Bioeconomic models can be used to assist producers and decision-makers in identifying optimal production system designs, operation management strategies, and alternative development and policy approaches. This paper reviews the literature on bioeconomic modelling in aquaculture since 1993 and builds on an earlier article by Leung (1994) which examines this literature for the 1974-1993 period. In ...

Monitoring and controlling CO2 level in Recirculating Aquaculture Systems (RAS) is crucial not only for fish health but it is used increasingly for efficient management. Under supervision of Steve Summerfelt, a joint project has studied costs savings with optimizing ventilation based on CO2 continuous monitoring. The CO2 probe used in that project came from ...

The water budgets for some aquaculture systems in three states viz. Andhra Pradesh, Orissa and West Bengal were determined in the present study. The average evaporation and seepage loss from the aquaculture ponds throughout the year in Cuttack, Kendrapara, Jajpur, and Puri districts of Orissa were 164 ± 8.3 and 73 ± 16.5 cm, respectively; 152 ± 10 and 90 ± 16 cm, respectively, in South and ...

The presence of geosmin and 2-methylisoborneol (MIB) in recirculated aquaculture systems has a significant negative impact on the fish production due to poor flavour quality of produced fish and increased risk of rejection by fish processers. Advanced Oxidation Processes has a high potential for removal of geosmin and MIB in water and in this study UV/H2O2 and UV/O3 has been tested in pilot scale ...

Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to ...

AquaLifeNet partnered with JAK International to bring the latest biological filtration technology to a Catfish farm in Mymensingh, Bangladesh. The team installed a Biofishency Mini Re-circulation Aquaculture System (Mini RAS) to treat and re-circulate the water. Biofishency’s project partner, Upgrade Solutions, provided eight corrugated metal fish tanks with PVC liners ...

The uptake of dissolved nutrients by microalgae is the primary way to remove nitrogen in aquaculture systems. Many authors have studied the use of microalgae to treat wastewater from aquaculture. However, excessive microalgae accumulation may cause high levels of organic matter and suspended solids in the final effluent. Thus, an efficient way to remove excess algae is needed in wastewater ...

Anaerobic treatment of high salinity sludge from marine/brackish recirculation aquaculture systems is potentially limited by inhibition of enzymatic activities and cell lysis resulting from high osmotic pressures. To further address these limitations the following investigations were conducted: effect of salinity on phosphatase activity (PA), soluble microbial products (SMP) production, and ...

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 ...

Governance is defined as a process allowing actors to contextualise the regulatory system and, as a result, to transform sustainable development (SD) into an instrument of action. It will be all the easier for actors to familiarise themselves with SD and its implementation measures if these measures are similar to their representation on SD and its consequences on their activity and social life. ...

This new report, published by Wageningen University and Wetlands International, seeks to fill a significant gap in mangrove ecosystem service estimates. While several studies have sought to measure and value the ecosystem services provided by mangrove ecosystems in general, this new piece of research has for the first time conducted separate evaluations for zones that are characterised by ...

AquaLifeNet has helped the Sultan Fish Farm in India to upgrade and expand their fish farming operation to produce a more valuable crop using our unique aquaculture system. The Sultan Farm is located in the town of Butana in the Haryana district north of Delhi. They had been growing an annual crop of 15-20 tonnes of carp fish in earth ponds, but they decided to expand and ...

Water and nutrient savings can be established by coupling water streams between interacting processes. Wastewater from production processes contains nutrients like nitrogen (N), which can and should be recycled in order to meet future regulatory discharge demands. Optimisation of interacting water systems is a complex task. An effective way of understanding, analysing and optimising such ...

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be "in the black", let alone grow annually by 10-20%. Just to get started, a corporation must at least have the funding, the right location with good weather, good access to water (the list goes on) and most importantly, the right people to manage day-to-day ...
