“…But they found consumptive water use (CWU‐6.38–5.61 m 3 /kg) to be lower in the higher density and attributed such reduction to the increased yield. In semi‐intensive IMC polyculture system, Sharma, Mohapatra, Das, Sarkar, and Chand () have estimated TWU to be 10.3 m 3 /kg fish out of which 7.6 m 3 /kg was the system associated requirement, thereby the CWU calculated to be 2.7 m 3 /kg fish. Boyd () has reported a CWU to range between 4 and 8 m 3 /kg fish in earthen ponds.…”

One year grow‐out evaluation of four cropping patterns of carps, viz. control: single stock single harvest (SSSH); T‐1:intercrop of minor carps and Indian major carps (IMC); T‐2:single stock multiple harvests (SSMH); and T‐3:multiple stock multiple harvests (MSMH) was conducted in eight earthen ponds (0.09 ha each). Ponds were stocked with three IMCs (catla, rohu and mrigal) at 1:1:1 ratio at 10,000 fingerlings/ha combined density. T‐1 was additionally stocked with 10,000 fingerlings/ha of minor carps (Puntius gonionotus, Labeo fimbriatus and Puntius sarana), while T‐2 with additional 10,000 fingerlings/ha of the IMC. Periodic removal of partial biomass ensured prevalence of better water quality in treatments (higher water pH, higher dissolved oxygen and reduced inorganic nutrients). It helped to improve fish growth as average harvested weight of rohu and mrigal remained similar in treatments despite the presence of greater inter‐ and intraspecific competitions in intercrop and SSMH, respectively, and periodic stocking of younger juveniles in MSMH. Catla showed significantly higher growth in MSMH. The biomass yield in intercrop, SSMH and MSMH were 21%, 17% and 24% higher than SSSH, but the respective net incomes were 32.9, 21.3 and 56.5% higher. Partial harvest also helped reducing FCR in the order T‐3

“…Selain itu, banyak sedikitnya volume air tambak juga sangat dipengaruhi oleh proses penggunaan air pada proses water budget. Water budget sangat dipengaruhi oleh tingkat penggunaan air dari proses keluar-masuk air selama periode budidaya [38]. Proses keluar masuk air pada sistem budidaya itu sendiri dapat berasal dari proses presipitasi, limpasan, dan proses pergantian air, sedangkan air keluar dapat berasal dari proses evaporasi, rembesan, dan siphon [8,27].…”

Efektifitas penggunaan kincir air selama masa periode blind feeding budidaya intensif udang vannamei (Litopenaeus vannamei) merupakan salah satu kegiatan penting yang harus diperhatikan demi kelangsungan siklus budidaya yang stabil. Tujuan dari penelitian ini adalah untuk mengetahui tingkat transfer oksigen oleh kincir air serta hubunganya terhadap parameter harian kualitas air tambak. Peneltian ini dilakukan dengan konsep desain kausal ex-post facto selama 30 hari awal masa budidaya intensif udang vannamei (Litopenaeus vannamei) atau selama periode blind feeding budidaya. Hasil penelitian menunjukan bahwa nilai parameter kualitas air di lokasi tambak masih sesuai ambang batas. Sedangkan tingkat transfer oksigen oleh kincir air bersifat fluktuatif selama 30 hari masa pengamatan. Sementara dari hasil uji korelasi menunjukan bahwa hanya variabel suhu dan salinitas air memiliki keeratan hubungan yang kuat terhadap proses transfer oksigen oleh kincir. Sehingga dapat disimpulkan bahwa fluktuasi tingkat transfer oksigen oleh kincir air sangat dipengaruhi oleh kondisi suhu dan salinitas air tambak.

“…Exchanges of large water volumes have typically been used to control nutrient levels in grow-out ponds (Boyd & Tucker 1998), but as resource limitations increase, the use of and energy required to exchange large volumes of water is unsustainable, providing impetus to improve water productivity through wastewater treatment and reuse (Sharma et al 2013). Furthermore, the ex change of large water volumes dilutes wastewater and makes the removal of solids difficult, especially in saline systems where settling of solids is reduced (Mesquita et al 2011).…”

Land-based aquaculture is an integral part of global aquaculture production for fishes (28.8 million t), molluscs (13.1 million t) and crustaceans (5.0 million t; FAO 2010, Hall et al. 2011. The majority of landbased systems which support the intensive culture of fresh, brackish and marine water organisms do so through the addition of high-protein feeds to sustain the rapid growth of intensively farmed animals ABSTRACT: Settlement ponds are used to remove particulate and dissolved nutrients in Australian land-based aquaculture wastewater. At best, marine and brackish water settlement ponds reduce total suspended solids by 60%, but their efficiency is inconsistent. Functional improvements to nutrient removal systems are essential to provide uniform and predictable treatment of flow-through aquaculture wastewater. Furthermore, environmental regulation of discharge from intensive systems in Australia is increasing, providing the impetus to upgrade rudimentary singlestep settlement pond systems. We characterise technologies used for land-based aquaculture wastewater treatment prior to discharge from shrimp systems in Australia. We identify opportunities to integrate technologies developed for the treatment of municipal wastewaters and intensive recirculating aquaculture systems, and use these to develop a model system for intensive shrimp farm wastewater. The first stage is the reduction of solids through the use of deep anaerobic ponds, which are tailored to dilute saline wastewater. Non-settled colloidal and supracolloidal solids can subsequently be removed through trapping in a sand bed filter and biological transformation to dissolved inorganic nitrogen or N 2 . The resulting dissolved nutrients can be treated in a 3-stage algal treatment system by assimilation into harvestable biomass, and finally constructed wetlands polish wastewater through further trapping of particulates, and transformation of dissolved nitrogen. Given that upgrading wastewater treatment facilities is costly, we highlight options that have the potential to offset nutrient treatment costs, such as the use of algal biomass for food or energy products, and the recycling of nitrogen and phosphorus via pyrolysis creating products such as biochar and biofuel.
