Shinshu salmon is promoted as a food typical of the mountainous prefecture of Nagano, which is aiming to capitalize on the popularity of salmon in Japan. 

Study uses a simple multispectral imaging system to assess various spoilage and predict freshness in rainbow trout fillets during storage for 12 days. 

Study quantifies temporal changes of selected fatty acids from six fish species subjected to two handling and three storage methods compared to samples that were processed immediately. 

Genetic selection research finds that vegetarian versions of rainbow trout can be raised on a cost-effective and fully plant-based diet. 

This study evaluated the effects of replacing fishmeal and fish oil with a plant-based diet in juvenile and on-growing rainbow trout from first-feeding. 

Harry Hamlin-Wright is a fish vet. It’s a career choice that gets strange looks but offers him varied and interesting work. See the world of aquatic animal health and welfare through a fresh set of eyes in a new Advocate series on aquaculture jobs. 

The Global Aquaculture Alliance's annual GOAL conference, held this October in Dublin, Ireland, offers attendees a unique learning experience. This photo slide show offers a sneak peek at the pre-conference field trip sites: a trout farm in Woodenbridge and an oyster farm in Dungarvan. 

Canada and the United States may be friendly neighbors, but when it comes to aquaculture, the bordering countries take vastly different approaches to aquaculture in the Great Lakes. 

Cleaning is part of the daily management to ensure adequate rearing conditions, but additional water treatment is occasionally required to further improve the water quality. A disinfectant like sodium percarbonate can reduce the bacterial load. 

Los fabricantes de alimentos acuícolas y proveedores de ingredientes alternativos para alimentos de todo el mundo se reunieron en Silicon Valley para el F3, el concurso de Alimentos sin Pescado (Fish Free Feed). En el centro de la innovación, las soluciones a un problema global estaban en plena pantalla. 

Aquafeed manufacturers and alternative feed ingredient suppliers from all over the world gathered in Silicon Valley for F3, the Fish Free Feed contest. In the hub of innovation, solutions to a global problem were on full display. 

India has a small trout farming industry in the Himalayan and Southern Peninsula areas. Even though current annual production is only a few hundred tons, the country has many areas that, although geographically difficult to work in, also offer excellent, very large habitats and conditions for trout culture. 

Quantification of fish behavior is complex and depends on the experimental setup and biomarkers applied. A simple method was tested to quantify locomotor behavior to evaluate the effects of simulated water treatment scenarios using peracetic acid. 

Various additives, many of plant origin, have been explored to replace the use of antibiotics in aquafeed. The authors compared the performance of rainbow trout fed diets containing oxytetracycline or mineral additives yellow loess and Song-Gang stone powder. 

The use of larger and deeper tanks can reduce building, labor and other aquaculture production costs. However, the ability to grade and transfer large numbers of fish is more challenging when using large tanks. In a comparison of the effectiveness of a purse seine and a hinged clamshell to crowd fish in large tanks, the latter was easier to control and less stressful to salmonids. With a slotted bar rack in a side panel of the clamshell crowder, fish were simultaneously graded in size.
