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 ...

Understanding biofloc in aquaculture production systems (Part 1)
Since 2009, protein from aquaculture production has surpassed that of fisheries for the first time in history. Aquaculture is simply a water-based agriculture with a long history. It is an essential source of nutrition, as well as a source of income for large number of communities. Aquaculture is here to stay, despite opposition to aquaculture from segments of the NGO community and commercial ...

Aquaculture and sustainable development: a regulatory or governance system?
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. ...

Effects of different management regimes on mangrove ecosystem services in Java, Indonesia
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 ...

Biological water treatment in aquaculture by means of “Mutag BioChip™ RAS Process“
Aquaculture or fish farming means the artificial breeding and raising of aquatic creatures. They include fish as well as crustaceans and shellfish, which are raised and stocked under controlled conditions by using techniques and technologies offering an increased level of productivity which cannot be realized under natural conditions. Due to the increased demand for freshly caught fish and ...

Water budgets for freshwater fish ponds of Andhra Pradesh, Orissa and West Bengal, India
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 ...

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 ...

A prawn in the game - Case Study
The UK’s demand for king prawns is, apparently, insatiable. Most have travelled, frozen, 6,000 miles from the Far East and Central America leaving a massive carbon footprint, but Great British Prawns is changing that. The company opened its first sustainable king prawn farm in the Scottish village of Balfron, Stirlingshire, in the summer of 2019 and is now supplying fresh prawns to hotels ...

Sustainable Alternatives of Shrimp Aquaculture
Early Sustainable Aquaculture Aquaculture traces its roots back thousands of years. Local farmers and fishers have cultured fish, mollusks, and crustaceans for generations, using traditional methods and local ingenuity to improve their living conditions through low-intensity aquaculture. Though these systems produced low yields, production was sufficient to meet the needs of local residents. ...

Bio Films in Recirculating Aquaculture system
A biofilm is an assemblage of microbial cells that’s irreversibly related to a floor and enclosed in a matrix of normally polysaccharide material. It can also additionally shape on a extensive kind of surfaces, along with residing tissues, scientific devices, commercial or potable water device pipe or herbal aquatic systems. A well-assorted organism inclusive of algae, micro organism, ...

Pilot scale testing of advanced oxidation processes for degradation of geosmin and MIB in recirculated aquaculture
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 ...

Phosphatase activity and specific methanogenic activity in an anaerobic reactor treating sludge from a brackish recirculation aquaculture system
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 ...

Carbon footprint of aquaculture in eastern India
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 ...
