Could nanobubbles really revolutionize aquaculture?
Research is showing that nanobubble technologies can dramatically reduce disease risks on fish farms and potentially curb the need for antibiotics.
Algal oil shows promise as fish-oil substitute in feed for young salmon
Algal oil can replace fish oil in the feed of farmed Atlantic salmon parr without affecting their growth or ability to transition to seawater.
Mediterranean heatwaves putting farmed finfish under strain
The welfare of farmed seabream and sea bass in the Mediterranean is threatened by marine heatwaves, which are becoming increasingly frequent in the region.
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.
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.
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.
Yeast could aid shift away from fish-based diets in rainbow trout aquaculture
Torula yeast could be a promising option for inclusion in non-fishmeal feeds, with scientists finding links to production and immune improvements in a study using rainbow trout.
