Retail chain Aldi Süd has announced a global policy to end eyestalk ablation in its shrimp supply chain by 2030 and implement electrical stunning for all of the farmed shrimp it sources by 2035.

With this move, all 11 of the U.K.’s major supermarkets have now set time-bound commitments on shrimp welfare.

Amid growing regulatory and public scrutiny, Aldi Süd’s shrimp pledge completes a shift that began with Sainsbury’s, M&S, and Tesco in 2024, followed by such retailers as Waitrose, Iceland Foods, Co-op, and Morrisons in 2025, and then Asda and Lidl GB earlier this year.

Melanosis, one of the main alterations affecting the quality of salmon fillets, could originate from internal biological processes rather than damage associated with handling, according to a recent study by Norwegian scientists.

Among the factors that could influence this change in the salmon muscle, the following have been described: diet, infectious agents, vaccination, traumatic injuries, mechanical stress during handling, environmental factors, genetics, among others.

Following a year-long scoping process with stakeholders across the seafood sector, the Ethical Tuna Collaboration (ETC) has launched its design phase, marking a major step toward addressing forced labour risks in tuna supply chains serving the U.S. market. The project is the latest from responsible seafood movement convenor, Conservation Alliance for Seafood Solutions (CASS).

The ETC brings together a multistakeholder working group to design the initiative. This differs from traditional initiatives, which are typically led solely by industry or civil society, in that it fosters shared responsibility and coordinated action across the system.

Venezuela’s aquaculture sector is facing a sharp downturn. The president of the Venezuelan Aquaculture Society, Eduardo Castillo Bracho (pictured), reported this Tuesday that white shrimp production dropped by ???? 48% over the past year, due to “exogenous factors.”

“We are coming from a difficult year,” he said. According to unofficial reports, exports fell from 60,000 tons to between 32,000 and 34,000 tons, highlighting the scale of the decline.

In an interview on the program “Dos más Dos” on Unión Radio, Castillo also proposed the creation of an exclusive aquaculture law to help revive the sector. In his view, current legislation “somewhat limits the development” of aquaculture.

He explained that the lack of a proper legal framework makes it difficult to grant long-term concessions, which are essential for investments that take 10 to 15 years to recover. In this regard, he stressed the need to simplify requirements, attract investment, and support the sustainable growth of aquaculture in the country.

The algae which has been creating problems for salmon farms in the south of Norway appears to be finally on the way out – but not before it has caused a lot of damage.

The Norwegian Institute of Marine Research said that the concentration of the Pseudochattonella algae has decreased significantly in all areas.

It is thought that high winds over the Easter weekend, including those from storm Dave which swept across Scotland and out towards Norway, are the main reason why the algae appears to be dispersing.

Chile’s fisheries authority, Servicio Nacional de Pesca y Acuicultura (Sernapesca), held a coordination meeting with salmon producers and aquaculture service providers on April 8 to address an ongoing harmful algal bloom (HAB) in southern Chile.

The bloom, caused by the microalgae Heterosigma akashiwo, has been present since March and is affecting 11 farming sites located in Salmonid Concession Groups (ACS) 1 and 2 in the Reloncaví Sound. All affected sites have activated their preventive HAB action plans.

Under an existing aquaculture pre-alert, Sernapesca has authorised fish transfers to other farming locations, emergency harvests, and extended holding periods at storage centres. The meeting reiterated procedures for operators to submit requests for these measures to the regulator in the coming weeks.

Exports of Vietnamese tuna to Spain are accelerating, with 2025 shipments projected to rise 13% year-on-year, extending momentum into early 2026.

Data from Vietnamese Customs show export turnover reached nearly US$3 million in January–February 2026, marking a sharp 101% increase compared to the same period in 2025, and well above 2024 levels.

According to Ms.Nguyen Ha, a market expert at VASEP, the rebound reflects strong European demand for tuna raw materials and processed products, positioning Spain once again as a key destination for Vietnam exports.

Despite the recent surge, the market has shown volatility. In 2024, export values remained relatively stable, while 2025 saw sharp spikes in September, November, and December, alongside notable declines in other months. This resulted in a 5% drop in early 2025 compared to 2024, before the current recovery trend took hold.
