Nepal sees food security potential in aquaponics, a combination of aquaculture and hydroponics.
Aquaculture efficiently farms fish species while hydroponics ensures controlled use of water and nutrients in plant cultivation.
In aquaponics, water saturated with nutrient-rich fish excreta from aquaculture tanks is used in plant breeding before being circulated...
Aquaponics is the symbiotic cultivation of plants and aquatic animals in a recirculating environment. The systems rely on the relationship between the aquatic animals and the plants to maintain the environment. Water is only added to replace water loss from absorption by the plants, evaporation into the air, or the removal of biomass from the system. Aquaponic systems vary in size from small indoor units to large commercial units. They can use fresh or salt water depending on the type of...
1. Introduction
Diversifying categories of the world renowned scientist have been deeply implemented in researching the uprising global threat of the climatic changes on the existence of all living creatures on the planet earth. Climatic changes have been known for a while for their rious impact on the biology, fecundity, growth and biodiversity of aquatic, terrestrial and aerial animals [1]....
St Paul, Minn. - Fitted with electrofishing equipment, the boat eased into the cattails along North St. Paul's Casey Lake, two University of Minnesota technicians standing at the bow with dip nets ready to scoop up stunned common carp.
In short order, they did, plopping them into a pail so that small radio tags could be inserted into the largest ones, enabling researchers to track their movements.

ABSTRACT An experiment was carried out for 6 months on rearing Nile tilapia and silver carp, whether under monoculture or polyculture at different stocking densities. Four floating net cages (10 x 10 x 3 m) were used. The obtained results revealed that the best treatment was the monoculture of all males mono-sex Nile tilapia (10000 fish of 10g each/cage) followed by that of polyculture (5000 tilapia of 10g with 750...
Technological advances, which focus on both cost savings in the form of reduced down time as well as optimal flexibility in terms of capacity and quality, have been in demand by the industry. The physical quality of fish feed product can be defined by: * Density * Shape and size * Uniformity * Durability * Water stability The nutritional quality of fish feed can be defined as: * Recovery of essential amino acids and specific...
Western consumers have, due to enhanced education and increased access to scientific and media services, become more sophisticated in their purchasing decisions. In an age of bioterrorist threats, outbreaks of unusual zoonoses (e.g., transmissible bovine spongiform encephalitis, severe acute respiratory syndrome), increasing health concerns related to chemical contaminants (Hites et al., 2004) and the advent of genetically modified organisms, more attention than ever is being given...

Canada Canadian aquaculture production has doubled from 82,487 tonnes 10 years ago to 170,172 tonnes in 2007. The corresponding value increased from CA$392 million to CA$846 million. Production had peaked in 2002, reaching 171,803 tonnes, but fell again in the following years when the salmon production was affected by an infectious disease. Although production rebounded after three years, it still hovers around the 2002 level (see...
Among intensively cultivated aquatic species, shrimp has one of the highest values and is the most important fishery commodity traded. In 2008, the FAO estimated that world production of shrimp under aquaculture and capture was about six million tonnes. Of this, an estimated 60 percent was traded, bringing in over US$11 billion in export revenue for producing countries. But close on the heels of shrimp's enormous economic benefit have been...
Tests prove the effect of potassium diformate on the quality of fish under tropical conditions Almost one-third of the world fish harvest is not used for direct human consumption, but is converted into fish meal or fish oil for further application in animal feed. Of the 75 million tons of fish about 25 million tonnes is therefore handled and processed in other ways than fresh, frozen, smoked or canned (Balios, 2003). ...

Fishform Plus - a liquid blend of potassium diformate, antioxidant and corrosion inhibitor - and promoted to prolong freshness of trawled trash fish caught for fishmeal production, has been tested in a large scale experiment by ADDCON experts onboard during 10 days trawl operation in the Gulf of Thailand in July 2009 (Figure 1). The catch consisted mainly of pelagic and benthic species, such as anchovies ( Stolephorus sp. ), croakers ( Pennahia sp. ), scads ( Seraloides...
The latest World Aquaculture Society Meeting took place last September in Veracruz, México. Despite the number of presentations, the organizers succeeded in separating the sessions in a logical way (trying not to have two sessions on the same subject, at the same time, in different rooms). The main subjects covered during the meeting where: Feedstuffs, Feed Additives & Functional Foods, Food Safety and Security, Shrimp (Breeding, Nutrition, Production and Health), Tilapia,...
