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.
Showcasing Sustainable Seafood: Protecting Health and Ocean Resources for Generations to Come
Maruha Nichiro Corporation (Headquarters: Koto-ku, Tokyo; President and CEO: Ikemi Masaru) will participate in the "Living with Food" event, a platform for exploring the future of food in Japan. Organized by Mitsui Fudosan Co., Ltd. and Discover Japan Co., Ltd., the event will take place over ten days, from January 10th (Friday) to 19th (Sunday), 2025, at Tokyo Midtown Hibiya (Chiyoda-ku, Tokyo).
As part of its medium-term management plan, “MNV 2024: Creating the Future of the Ocean and Life,” Maruha Nichiro has identified "creating health value and providing food that supports sustainability" as a key priority. At the event, the company will highlight two significant initiatives:
Promoting Health through Canned Blue Fish Products:
Maruha Nichiro will showcase the benefits of its canned blue fish products, emphasizing their potential to address contemporary health challenges. These nutrient-rich offerings are designed to support well-being while appealing to modern dietary needs.
Advancing Sustainable Seafood Practices:
The company will also present its efforts in promoting certified sustainable seafood—products that prioritize both environmental and social responsibility. These initiatives align with global sustainability goals, ensuring the long-term health of ocean ecosystems while meeting consumer demand.
The Ministry of Production (PRODUCE) reported that Manufacturing GDP grew 6.7% in November 2024, accumulating five months of uninterrupted progress; it would have also contributed S/6,730 million (at constant prices) and contributing 13.3% to the national GDP.
“The growth recorded by the Manufacturing sector in November 2024 is mainly due to the notable increase in the primary industry (fishery products and metal refining). Likewise, it was favored by the growth of the non-primary industry (consumer goods, capital goods and industrial services),” said the head of PRODUCE, Sergio González.
In this way, in the cumulative period from January to November 2024, manufacturing industrial production grew by 3.2% compared to the same period in 2023.
This result would be associated with the greater activity of industrial fishing in the second quarter; favored by oceanographic conditions. Also, the recovery of domestic demand around 3.5% and industrial exports (+10.9%) had an impact.
It should be noted that, regarding the contribution of primary manufacturing, in November 2024 it experienced a notable increase of (+18.1%), driven mainly by the greater production of the fishery products industry (+32.1%) attributable to greater availability of raw materials.
It has been discovered that the Far East Crab Catchers Association (CCA, Vladivostok), which is made up of crab producers in the Russian Far East, has suspended its certification from the Marine Stewardship Council (MSC).
The suspension has been made for all three types of crab that are subject to certification: red king crab, blue crab, and snow crab (Opilio species). As the association was the only one in the Far East to have been certified for the Opilio species, from now on, no certification for Opilio species from the Far East will be available.
The association obtained certification for the three species on October 12, 2023. The suspension comes after MSC announced in 2024 that it would suspend certification for the three species.
Launched in October, France Terre de Pêches brings together seven producer organizations: OP du Sud, Les Pêcheurs de Bretagne, Orthongel, From Sud-Ouest, From Nord, Sathoan and OP de La Cotinière, which represent 1,000 fishing companies and 5,500 fishermen, reports Vincent Schumeng from Produit de la Mer.
The aim is to promote French fishing in all its aspects. "The French don't know much about fishing," says the coalition's spokesperson, Perrine Cuvilliers - who is also the general secretary of OP du Sud. "We want to show that our fishing is beautiful and diverse, and to break down preconceived ideas."
The coalition's messages, particularly via its online media, will focus on good practices for fishermen but also on the challenges facing the profession: modernizing the fleet, recruiting young fishermen, etc. "We want to dust off the image of the fisherman and show the importance of this sector in food sovereignty,"concludes Perrine Cuvilliers.
Defending fishing means ensuring that there will be French fish on the shelves. Note that this coalition of POs has no legal status, so funding is collective.
Since 2023, when Mowi joined forces with El Corte Inglés with the aim of continuing to strengthen its presence in the Spanish market by investing in innovative shopping experiences as an easy and quick solution to introduce top-quality salmon into the diet, the Norwegian company has carried out various initiatives to promote its products among consumers.
The latest of these initiatives comes from new unconventional sales points at El Corte Inglés in Sotogrande in Cádiz and at El Capricho in Marbella “so that their customers can enjoy a unique shopping experience, which highlights the company's track record, its firm commitment to sustainability and its integrated value chain, which seeks the highest quality, flavour and freshness of the products”

The European Commission has set new, more stringent requirements for avoiding listeria contamination in ready-to-eat (RTE) foods.
The updated rules only apply to RTE foods, which have been the cause of many recent listeria cases in the E.U. and are, thus, considered a high-risk food group.
The new rules establish a lower contamination threshold and a longer time frame in which producers are responsible for food safety than those that came before.

Aquabounty’s land-based salmon farming equipment heads to auction.
The remnants of failed land-based salmon farming pioneer AquaBounty are set to go under the hammer in February 2025.
The auction features a range of high-value, unused aquaculture equipment, offering a rare opportunity for industry players to acquire state-of-the-art technology at reduced costs.
AquaBounty, once a high-profile advocate for land-based salmon farming, struggled to overcome the economic and operational challenges of its ambitious expansion.

Despite challenges, including increased competition from other countries, trade wars and market barriers, Vietnam’s seafood exports are expected to continue to increase and could reach a total value of US$ 11 billion this year – a feat last achieved in 2022, according to the Vietnam Association of Seafood Exporters and Producers (Vasep).
In 2024, the country’s seafood exporters overcame many difficulties and challenges in terms of raw material sources, reduced demand, increased competition, and increased market barriers. Nevertheless, an export value of over $10 billion was achieved, not including more than $250 million from its overseas fishmeal sales.
According to data from the Federal Fisheries Monitoring System under the Federal Agency for Fisheries, Russian fishermen have recorded a significant increase in catch volume in early 2025.
Since the start of the year, total catches by Russian users have reached 58.6 thousand tons of aquatic bioresources, an increase of 5.8 thousand tons compared to the same period in 2024.
Regional Catch Overview:
Far Eastern Basin: 54.1 thousand tons (up by 6.3 thousand tons from 2024).
Northern Basin: 2.6 thousand tons (unchanged).
Western Basin: 0.2 thousand tons (unchanged).
Azov-Black Sea Basin: 0.3 thousand tons (up by 0.1 thousand tons from 2024).
Volga-Caspian Basin: 0.7 thousand tons (up by 0.6 thousand tons from 2024).
In addition, the Russian fleet has harvested approximately 0.68 thousand tons in exclusive economic zones of foreign states, conventional areas, and the open part of the World Ocean.
Fresh catches are being prioritized for the domestic market to meet local demand.
