IN BRIEF - This giant, prehistoric fanged salmon is even more bizarre than scientists thought

EUGENE, Ore. — In the rivers of the ancient Pacific Northwest, a colossal salmon once swam – one that dwarfed even the largest of today’s prized catches. For decades, this extinct giant has captured imaginations as the “Sabertooth Salmon,” conjuring images of a fish with fearsome downward-pointing fangs. But a study published in PLOS ONE reveals that we’ve been telling fish tales about this prehistoric marvel all along.
Meet Oncorhynchus rastrosus, a salmon that grew to an astonishing 2.7 meters (8.9 feet) in length – nearly three times the size of the largest modern salmon. When first described in the 1970s, paleontologists found massive, isolated teeth unlike anything seen in living salmon. Without a complete skull to work from, they logically assumed these teeth pointed backward into the mouth like fangs. This led to the creature’s popular nickname and even its original scientific name, which translates roughly to “rake-toothed smilodon-fish.”
Now, thanks to remarkably well-preserved new fossils and advanced imaging techniques, researchers have discovered that we’ve had it all wrong. Those imposing teeth weren’t downward-facing fangs at all but rather sideways-pointing spikes!
“The teeth projected laterally like tusks, not ventrally like sabers or fangs,”the study authors explain in the report.
Recent advances in fishing operations largely aim to make the work easier for fishing professionals. AZTI and the University of Vigo stand out in this field with two projects focused on monitoring purse seine nets and reducing the effort involved in the albacore tuna season, respectively.
Every time a purse seiner heads out to fish, it risks returning to port with damaged gear because it lacks a system to monitor the entire net with sensors; the consequences can be even worse if that damage leads to an accident on board. To address this technological gap, AZTI has developed a new real-time monitoring system that reconstructs the geometry of purse seine nets as they are deployed in the water.

Many Americans have been cautious as to where and what they spend their money on this year, but despite those economic concerns, sushi has maintained an impressive growth path.
“Like most food categories, we've navigated challenges related to inflation, shifting consumer spending patterns, and broader economic uncertainty, but sushi has remained remarkably resilient
That’s what Hissho Sushi, which operates 3,000 sushi locations nationwide in grocery stores, college campuses, hospitals, airports, and other foodservice environments, aims to offer.

Fisheries Minister Luis Planas had convened representatives of the Spanish fishing sector to review progress on negotiations regarding the EU's multiannual financial framework—specifically concerning the European Maritime, Fisheries and Aquaculture Fund (EMFAF)—and aid to address the crisis triggered by US and Israeli attacks on Iran. However, the discussion ended up covering a wide range of topics: training, trade agreements, fishing quotas, Mediterranean regulations, and more.

Thailand has launched its first research project to farm Atlantic salmon domestically, with scientists using a recirculating aquaculture system (RAS) to assess whether commercial production is feasible in the tropical country.
The project is being led by the Faculty of Fisheries at Kasetsart University in partnership with PTT LNG. Researchers are studying salmon growth, nutrition and the economics of production to determine whether a domestic industry could be established.The first phase of the project began after 20,000 fertilised Atlantic salmon eggs were imported from Chile in early May.

Salmon farming has become one of the world’s most successful aquaculture industries. It has provided large volumes of healthy protein, created employment in coastal regions and built a global market for farmed Atlantic salmon.
For many years, the main production model has been relatively simple: produce smolt on land, transfer the fish to sea cages and grow them to harvest size in the ocean. This model has been extremely effective. It has allowed the industry to scale up and in the right locations it remains a very efficient way to produce salmon.

The Ecuadorian shrimp industry, through theNational Chamber of Aquaculture (CNA) and the Sustainable Shrimp Partnership (SSP), has formalised an alliance with Conservation International Ecuador (CI-Ecuador) to strengthen mangrove conservation and restoration efforts, promote sustainable shrimp aquaculture, and contribute to the climate resilience of Ecuador’s coastal ecosystems and communities.Through this agreement, the organisations will establish a framework for collaboration and implement joint actions under the Mangroves for Climate initiative.
The German government scraps the heavy frigate project led by Rheinmetall and opts for TKMS's Meko frigates to modernize its Navy
The German government has decided to cancel the F126 heavy frigate program—valued at approximately €10 billion—after noting accumulated delays and rising project costs. The decision marks a significant setback for Rheinmetall, which was undertaking its first major foray into military shipbuilding following its acquisition of Naval Vessels Lürssen (NVL), and it reshapes Germany's industrial strategy regarding one of Europe's largest naval defense programs.
