Realizing economic benefits from selective breeding
Although not universally practiced, the potential benefits of selective breeding in aquaculture outweigh all other options for improving animal performance. The genetic potential of aquaculture animals is plastic and can be improved over a relatively short timeframe.

Feed study examines effects of fishmeal storage
A study investigated the effects of storage temperature and duration on the quality of finished fishmeal fed to juvenile shrimp. Diets with 15 percent fishmeal were stored at 4 or 30 degrees-C for six months or 12 months.

Salmon’s position among European consumers
In a survey, 500 consumers from the United Kingdom, Russia, France, Germany and Sweden rated salmon second overall to chicken and ahead of pork and beef. Salmon scored high in all countries for healthiness.

Digestibility of fishery byproducts tested
A study of shrimp feeding demonstrated the digestibility of byproducts prepared from salmon livers, salmon milt, black cod viscera and arrowtooth heads and viscera from Alaskan fisheries processing plants.

Norwegian salmon smolt farms embracing RAS to raise production
Smolt production in Norwegian hatcheries will likely increase during the next decade to answer salmon grow-out needs. Farmers are converting existing flow-through systems to partially or fully incorporate recirculation technologies.

A brief look at genetically modified salmon
If approved by FDA, fast-growing genetically modified salmon will provide a safe and nutritious product similar to other farmed Atlantic salmon.

Developing a breeding program for Tasmanian salmon
A research partnership focused on Atlantic salmon selective breeding aims to improve growth and resistance to amoebic gill disease in Tasmanian salmon.

Innovative techniques achieve more cost-efficient salmon selective breeding
Successful non-invasive predictions of pigment and fat levels in whole salmon were demonstrated by the authors using visible and near infrared spectroscopy to study how these traits vary genetically during growth.

Chile’s salmon industry addresses health crises
Environmental and fish health problems have affected Chile’s salmon farmers since 2004. As production ramped up, 2006 saw an increase in sea lice that reduced output. In 2007, infectious salmon anemia spread across the farming region and quickly cut production.

Better to eat – farmed or wild salmon?
There is a widely promoted misconception that eating wild-caught fish is better for the oceans than eating farmed seafood. On a global basis, however, sustainably farmed fish may represent 60 times more efficient use of anchovies and other baitfish resources than wild fish.

New Norwegian RAS farm produces salmon smolts
The Fjordsmolt RAS farm applies a relatively simple, low-cost design to produce millions of salmon smolts per year in fiberglass tanks.

Ultrasound technology controls algae, biofilm growth
Ultrasound offers a low-impact alternative to chemical treatments for unwanted algae, like chlorophyll a, and biofilms in aquaculture.

Fish vaccination: Success with salmon expanding
Vaccination combined with good disease management can improve fish survival, improve feed conversion, reduce costs and secure predictable production.

Quality parameters in farmed Atlantic salmon
Studies have identified changes in the quality parameters of farmed Atlantic salmon and wild salmon that reflect changes in the animals’ life cycles, diets and environments.
