IN BRIEF - Shrimp and Oysters in the Same Tank – Benefits of Multitrophic Aquaculture
UNITED STATES
Friday, August 02, 2024
Scientists are developing technologies that would make it possible to grow two valuable commodity items even in an ordinary basement.
A scientist from the College of Life Sciences and Agriculture (COLSA) at the University of New Hampshire (UNH) is studying the benefits of integrated multi-trophic aquaculture (IMTA).
IMTA is a system in which two or more organisms are grown together. This process could make shrimp farming more sustainable and support the growth of the industry in the United States.

Elizabeth Martin, a graduate student in the marine biology program at COLSA, is studying IMTA systems that pair farmed shrimp with filter-feeding species such as oysters to determine whether the pairing will reduce the amount of ammonia and phosphorus that remains in the water during the shrimp farming process.
"Most of the shrimp we consume comes from overseas, and oysters are also one of the most valuable imported seafood products, so developing a local industry will help reduce dependence on these overseas markets," says Martin.
Although shrimp produce ammonia naturally, there are other sources of ammonia, including shrimp feed, which often contains high levels of nitrogen, natural breakdown of feed in the water, dead organisms, feces, and other materials that complicate shrimp aquaculture production. However, in the natural environment of shrimp, there are filter feeders, such as clams, that remove excess nutrients from the water.
US firm wants seat at the table as it expands from Chile into Norway and Scotland
The Global Salmon Initiative (GSI) has announced that Sudvet Corp., an animal welfare company headquartered in Los Angeles, California, and specialising in botanical and biotechnological solutions for aquaculture, has joined as an associate member.
Sudvet develops botanical solutions aimed at reducing antibiotics and antiparasitic use in salmon farming. It offers a number of products that include AQ Bliss, a feed additive formulated with essential oils that is said to prevent fish stress during handling and help maintain the quality of the fish’s mucus.

Direct grants will offset higher fuel and fertiliser costs caused by the Middle East crisis
The European Commission approved Portugal’s €30 million scheme for agriculture, fisheries and aquaculture. Companies may receive up to €50,000, including €0.10/litre for agricultural or marine diesel consumed from April 1-June 30, 2026.
The plan aims to cut regulatory burdens while strengthening science-based fisheries management.
NOAA Fisheries unveiled priorities to expand domestic seafood production after input from more than 700 stakeholders. Reforms target sustainable fishing opportunities, stronger markets and infrastructure, processing capacity and tougher action against IUU fishing.
IFOP completes the 2025–2026 phase of a key program supporting wild seed collection and production planning
Chile's IFOP, with funding from the Undersecretariat for Fisheries and Aquaculture, completed the 13th stage (2025–2026) of its mussel larval monitoring program. The initiative tracks larval abundance, spawning, wild seed availability and oceanographic conditions, helping producers identify optimal collection periods, reduce uncertainty and strengthen the sustainability of southern Chile's mussel farming industry. The closing event gathered 129 participants from industry, government, academia and research centers.
Fiskistofa will deploy unmanned aircraft throughout September 2026 to monitor fishing operations and discards.
Drone footage will be closely reviewed to identify fish discarded at sea. Fiskistofa reminds fleets that permitted releases must involve viable fish, while species and estimated kilograms discarded must be electronically recorded in fishing logbooks.
Novosibirsk State University scientists are developing a high-protein feed additive from Yarrowia lipolytica, with no current Russian equivalent.
The yeast biomass provides essential amino acids, B vitamins, lipids, phospholipids and nucleotides that may stimulate fish and poultry growth. Its beta-glucans and mannan-oligosaccharides can strengthen immunity and reduce antibiotic use.
Trident Aqua Services has celebrated the naming of Grip Discovery in Puerto Montt, Chile, together with customer Multi X. Delivered from Sefine Shipyard and designed by Salt Ship Design AS, the vessel is the largest and most advanced wellboat currently operating in Chile, with a well capacity of 4,000 m³.Built to support a wide range of aquaculture operations, Grip Discovery combines advanced fish handling systems, high biosecurity standards and substantial freshwater treatment capacity. The vessel introduces a new generation of wellboat technology to the Chilean salmon industry, bringing together large-scale freshwater production, battery-hybrid propulsion and highly efficient treatment systems in a single platform.
Suspected and confirmed Infectious salmon anaemia (ISA) has been reported at three locations in the Bodø region of northern Norway over the past week.
The incidents are being seen as one of the most serious episodes in a single area for some time.
The first report, which came on August 24th is at a location in Saltdalsfjorden where both Edelfarm AS and Salten Stamfisk AS have fish at the site, which is operated by Edelfarm AS. Confirmation or otherwise is awaited.
The next incident, which has now been confirmed, happened at sea location 32397 "Storvika" in Skjerstadfjorden in Bodø.

Norwegian salmon exports reached a monthly record in August, with 153,602 tonnes shipped at a value of NOK 12.3 billion (€1.14 billion).
Volumes rose 7% year on year while export value increased 19%, or NOK 2 billion (€186 million). The total was NOK 19 million (€1.8 million) above the previous monthly record set in October 2025.
The rise helped push Norway's total seafood exports to a record NOK 16 billion (€1.49 billion) for the month, up 14% year on year.

The two-day conference will highlight technologies, investment and business models that turn seafood side streams into high-value products.
100% Fish for Profit, on 23–24 September in Iceland, will unite industry, researchers and investors to explore full fish utilisation, from AI and advanced processing to nutraceuticals, pharmaceuticals, cosmetics and biomaterials.
The panel will explore how collaboration across industry, research, policy and investment can accelerate innovation and scale full-utilisation solutions internationally.
