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 ...

Fish farming at Kontiolahti
At Kontiolahti Fish farm the cuttings of salmon, trout and rainbow trout are cultivated to juveniles. Spawn is hatched and the juveniles of 0+ age-class are farmed inside. The older juveniles are farmed outside in surface basins. The water flow is 100-170 l/s depending on the season. Situation in the beginning The oxygen rate of the becoming water to the farm was not enough time to time, only ...

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 exploration is going underwater. Aquaculture, or fish farming, is the fastest growing ...

Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment
Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

Salmon lice and how to contain them
Over the past few years, the problem of parasitic lice spreading on farmed salmon has been increasing at an alarming rate. We are now seeing situations like last year where lice killed thousands of tonnes of farmed fish, caused skin lesions and secondary infections in millions more, and cost the Scottish industry alone around £300m in trying to control them. Here at Inciner8 we have been ...

Krill as a Taste Attractant - Case Study
Both fish and crustaceans live in an immersed aquatic environment, where their chemioperceptive system receives permanent stimulation by soluble compounds. These substances are usually of low molecular weight, non-volatile and most of them contain nitrogen (amino acids, nucleotides, etc.). These compounds stimulate the chemioperception of the animal (taste and smell), and its behavior (feeding ...

How to make fish feed pellet
Manufactured feeds is produced by feed pellet machine ,which is an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish. The feeds, in the form of granules or pellets, provide the nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential. The nutritional content of feed pellet can not ...

Chile Mandates Real-time Environmental Monitoring at Salmon Farms
Ocean-based fish farms in Chile have been ordered by Chilean officials to start monitoring environmental conditions in and around their pens in real time and immediately transmit the data to government environmental agencies. According to the August regulation from the Superintendencia de Medioambiente (SMA), ocean-based aquaculture sites will need to monitor water conditions for dissolved ...

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 ...

Transgenic fish are ready for us. Are we ready for them?
After decades of regulatory and legal challenges, AquaBounty aims to bring genetically engineered salmon to U.S. and Canadian markets next year. On a hill above the cold waters around Prince Edward Island, technicians painstakingly create fertilized Atlantic salmon eggs that include growth-enhancing DNA from two other fish species. The eggs will be shipped to ponds in the high rainforest of ...

Overfishing Threatens Critical Link in the Food Chain
The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten ...

How do I start a home based fishing farm business?
Why Start a Fish Farming Business? Fish is a delicious and nutritious source of protein, rich in nutrients such as omega-3 fatty acids, which improve our heart health and lower blood cholesterol. Farmed fish play an important role in meeting global protein needs. The rise of fish in the home today opens up many lucrative opportunities. Home-raised fish can easily be sold nearby or around ...

Does one of the world’s most abundant animals need protection from our appetite?
As demand grows and habitat disappears, scientists ponder tighter controls on the Antarctic krill harvest. Barely longer than your thumb, weighing under an ounce and nearly translucent, delicate crustaceans known as krill are vital to ocean ecosystems around the world. In the waters that encircle Antarctica, krill are an essential food source for penguins, baleen and blue whales (which can eat ...

How Profitable Is The Fish Farming Business
Fish farming usually involves raising a variety of aquatic animals, such as fish, mollusks, shrimp, etc., in any enclosure such as a tank or pond. Today, the demand for fish and fish products is growing because of the health benefits of their overall demand for meat and meat products. For one thing, fish is a very healthy source of protein and fat. Noted: Fish feed extruder is the dispensable ...
