Some of the leading figures in Artemia research are planning to join forces and launch an International Artemia Aquaculture Consortium (IAAC) later this year.

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.

Adding microalgae T pseudonana (Thalassiosira pseudonana) to culture water can improve overall water quality, suppress vibrio levels and boost growth rates for intensively farmed whiteleg shrimp.

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.

Why optimal ionic composition and ratios in low salinity water and diet formulation is vital for the normal physiological functions of Penaeid shrimp.

Ahead of the inaugural meeting of the World Aquaculture Society’s African Chapter, which is due to take place in Alexandria this month, Harrison Charo Karisa – one of the key organisers of the event – discusses the prospects of the continent’s aquaculture sect…

Oladejo Olanrewaju Olumide is the chairman of Ikorodu Fish Farm Estate and second vice-president of the Lagos State Catfish and Allied Farmers Association (LASCAFAN) – the umbrella body of all catfish farmers in Lagos State.

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.

Novel means of improving shrimp health – including the use of alternative feed ingredients – are due to be the subject of a short, free webinar taking place on 10 November. Organised by The Fish Site and Calysta, the event has been inspired by trials …

Shrimp fed diets containing FeedKind, a novel microbial protein produced by Calysta, have been shown to be more resistant to Vibrio parahaemolyticus – the source of early mortality syndrome (EMS).

Catfishes have surpassed tilapia in global aquaculture production and – helped in part by the sheer number of their species and their extensive geographical range – they are set to remain at the top table.
