In 2010, 40.5 percent of world fish production was marketed in live, fresh or chilled forms and 45.9 per cent processed in frozen, cured or otherwise prepared forms for direct human consumption, according to the FAO's "The State of World Fisheries and Aquacult…
Food quality is increasingly becoming a global concept as suppliers and retailers become larger and fewer. Food should be responsibly sourced, safe and traceable to the farm. In addition, the ethical aspects concerning food production, such as protection of th…
There have been an increasing number of infections in fish associated with different species of Chryseobacterium, being considered potentially emerging pathogens. Nevertheless the knowledge of the diversity of species associated with fish disease is partial du…
Overall global capture fisheries production, as derived from the FAO capture database, continues to remain stable. This does not mean that there are no changes in catch trends by country, fishing area or species, which indeed do vary significantly throughout t…
Farmed salmon smolts become more robust and more likely to survive if they undergo optimal aerobic exercise training prior to sea transfer. This was the main message from Chilean Vicente Castro in his doctoral defense in Norway recently.
It is widely understood that each fish species has an optimum temperature range and will lose appetite and grow more slowly when water temperatures go much above that range. Until recently the physical effects on the fish leading to these symptoms were not ful…
The decreasing availability of fishmeal and fish oil for marine ingredients will force the industry to depend more heavily on by-products for fish feed, said Johnathon Shepherd, past Director General for the International Fishmeal and Fishoil Organisation (IFF…
Climate change is a reality and it will affect aquaculture. Sena S. De Silva of Deakin University, Australia discusses the challenges that climate change poses for aquaculture.
This article, from the FAO's "The State of World Fisheries and Aquaculture 2012" report, looks at the history and importance of how rice and fish farming can be combined, and also how it promotes enhanced food production and wealth.
Salmon exposed to algal-produced neurotoxins show changes in both their brain activity and general behaviour. It has also been found that very small doses of these toxins can have an affect on how salmon relate to other fish.
Sturgeon hatcheries play an important role in the rehabilitation of the sturgeon stocks in the Caspian Sea and elsewhere. This FAO report gives guidelines for sturgeon hatchery practices and management.
G. salaris is a tiny creature measuring less than half a millimetre in length. It uses its tiny claws to attach itself to the skin ofyoung salmon, which it then eats. G. salaris breeds prolifically and a young salmon may be host to up to 10,000 individual spec…
Temperature changes can alter the growth, survival and feed conversion of cultured Pacific white shrimp, Litopenaeus vannamei. To examine the effects of temperature on these performance factors, Dr Chalor Limsuwan, Kasetsart University, and Dr Carlos A. Ching,…
Imaging with X-rays and nuclear magnetic resonance imaging (NMR/MRI) are technologies normally associated with hi-tech materials science or medical examinations; now Skretting is using them to examine the humble fish feed pellet.
As part of the FAO 2012 report 'The state of world fisheries and aquaculture', this article looks at the barriers to achieving low impact fuel efficient fishing in today's society.
Atmospheric gases naturally diffuse between air and water to reach an equilibrium of pressure. Gases dissolve in the blood of fish and shrimp, and equilibrate with gases in the animails water. When water is suddenly warmed, gas bubbles can form in the blood of…
Transmission of infection from neighbouring fish farms is the main way that the viral disease Infectious Salmon Anaemia (ISA) spreads during epidemics. This is the key conclusion of Trude Lyngstad's doctoral research.
Due to the build up of bacteria and viruses in bivalves from filter-feeding, bivalves can be harmful to humans when ingested. The different factors affecting the microbial quality of shellfish is therefore analysed in a study by Carlos Campos, Ron Lee, Simon K…
Researchers from the USDA ERS have explored whether US consumers adjusted their purchases of shrimp in response to the 2005 country-of-origin labels (COOL) requirements for seafood. Findings show that consumers were not responsive to the new country-of-origin …
This article by Peter S. Rand and B. A. Berejikian et al, from the Wild Salmon Center in Portland, Oregon, US, and the NOAA Northwest Fisheries Science Center, looks at the ecological interactions between wild and hatchery salmonids.
This article from the FAO's 'The State of World Fisheries and Aquaculture 2012 Report' looks at the acceptance of women in aquaculture and the promotion of women in aquaculture to help develop education, training and economic prospects.
The 2012 benchmark stock assessment and peer review have concluded that the American eel population is depleted in US waters. The stock is at or near historically low levels due to a combination of historical overfishing, habitat loss, food web alterations, pr…
