Under Heat and Acid Treatment: Rheological and Calorimetric Analysis
Jumbo squid mantle muscle gels were prepared by using the one-step (90 °C/30 min) and the two-step (30 °C/1 h + 90 °C/30 min) heat treatments (HTs) with and without the addition of d-isoascorbic acid (IAA). Reactive sulfhydryl (-RSH) content, SDS-PAGE protein profiles, gel-forming ability in terms of their texture profile analysis (TPA), folding test (FT), and water holding capacity (WHC) were evaluated on experimental gels.
Additionally, the rheological and calorimetric behaviors of previously prepared sols were monitored. The –RSH content of gels showed no statistical differences (p = 0.05) due to the effect of HT; however, their content was reduced by 18.4% by the addition of IAA.
The TPA showed changes only in cohesiveness (p < 0.05). The FT evaluation indicated that all gels were A–B grade. The WHC of gels increased with the two steps of HT but decreased with the addition of IAA. The rheology and calorimetry of sols remained without major variations.
The cod fishing fleet welcomes the fact that the European Commission is finally "consistent with its words," although the new measures could generate "a supply problem."
As its name indicates, the Melkart-5 is the fifth vessel in the large family of trawlers belonging to the Russian fishing company Murman Sea Food, one of the most important firms in the sector in the country, operating from the port of Murmansk, Russia's largest in the Arctic. The company was sanctioned in May 2015 by the Council of the European Union along with Norebo JSC, another long-established player in the nation's fishing industry. Both allegedly collaborated with the Kremlin by sponsoring various "destabilizing activities" against the EU27. Acting as a kind of undercover agent, they were caught red-handed amid escalating tensions between the two powers, three years after the outbreak of war in Ukraine.

The Coalition for Fisheries Transparency (CFT) has called on parliamentarians to place fisheries transparency at the centre of efforts to build a sustainable future for the UK fishing industry.
The call comes amid concerns over declining fish stocks and continued illegal fishing activity. According to the coalition, 35% of global fish stocks are fished unsustainably, while half of the UK’s ten most important fish stocks are either critically low, overexploited or both.
The coalition says implementing the Global Charter would promote transparent, equitable and well-governed fisheries while helping eliminate harmful fishing practices, labour abuses and illegal activity across global seafood supply chains.
Skretting has introduced phytocomplexes into its health feed products for Norwegian salmon, marking the first commercial use of the plant-based ingredient combinations in the country’s salmon farming sector.
The feed manufacturer said the initiative is aimed at helping fish cope with chronic inflammation, an issue that has become an increasing challenge for Norwegian salmon producers in recent years and has been linked to reduced robustness and higher mortality.Unlike feed additives based on isolated compounds, phytocomplexes combine multiple bioactive substances derived from plants.

The Brazilian Aquaculture Association (PEIXE BR) has highlighted two important advances achieved in recent days regarding the import of tilapia fillets from Vietnam, the result of mobilization and collaborative work across the entire national aquaculture production chain.
On June 2, the Government of the State of São Paulo announced the publication of a decree establishing an ICMS tax on imported tilapia fillets; a measure that, according to the Association, “represents a significant step in the pursuit of greater fiscal balance and fairer competitive conditions for Brazilian producers.”

NOAA strengthens commitment to aquaculture through new cooperative institute. More than $13M invested in research partnerships to bolster American seafood competitiveness.
NOAA announces the University of New Hampshire as host institution for the new NOAA Cooperative Institute Fostering Aquaculture Research and Markets (CIFARM) to expand NOAA’s impact and strengthen efforts to boost American seafood competitiveness. After a highly competitive application process, this new five-year cooperative institute will harness partnerships with cutting-edge researchers to advance American marine aquaculture.
RaySon algal oil, an alternative source of omega-3 specially for salmon feed, improves the quality of the final product for consumers and boosts the immune system.
Xiamen Huison Biotech Co Ltd have been dedicated to the research and production of algal oil for over 20 years, with rich experience and advanced technology.
These benefits make DHA-rich feeds a key factor in improving both the health of farmed salmon and the quality of the final product for consumers.

Strong biological development has led to higher salmon production and pushed prices down this year. Arctic Securities now believes in better market balance.
The market-influencing spot price of Norwegian farmed salmon will bottom out at NOK 53 (£4.22) per kilo in July and August, and will average NOK 72 in the second half of the year, a seafood analyst believes.
While weaker prices are often associated with challenges in the industry, Nordby believes that the explanation this time is largely the opposite.High harvest weights, high superior share, and low mortality in Norway have contributed to more salmon coming on to the market.

A few months before the event, the Center for Applied Research, CIA-INCAR², confirmed the sponsorship of the National Fisheries and Aquaculture Service (Sernapesca) for the International Conference SRS2026. This will be the first international meeting dedicated exclusively to piscirickettsiosis, a disease caused by the bacterium Piscirickettsia salmonis. This disease causes significant economic losses for Chilean salmon farming and is currently generating increasing interest in other countries of the Northern Hemisphere.

A maximum of 250 daily permits and a limit of 10 permits per month per holder of a valid first-class recreational maritime fishing license are the key points of the new resolution adopted by the Government of Cantabria for recreational octopus (Octopus vulgaris) fishing in Cantabrian waters this year. The season will begin on July 1 and will run until September 30, in accordance with current regional regulations governing this activity.
The resolution, published in the Official Gazette of Cantabria (BOC), aims to reconcile the enjoyment of recreational fishing with the sustainability of the resource and the preservation of the species.
