Marine permaculture, the macroalgae aquaculture system developed by The Climate Foundation, seeks to harness wave energy to restore natural nutrient upwelling and grow seaweed at scale. If initial trials continue to be successful, it could be a feasible way to…

Georg Baunach, co-founder of Hatch*, explains the ethos behind the company’s newly launched Blue Revolution Fund (BRF) as it begins to work with startups and SMEs to increase ocean biodiversity, tackle climate change and create positive social outcomes for coa…

Recent trials from the F3 Innovation Network found that it is feasible and economically viable for aquaculture nutritionists to significantly reduce – or even eliminate – fish meal and fish oil from the diets of carnivorous fish species like largemouth bass, a…

Norway’s Atlantic salmon sector published their feed composition and utilisation data from 2020, showing more novel ingredients in their formulations and greater salmon output – but as inflation and global commodity prices surge, feed companies may face diffic…

Though indoor shrimp farming has been tapped as a potential disruptor in the aquaculture space, investors have been hesitant to sign on the dotted line. But according to Aurore Gil of ADM Capital Europe, this reflects an investment stance that’s better charact…

Though many are still at the pilot stage and haven’t been proven at an industrial scale, analysis from Spheric Research suggests that indoor shrimp farming has huge potential to transform the wider industry.

Aine O'Donnell and Aine-Lisa Shannon are bringing aquaculture to Ireland's primary schools as part of the Bord Iascaigh Mhara (BIM) Aquaculture Remote Classroom (ARC), a mobile classroom that showcases aquaculture's role in coastal communities and climate-posi…

Heather Sadusky has been on a mission to give consumers access to sustainable seafood and has worked across the US, Hong Kong and the Caribbean to achieve her goals. She's now leading the Sustainable Fisheries Partnership's traceability efforts in the aquacult…

In three years Ireland's Pure Ocean Algae has domesticated a wild dulse, a red seaweed species, and created a fully-fledged macroalgae value chain. The Fish Site sat down with founder Michael O'Neill to learn more about his processes and Ireland's pot…

A new multi-cohort trial has demonstrated the efficacy of semi-closed containment systems (SCCS) for Atlantic salmon – with results showing lower lice counts, higher growth rates, higher final weights and higher survival rates for salmon in Preline’s SCCS comp…

A new analysis finds that the industry still needs to lay critical groundwork before offshore salmon aquaculture is seaworthy.

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.

Taprobane Seafood’s Tim O’Reilly faced a four-year approval process and significant protests when introducing Litopenaeus vannamei to Sri Lanka – but has since found that his eco-certified shrimp are an economic bright spot and a key element in Sri La…

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 – …

After studying architecture and design in university, Cynthia Darmawan decided to join Delta Marine, her family's shrimp trading business. Since then, she's helped the business expand and plays a leading role in Indonesia's fast-growing shrimp sector.

Stronger and larger aquaculture units and enclosed set ups could be the next stage of aquatech, according to a review of Norway’s development license scheme for Atlantic salmon.

Seaweed aquaculture and kelp forest restoration are getting a tentative nod as a blue carbon strategy – but the way policymakers structure carbon credits and offsets may make its benefits theoretical instead of bankable.

As land-based and RAS facilities proliferate, they need a way to address their waste footprint. “Circular aquaculture” could be the way forward – but should producers rely on bacteria, algae or biogas to achieve circularity?

Dr Melony Sellars, CEO and managing director of Genics Pty Ltd, recently developed four new real-time PCR assays that can help detect the presence of decapod iridescent virus (DIV1) in shrimp.

Researchers are beginning to highlight the potential of immunostimulants as a sustainable disease prevention strategy for shrimp aquaculture. Here’s a run-down of how these molecules work, their origins and how they can be used to combat outbreaks of white spo…

Aquaculture’s technology spotlight tends to focus on offshore cages, satellites, AI sensors and recirculating aquaculture systems (RAS) for major finfish species – but this narrative overlooks aquatech’s ability to revolutionise small-scale production and safe…

The ocean has enormous – and largely untapped – potential to cycle and sequester excess atmospheric carbon through processes like seaweed cultivation. So how can stakeholders tap into this potential to scale CO₂ removal efforts and deliver climate wins?

Suzan Shahrestani, CEO of Baltimore-based growth company Minnowtech, wants to use sonar to help shrimp farmers optimise their process – and has developed a tool that will let shrimp farmers leverage their biomass data to become more sustainable and efficient.

A recent trial demonstrated that growing blue mussels (Mytilus edulis) alongside sugar kelp (Saccharina latissima) can significantly increase seaweed yields and enhance pigment content in the blades – but the benefit could come from improved …

Replacing fish oil with linseed oil – a popular dietary supplement for humans – is emerging as a workable nutrition strategy for artic char, brook charr and their reciprocal hybrids.

Investors looking to support sustainable marine aquaculture and the blue economy need accurate ocean data to make evidence-based decisions and de-risk their financial offerings – but a lack of reliable data might be curtailing their efforts.

Emerging research has shown that nutraceuticals in aquafeed can delay the onset and progress of clinical signs of amoebic gill disease (AGD) in farmed Atlantic salmon.

OpsSmart's Sharmeen Khan is keen to bring blockchain traceability to the aquaculture sector – giving seafood producers and consumers a tech solution that allows end-to-end visibility and transparency.

A side-by-side comparison of conventional and insect-based aquafeed ingredients has found that insect meals and oils come with a larger carbon footprint and require more energy to produce than marine ingredients – but this discrepancy might be short-lived.

Though seaweed operations are diverse – specialising in various species and operating in different economic circumstances – today’s macroalgae practitioners need to stay grounded in science as they work towards their scale and sustainability goals for 2030.

Results from an integrated multi-trophic aquaculture (IMTA) project with sea cucumbers and marine finfish show that the system is feasible, but practitioners need to refine their designs to ensure the sea cucumbers thrive.

Despite only representing about 1 percent of global seaweed cultivation volumes, green macroalgae (Chlorophyta) could play a decisive role in the commercial seaweed sector as it expands and diversifies.

By adopting the “basic building block” of tilapia farming, producers across Africa can establish and scale operations in both urban and rural environments – moving Africa’s tilapia industry beyond subsistence farming.

New analysis suggests that pond aquaculture could be the tilapia industry’s best way to profitably intensify production – and that, other than for a few notable exceptions, recirculating aquaculture systems (RAS) will remain relatively unprofitable in the near…
