The annual production survey of fish farms in Scotland for 2011 was carried out by Marine Scotland Science (MSS). This survey collates annual production data from Scottish fin fish farm sites operated by authorised aquaculture production businesses.
Worldwide, more than 18 million persons were infected with fish-borne zoonotic trematodes in 2002. To evaluate the effectiveness of interventions for reducing prevalence and intensity of fish-borne zoonotic trematode infections in juvenile fish, authors from t…
The toxins from blue-green algae pose a threat to animal health and potentially to consumers if they are present in farmed product. Culture animals that ingest these toxins may not die, but can be weakened, increasing their susceptibility to pathogens. Killing…

Researchers based in Norway have successfully fractionated wheat distillers dried grains and solubles (WDDGS) to improve its nutritional value for rainbow trout.
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.
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…
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…
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.
