Species development

Most of the fish currently farmed in the sea are carnivores, but there’s a strong argument for producing more marine herbivores, which don’t depend on diets containing fish meal and fish oil.

Indonesia has developed a range of local strains of tilapia, largely to improve growth rates and general disease resistance, but there’s still scope for these to be more widely adopted.

Cryopreservation – involving the freezing and ultra-low temperature storage of ova and sperm – has been demonstrated with varying degrees of success across a range of farmed aquatic species, but more standardised techniques are needed to ensure that it works c…

Flexible ingredient formulations, enzymes, optimised microbiomes and genetics are playing their part in bringing multiple farmed fish species closer to precision nutrition, according to Alltech’s global manager of aquaculture research.

Colombia’s aquaculture industry has been stuck in a cycle of low productivity and low profitability, but a recent value chain analysis notes that the country could capitalise on its climate and geography to become a leading producer of tropical – and native – …

When I was contemplating a topic for this month’s article, I was reminded of a question my daughter asked me several years ago: “Can we feed our dogs a vegetarian diet?”

Nueva Pescanova’s plans for starting the world’s first commercial octopus farm may have caused an uproar in some quarters of the mainstream media, but aquaculture of the animals could be the best hope for sustaining wild stocks.

Saudi Arabia’s Tabuk Fisheries Company recently hatched its first batch of native sobaity bream larvae – a breakthrough that could pave the way to diversifying the Middle East’s burgeoning aquaculture sector.

Although native to the Atlantic and Gulf Coasts of North America, red drum are now farmed across a wide geographical range – with some producers proving more enduringly successful than others.

Perhaps one of the least aquatic forms of aquaculture involves the farming of crocodiles, alligators and caimans. These animals are referred to as semi-aquatic, and their husbandry is in some ways more similar to livestock production than to fish or shellfish …

Researchers in Ghana believe that there’s now scope to fulfil the potential of the African bony tongue – commonly referred to as “super cu” in Ghana – as a key aquaculture species.

Petros Thomas, who’s Greek and been in the marine aquaculture sector for 32 years, is currently working as assistant general manager and production operation manager for the Tabuk Fisheries Company in Saudi Arabia.

The aquaculture industry could be progressing towards commercial tripletail production after wild-caught specimens were able to spawn and larvae grew to maturity in a recirculating aquaculture system (RAS).
