Understanding the phenomenon of shrinking fish and what it means for food supply
Fish are getting smaller, according to a global study over 60 years — with clear implications for global protein supply.
How to reduce antibiotic use in Chile, the Americas’ salmon-production giant
Cutting antibiotic use is one of the major sustainability priorities in global food production, and while aquaculture has taken steps along this road, there’s still a long way to go.
Sea bass farm in Italy hit by a rare outbreak of lactococcosis
Scientists have reported a case of lactococcosis, caused by the bacterium Lactococcus garvieae, at a sea bass farm in Italy — a rare development which has prompted questions over its origins and possible wider threat.
Probiotics help tilapia grow and fight disease, say scientists
Feeding Nile tilapia probiotics leads to improved health and performance, according to work analyzing research to date.
Some functional feeds may have trade-offs for salmon health — new study
There is a complex balance between the benefits and drawbacks of functional feeds for Atlantic salmon when fish are facing concurrent health threats, a Canadian study suggests.
Ensuring elite disease management during challenging time for Canada’s salmon farms
Salmon farming in Canada is facing some unprecedented challenges, but there is no sign of the industry letting its guard down when it comes to disease prevention.
One pathogen strain seems the main culprit in damaging salmonid disease
A distinct strain of the main fungus-like pathogen which causes saprolegniosis — thought to be responsible for around 10% of economic losses in the salmonid industry — looks likely to be responsible for the majority of outbreaks of the disease on Atlantic salmon fish farms.
Fishmeal substitute made from zooplankton could boost tilapia growth and health
A feed made from the zooplankton daphnia boosted growth rates of red tilapia fry when used as a partial replacement for fishmeal, but too much daphnia had the opposite effect.
Mollusk farms must prepare for more disease under climate change
Warmer seawater is creating perfect conditions for many mollusk pathogens to thrive, scientists have warned.
Research highlights risks of thermal delousing treatments for unhealthy salmon
Thermal sea lice treatments do not appear to cause increases in pathogens which threaten farmed salmon, but the risk of stress-related mortalities means that fish already suffering from disease should not undergo thermal sea lice treatments, according to Institute of Aquaculture researchers.
