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.
Spain extends fleet compensation until September 30 and increases funding to €35 million
Spanish fishing vessel owners have already received—or are about to receive—the first round of aid to offset the fuel price hikes caused by the war in the Middle East. On June 18, the Ministry of Agriculture, Fisheries and Food published the list of 4,308 vessel owners and 4,650 vessels set to receive an initial payout of €6.8 million. This is part of the €25 million package authorized by the European Commission to help Spain mitigate the additional costs resulting from the conflict. As of today, June 30, the subsidy covers 20 cents per liter—calculated as a flat rate based on average rather than actual consumption—subject to a cap of €200,000 per vessel and €400,000 per owning company.

Ibercisa Deck Machinery plays an active role as an equipment supplier in the renewal of the fishing fleet operating in the South Atlantic. The Vigo-based company designs, manufactures, and supplies solutions that integrate marine machinery with onboard energy recovery systems. The integrated design of the entire equipment suite enables greater catch efficiency and superior equipment control.
When designing equipment for fishing vessels in this fishing ground, the harsh conditions and the intense operational demands of the fisheries are taken into account. Furthermore, having a precise control system for the main and auxiliary winches is crucial to maximizing product quality—both during trawling and throughout deck handling, from the stern ramp to the hold.

Belize partners with Satlink to strengthen global fisheries traceability through electronic monitoring
The Belize High Seas Fisheries Unit (BHSFU) has taken a strategic step toward strengthening fisheries oversight and marine conservation by selecting technology company Satlink as the official Electronic Monitoring (EM) provider for its high-seas fleet. This partnership is part of Belize’s broader plan to deploy an Electronic Monitoring Program (EMP) across its distant-water industrial fishing fleet by 2027, enhancing the country’s monitoring, control, and surveillance (MCS) capabilities while improving traceability and alignment with international fisheries standards.
Chinese state-run newspaper Global Times has highlighted Erling Haaland’s role in promoting Norwegian salmon, reporting that the footballer’s advertising campaign has become a social media talking point among Chinese consumers.

The South Korean government has announced new supply expansion measures to stabilise prices of key seafood items, including mackerel, hairtail and squid, as part of its broader plan to ease the burden of living costs in the second half of the year.
As part of the latest inflation control measures, the government plans to inject a total of KRW 1 trillion in fiscal support to stabilise consumer prices. For seafood, the government said it will directly import 2,000 tons of Norwegian mackerel and redirect part of domestic export-bound mackerel supply to the local market, offering it at around half price.

Norway’s fish farming industry is set to be one of the beneficiaries of a major ship tunnel project, for which a key contract has now been awarded.
The Oslo-based civil engineering giant AF Gruppen has been awarded a billion kroner (£80m) contract to build the Stad Ship Tunnel, one of Norway’s biggest transport projects.
The Stad Ship Tunnel is a planned 1.7-kilometre (just over one mile) underground passage in Norway designed to allow ships to bypass the highly unpredictable and dangerous Stadhavet Sea, an area in the west of the country which marks the dividing point between the North Sea and the Norwegian Sea.
