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.
The Far Eastern fishing fleet has been boosted with the addition of the new crab fishing vessel, the Alexander Sapozhnikov.
Built by the Onega Shipyard for the Russian Crab Group under the investment quota program, the national flag was recently raised on the vessel, marking its official commissioning.
The ship is designed for sustainable crabbing and live catch transport. It features a specialized two-level hold with modern monitoring systems (temperature, salinity, oxygen) to ensure a high preservation rate of 98% for the catch.
Ilya Shestakov, head of the Federal Agency for Fisheries, emphasized the significance of the new vessel: "Each new vessel is a step toward achieving our strategic goal—the modernization of the domestic fishing fleet... Furthermore, automation and digital process control are ensured for more efficient operations at sea."
The vessel is named in honor of Alexander Anatolyevich Sapozhnikov, who led the Russian Crab Group from 2020 to 2024 and significantly contributed to the company's fleet and staff expansion. (Source: Federal Agency for Fisheries)
The Russian State Duma is considering a draft law to authorize the canning of cod liver oil directly on fishing vessels.
This measure seeks to solve the problem of wasting large quantities of this valuable byproduct, which is often discarded due to its short shelf life and the inability to process it onboard.
The proposal amends the Law on Fisheries to allow vessels equipped with specialized gear to produce canned cod liver during the fishing process.
Objective: To increase the supply of cod liver to the domestic market, valued for its high content of beneficial fatty acids.
Economic Benefits: It is expected to reduce resource depletion, increase efficiency, add value, create jobs, and improve fishermen's incomes.
Implementation: If approved, the regulation will take effect on September 1, 2026. A transition period until 2030 is proposed to allow companies to establish processing plants in the northern region.
Legislators view this initiative as a key step for the development of the Russian fishing sector, especially in the context of declining cod stocks.
Russian scientists at Kuban State Agrarian University (KubSAU) are developing the country's first oral vaccine for farmed fish to combat the deadly disease aeromonosis.

Aeromonosis is a dangerous infection that causes mass mortality in aquaculture. Traditionally treated with antibiotics, the disease has led to the emergence of resistant bacterial strains, making the development of new solutions critical.
The new drug is designed to combine an antigen and an adjuvant into a single molecule. Scientists say this innovative design will allow fish to develop immunity without injections, significantly reducing the need for antibiotics in aquaculture.
KubSAU estimates that the vaccine will help reduce fish mortality and promote herd immunity, ultimately cutting fish farming costs by approximately 19%. Researchers are currently isolating the responsible bacterial strain in the lab, with state registration of the vaccine planned for early 2029.
Norway & the UK fish & chips industry: A strategic partnership between two cornerstone industries.
Fish & Chips is far more than a beloved British meal—it stands as a symbol of national identity and cultural heritage. From its humble beginnings in the 19th century, this dish became a staple for the working class, offering affordable nourishment through times of hardship and war.
Today, Fish & Chips remains a thriving industry, deeply connected to the quality and sustainability of Norwegian cod, and strengthened by close collaboration between British and Norwegian partners.

ARVI regrets that the pact has "focused exclusively on the environmental aspect," setting catches at the lowest possible limit of the range. The entity criticizes that the social and economic aspects of the Common Fisheries Policy (CFP)—which should carry equal weight—have been ignored.
This decision adds to a "constant reduction" in fishing opportunities in recent years for key species of their Gran Sol (Faroes/West of Scotland) fleet, such as Hake and Megrim, seriously affecting the sector's viability.
With more than 60 actions aimed at strengthening the competitiveness of the fish and seafood canning and processing industry
Anfaco-Cytma has taken stock of 2025, which it describes as "demanding," in which it carried out more than 60 actions aimed at strengthening the competitiveness of the fish and seafood canning and processing industry. This intensive work, they explain, "covered strategic areas such as food safety and quality, sustainability, international trade, labor relations, and innovation, through continuous public-private collaboration."
In the words of Roberto Alonso, Secretary General of Anfaco-Cytma, “2025 has been a year in which the regulatory and technical burden, along with international geopolitical events, has demanded anticipation, rigor, and ongoing dialogue with government agencies regarding their specific competencies.

Industry fury as police probe alleged misuse of major salmon brands.
Norwegian police have opened a formal investigation into alleged illegal export practices at Bergen-based salmon trader North Tandem, following NRK disclosures and multiple complaints from industry companies and the Food Safety Authority. Several individuals in the company are charged with document forgery, breaches of the food law and providing false information to the Food Safety Authority. The charges also cover violations of regulations governing the export of downgraded production fish.

Andfjord Salmon has brought in a new lead contractor to complete the work at its Kvalnes site in the Norwegian Arctic.
The company dismissed the current contractor AF Hæhre & Contur in an ongoing row which has led to 76 workers being warned they could lose their jobs.
Andfjord said in an Oslo Stock Exchange announcement last night that it has now engaged the company Harald Nilsen together with the concrete specialist Nornebygg.

The last time the price was higher was in week 16, which was Easter week.
Last week’s price was also NOK 5.38/kg better than the same week last year.
The average spot price so far this year is NOK 76.25/kg, compared to NOK 92.57 a year ago.

India and Russia are working to form closer seafood ties after the leaders of the two countries met at a business forum in New Delhi, India.
Russian President Vladimir Putin and Indian Prime Minister Narendra Modi met during the 23rd Russia-India Business Forum in early December, with both leaders reaffirming support for each other and the strengthening of the Special and Privileged Strategic Partnership between the two countries. The partnership, established in October 2000, promises cooperation in a number of areas including security, economic ties, nuclear energy, defense, and natural resources like seafood. As part of those closer ties, the two leaders said India and Russia are setting a trade target of USD 100 billion (EUR 85 billion) to be achieved by 2030.
