Model of an aquaponic system for minimised water, energy and nitrogen requirements

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 ...

Massive freshwater gains from producing food at sea

Water scarcity may be the most limiting factor to increasing world food production. Irrigation water is already overdrawn beyond sustainable levels and to increase reliance on rainfed agriculture is risky, even more so with climate change. However, to promote deliberate food production at sea, both fished and farmed, and both plant and animal, requires no freshwater or land. The thousands of ...

The treatment of (fish) ponds on an environmentally friendly manner with the usage of the LG Sonic case study

Aquaculture, or aqua farming, is the cultivation of aquatic organisms, such as fish or shrimps, in a controlled environment. Where this happens in a closed water container, algae may occur that pollute the water and may damage the organisms grown. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these. LG Sonic uses ...

Fishing for a Solution

As writer Rowan Jacobsen explores in our recent feature “Has Meat Met Its Match?,” animal agriculture’s hefty environmental footprint is creating interest in exploring ways to meet humans’ growing appetite for animal protein that extend beyond beef, chicken and pork. In some places, that ...

CO2 Removal and Stripping Column Ventilation Rate at Bell Aquaculture

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 ...

Ghana Fish Farming and Fish Feed Production

There are two main ways to obtain feed for fish farming in Ghana: locally produced feed and imported feed. However, fish feeds locally produced are in bad quality as most of them are not extruded. Imported feed is appropriately 30% more expensive than locally produced. So importation is not a quick fix. On average the costs for Tilapia farming in Ghana consist of 70% of the feed cost. Therefore, ...

ASM proven sonic wave technology remove filamentous algae of fishnets in a environmentally way!

Fish net cleaning is one of the biggest costs in marine aquaculture management is weed growth on fish cages and the labour and plant costs devoted to cleaning nets is significant. Considerable effort and research has been devoted by ASM to this particular challenge and recent technological advances have been applied. Also,diseases are easily spread among farmed fish due to the ...

Measurement of the amount of DissolvedOxygen

Dissolved Oxygen (DO) is the term used for the measurement of the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and waste water treatment, the level of DO must be kept high. For aquaculture if the DO level falls too low the fish will suffocate. In sewage treatment, bacteria decompose the solids. If the DO ...

Estimating preferences for non-market attributes of aquaculture and sustainable seafood production: methods and empirical applications

If aquaculture is to promote sustainable seafood production, the public must be willing to accept associated tradeoffs. Tradeoffs may include impacts on a variety of environmental and social attributes. Public preferences for aquaculture may differ according to type of operation, species, region, and other factors. Stated preference methods can assist policymakers in designing balanced, ...

Modern Project on Establishment of Fish Feed Production Plant

Fish Feed Plant Background & Necessity Along with the development of aquaculture, aquafeed industry has also made a quite fast progress, especially in virtue of continue advancement of breeding technology, the culturing mode has turned into intensive cultivation from extensive fish farming, which provides vast space for fish feed production. In line with the FAO (Food and Agriculture ...

Simulations of nutrient emissions from a net cage aquaculture system in a Brazilian bay

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 ...

Indonesia: Opportunity for shrimp aquaculture - Case Study

Great opportunities exist in shrimp culture in Indonesia due to land availability and ideal climate. Already, this country is one of the largest producers in the world. Many farmers use AIRE-O2® aerators as their 'aerator of choice' because the 'performance is better than the paddlewheel and the AIRE-O2® aerators keep the bottom of the ponds cleaner,' said the manager at this farm. The P. ...

Cultivation of microalgae (<italic>Oscillatoria okeni</italic> and <italic>Chlorella vulgaris</italic>) using tilapia-pond effluent and a comparison of their biomass removal efficiency

Cultivation of microalgae (Oscillatoria okeni and Chlorella vulgaris) using tilapia-pond effluent and a comparison of their biomass removal efficiency

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 ...

The most threatened ecosystem you’ve never heard of

What covers up to 600,000 square kilometers (230,000 square miles) of Earth’s surface, provides benefits worth an estimated US$570 billion each year, and is rapidly being lost due to human activity? If you have not a clue, you’re far from alone. Scientists who study the underwater feature known as a seagrass meadow call it a “ ...

Development of new methods to assess invertebrate immunology and immunotoxicology in aquaculture: oysters and lobsters as examples

In order to support healthy aquaculture, we developed assays to assess immune functions and their susceptibility to environmental conditions or toxicants. Flow cytometry allowed the rapid and quantitative analysis of oyster and lobster cell subpopulations and their functions (phagocytosis, peroxide production, natural killer cell-like activity and apoptosis). We demonstrated experimentally that ...

Bioeconomic modelling and salmon aquaculture: an overview of the literature

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 ...
