Sub-Saharan Africa's limited aquaculture supply creates an excellent opportunity for Kenya's fish farming sector, giving it the potential to bank on favourable climate conditions and untapped land and water resources.
Researchers in China caution that some commercial probiotics for the aquaculture industry may be mislabelled, and also contain cytotoxins and antibiotic resistance genes that can be passed to other organisms.
Though insect protein startups are generating splashy headlines and bringing new players into the aquafeed industry, single-cell and microbial proteins might be a key feed component in the future.
A recent feed trial has found that supplementing Nile tilapia diets with bakers’ yeast (Saccharomyces cerevisiae) can change the fishes’ intestinal morphology, leading to improved nutrient uptake, immune responses and growth performance.
While insect production is likely to grow significantly in the coming years, it will be vital for the aquafeed industry to make the most out of what is likely to remain a fairly niche ingredient and not treat it as a simple substitute for fishmeal or soy.
Petter M Johannessen, director general of the IFFO, believes that marine ingredients play a crucial role in developing aquafeeds with a low carbon footprint.
Hatch and Conservation International (CI) have put 10 female-led aquaculture businesses through their paces as part of their first-ever Women in Aquaculture Innovation Studio programme.
As the aquaculture industry expands, it needs every feed option – both conventional and alternative – at its disposal. But what steps can the sector take to bring sustainable feed ingredients online?
Indonesia’s aquafeed producers – be they industrial players or farmers who produce feed independently – are increasingly looking towards the use of local and sustainable alternatives to fish meal and soy.
