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.
GLOUCESTER, MA – In a move to catalyze early-season commercial activity, NOAA Fisheries has officially transferred Atlantic bluefin tuna quota from the year-end December period to the January–March 2026 window.
The temporary rule, effective January 8, 2026, reallocates tonnage within the General category, significantly increasing the first-quarter subquota to 63.7 metric tons while reducing the December allocation to 11.0 metric tons.
Key Impacts for Vessels
The adjustment applies to General category permitted vessels and HMS Charter/Headboat vessels with commercial sale endorsements. By front-loading the quota, NOAA aims to provide immediate opportunities for operators during the traditionally slower post-holiday market.
Market Timing: Increased landing limits allow for better dealer coordination and auction planning during Q1.
Regulatory Context: This is an interim measure while NOAA aligns 2026 baseline quotas with recent ICCAT international conservation decisions.
Immediate Next Steps for Operators
Fishermen should verify that all permits and endorsements are current before targeting bluefin. Because this is a temporary shift, operators are encouraged to coordinate closely with dealers and monitor landing records to ensure the fleet stays within the revised 63.7 mt limit.
Keep an eye on upcoming 2026 rulemaking, as further baseline adjustments are expected later this year.
With a 37-year history in the Magallanes Region, Pesca Cisne has consolidated its leadership in the Chilean Seabass (Patagonian Toothfish) industry with the addition of the "Isla Edén."
This world-class longliner represents an investment exceeding $8 million and will be officially inaugurated this Friday, January 15, at the Arturo Prat pier in Punta Arenas.
Cutting-Edge Technology for the Drake Passage
The "Isla Edén" is more than just a vessel; it is a sophisticated processing plant designed in Norway to withstand the extreme conditions of the far south. Key specifications include:
Impact on the Magallanes Economy
The arrival of this ship strengthens a network that currently supports 100 direct jobs and over 1,500 indirect positions in the region. "This investment not only modernizes our fleet but also injects dynamism into the local economy and improves the quality of life for our workers," the company stated.
With the "Isla Edén," Pesca Cisne reaffirms its commitment to the development of Magallanes, focusing on high-quality extraction and environmental responsibility.
Ecuadorian Skipjack Remains More Expensive Than Bangkok As Fishing Resumes on January 19
The price gap for skipjack (Katsuwonus pelamis) is once again a barometer of tension in the global tuna market. Fish landed in Manta, Ecuador, maintains a significant premium compared to deliveries destined for Bangkok, Thailand. This difference, far from diminishing, continues to put pressure on the margins of the Ecuadorian canning industry just before the purse seine fleet resumes operations in the IATTC area following the seasonal closure.
The Nueva Pescanova Group has begun the validation phase of the first prototypes of a new artificial intelligence (AI) tool to optimize surimi production. Implementation will begin at the Chapela factory this January. This solution is part of the "PremIA" R&D project, which aims to develop a new AI-based predictive system to improve efficiency and quality in the production of fish, shellfish, and related products.
The goal of PremIA is to design and implement a tool that analyzes large volumes of information, detects hidden patterns, and generates statistical models to forecast future production performance.

Chinese abalone firm Fujian Xiangbin recently acquired Best Aquaculture Practices (BAP)two-star certification in an effort to expand sales in the domestic premium market and also grow international sales of its products.
Securing BAP two-star status in late 2025 marked a “milestone breakthrough” for the company, according to Xiangbin CEO Xiuying Chen.
Located in the Southeastern Chinese province of Fujian where much of China’s abalone production is centered, Xiangbin started out in live abalone trading in 2003 before expanding into farming, processing, distribution, and global sales

The Fisheries Research and Education Agency (FRA) released its latest resource assessment for the Japanese common flying squid (Todarodes pacificus) on December 26, 2025.
While coastal regions like Sanriku saw a surprising uptick in migrations last year, experts warn that the species remains in a critical state overall.

The "Pacific Shift" Explained
According to the National Research Institute for Fisheries Science, the 2025 surge along the Pacific coast was driven by two specific environmental factors:
Slightly Higher Spawning Success: A marginal increase in winter-born parent fish compared to the previous year provided a larger initial larval base.
Ocean Current Diversion: Favorable current patterns acted as a "conveyor belt," pushing newborn larvae toward the Pacific side rather than their traditional routes into the Sea of Japan.
A Tale of Two Stocks
Despite the localized bounty in the Pacific, the broader picture is bleak. The autumn-born stock, which primarily supports the Sea of Japan fisheries, continues to hover at all-time record lows.
Japanese fisheries experts emphasize that "resource recovery" is not yet on the horizon. The low density of parent fish in the autumn-born group suggests that the reproductive cycle remains fragile. Marine biologists point to rising sea temperatures in the East China Sea spawning grounds as a persistent threat
Anfaco-Cytma Reveals Rabat Will Close Exports to Supply Its Industry and Sell in the EU
Zakia Driouich, Morocco's Secretary of State for Maritime Fisheries, announced on January 7 that her country intends to temporarily suspend frozen sardine exports starting February 1, according to the Vigo-based employers' association Anfaco-Cytma. If implemented, this "could have a significant impact on the activity and employment" of Spanish and EU canneries and processing industries.
