  • Open sea-based Aquaculture case study

    Salmon farming is a multi-billion dollar global industry facing considerable difficulties posed by growing pressure from environmental regulatory bodies. Because marine organisms grow on and “foul” synthetic nets, oxygen available to fish is reduced and infectious diseases and parasites can spread among the fish. A test to study the reduction of fouling formation on netting of fish ...

  • 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 ...

  • A new reactor for denitrification and micro-particle removal in recirculated aquaculture systems

    A ‘membrane-denitrification’ reactor (MDR) was developed and tested in a semi-technical recirculation aquaculture system in comparison to a double – without MDR – as reference system. The MDR consisted of a reactor with an ultrafiltration membrane unit for removal of micro-particles (e.g. sludge flocs, bacteria and parasites). Specific carrier material provided surfaces for biofilm growth in a ...

  • Benzoylurea pesticides used as veterinary medicines in aquaculture: Risks and developmental effects on non‐target crustaceans

    Diflubenzuron and teflubenzuron are benzoylureas that are used in aquaculture to control sea lice. Flubenzurons have low toxicity to many marine species such as fish and algae, but by their nature are likely to have significant adverse effects on non‐target species such as crustaceans and amphipods. Although the exact mechanism of toxicity is not known, these compounds are thought to inhibit ...

  • 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 ...

  • Mangrove Capital

    This paper introduces Mangrove Capital; a programme conceived by Wetlands International and partner organisations, that aims to bring the values of mangroves to the fore and provide the knowledge and tools necessary for the improved management of mangrove forests. The project will enable governments, private sector organisations and local communities in Indonesia to manage mangroves, so that they ...

  • Animation: restoring eroded coast Java by Building with Nature

    Northern Java's coasts suffer from severe erosion. In one decade, some coastal areas have retreated by three kilometres. Developmnet of coastal infrastructure and aquaculture went hand in hand with the removal of protective mangrove forests and the disturbance of sediment flows towards the coast and floodplains. Replanting of mangroves has not been successful, as the sediment balance is too ...

  • Sea water treatment for shrimp farming - Case Study

    Global demand for seafood remains high, yet farming shrimps in aquaculture is a tricky business. Disinfection and desalination systems significantly improve the water quality in the breeding tanks, thereby improving the shrimp survival rate. Task Aquaculture - a growth market Shrimps are a popular delicacy, especially in Europe and the USA. According to the ...

  • 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 ...

  • Development of a Bioaccumulation Model For Herbicides in Ulva and Clams

    Coastal lagoons are shallow water ecosystems characterised by high biodiversity and primary and secondary production, and with an elevated number of different habitats. These habitats have a key role as nursery and rest areas for a great number of marine species and birds. During the last decades these ecosystems have been exposed tomany anthropogenic pressures (urban, domestic, agricultural ...

  • Catfish Feed Production Formulation & Process

    As is known to all, catfish has quite high nutritional value due to its good taste, delicate meat quality and its better dietary therapy function for those ill nourished people. With the sweet flavor and warm in property, catfish is in favor of urinating and treating edema, becoming good item to promote lactation and essential food material ...

  • Towards climate-responsible peatlands management

    Peatlands are lands with a naturally accumulated peat layer at their surface. They are found all over the world and come in many forms, display many different characteristics and are used in many different ways. Even though peatlands extend over a relatively small portion of the earth’s land surface, they hold a large pool of carbon. There is no universal definition of peatlands. For the ...

  • U.S. Farm-Raised Finfish and Shellfish

    Seafood has long been recognized as an important component of a healthy diet. Seafood contains high quality, complete protein and an important array of nutrients, while it is low in calories, cholesterol, and saturated fats. The health benefits of omega-3 fatty acids found primarily in fish have been clearly documented. U.S. farm-raised seafood is an important center of the plate choice that can ...
