07-12.94 (av. 11.16) % and 15.80-20.81 (av. 18.01) % of added N, P and OC, respectively. N, P and OC accumulated in sediment were 49.11, 64.07 and 64.82 %, respectively, of total nutrient retention in the culture system. Unaccounted N, P and OC were 13.29, 21.83 and 18.14 %, respectively, of the total nutrient retention in the system. N, P and OC outputs in the discharged water during harvest were 7.48, 2.94 and 2.03 %, respectively. © 2012 Springer Science+Business Media B.V.

A nutrient budget was quantified for six polyculture ponds of giant freshwater prawn (Macrobrachium rosenbergii) and Indian major carps (Catla catla, Labeo rohita, and Cirrhinus mrigala). The initial stocking size of prawn postlarva was 16.50 ± 0.54 mm with a body weight of 0.05 ± 0.001 g. Body weight of major carps was 9.0 ± 0.89 g. The duration of culture was 280 days. Feed accounted for 82% of total nitrogen (N), 93% of total phosphorus (P), and 95% of organic carbon (OC) inputs. Harvest of prawn and carps recovered 44% N, 1% P, and 19% OC. N, P, and OC accumulated in sediment were 47%, 73%, and 69%, respectively. Nutrient load in the harvest water was 0.67 ± 0.21 kg inorganic N, 0.15 ± 0.01 kg P, and 7.72 ± 0.62 kg OC per ton of Indian major carps and prawn.

The present study was conducted to determine the carbon (C) footprint of different aquaculture production systems in India. The total input (kg CE/ha) in different cultures, respectively, was 1, 811 to 4, 144 for scampi, 4, 417 to 5, 913 for polyculture, 4, 090 to 8, 873 for shrimp and 2, 417 to 2, 786 for carp. Of the total inputs, feed accounts for around 90% of carbon equivalent (CE), in all cultures. The output in different cultures, expressed on live weight basis (kg/ha) and on input basis (kg/kg), respectively, was 1, 280 to 3, 288 and 0.71 to 0.79 for scampi culture, 4, 639 to 5, 998 and 1.00 to 1.05 for polyculture, 2, 130 to 5, 436 and 0.52 to 0.61 for shrimp culture, 4, 100 to 4, 160 and 1.49 to 1.70 for carp culture. On the basis of output:input ratio, the carp (three species of Indian major carp) culture is more sustainable followed by polyculture (carp with scampi), scampi and shrimp culture, respectively. © IWA Publishing 2013.
