Breeding & genetics

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…

Oceanpick, which is on track to produce 1,200 tonnes of barramundi this year and is one of Sri Lanka’s flagship aquaculture producers, has ambitions to reach 3,000 tonnes a year.

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.

Ecuador’s relatively extensive shrimp farming techniques have ensured that their shrimp are robust enough to cope with the presence of pathogens that would be disastrous in most parts of Asia – allowing them to continuously produce shrimp sustainably for decad…

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 – …

Advances in black tiger prawn (Penaeus monodon) genetics are leading to an impressive renaissance of the species in multiple regions, according to Robins McIntosh.

Although the $4 billion giant river prawn (Macrobrachium ronsebergii) sector has largely stagnated over the last decade, new breeding programmes could help pave the way for its resurgence.

Recent genetic advances are being heralded as possible game-changers for the tiger prawn (Penaeus monodon) farming sector, potentially bringing a welcome renaissance to a sector that has fallen far behind vannamei shrimp in the past decades.
