IN BRIEF - Mass proliferation of reproductive stem cells 1 to 1700 rainbow trout hatching
JAPAN
Monday, August 03, 2020
The team of Professor Goro Yoshizaki (Fish Aquaculture) of Tokyo University of Marine Science and Technology said that he succeeded in the world's first successful growth of large numbers of reproductive cells, which are the source of rainbow trout eggs and sperm, in a test tube. Published in "Communications Biology". Eggs and sperm were made from only one male stem cell and 1700 hatched. It is steadily growing into an adult fish and is expected as a technology that enables mass production while protecting valuable fish from fish resources.
Prof. Yoshizaki explained that he would like to contribute to aquaculture production and conservation of endangered species. "A salmon or trout close to rainbow trout can be used for conservation projects in a few years. Application to bluefin tuna will be realized in about 5 years. I want to aim for."
The program, funded by RVO and EMFAF, will remain open until September 3, 2026, to mitigate the impact of rising fuel prices on Dutch vessel owners.
The Rijksdienst voor Ondernemend Nederland (RVO) is keeping open until September 3, 2026, a dedicated support line designed for fishing vessel owners affected by escalating fuel costs. The scheme has a total budget of €13.5 million, co-funded at 70% by the European Maritime, Fisheries and Aquaculture Fund (EMFAF), with the remaining 30% provided by the Dutch Government.
The call for applications is aimed exclusively at vessels registered as fishing units in the Netherlands and provides differentiated aid based on license type, engine power, fishing gear, and targeted activity. Eligible categories include North Sea shrimp (Crangon crangon) fishing, mussel (Mytilus edulis) and oyster (Ostrea edulis) farming, as well as various coastal and trawl fishing operations.
The first application window opened on August 20 and will close on September 3, 2026, at 17:00 hours. Compensation is calculated based on liters of diesel supplied between March and June 2026, with reference rates ranging from €0.21 to €0.45 per liter, depending on the month of supply. The maximum grant per vessel ranges from €5,000 to €189,000.
External experts have visited the Falkland Islands (Islas Malvinas) to present differing perspectives during an ongoing public consultation on the potential introduction of commercial salmon farming.
Initiated by Unity Marine—a joint venture aiming to establish an annual production of 50,000 tonnes—the consultation saw the developer bring in Canadian aquaculture specialists Dr. Gary Marty and Bernie Taekema. The experts detailed environmental assessment models, biosecurity controls, and site selection criteria based on British Columbia's regulatory framework.
Conversely, opposition campaigners from Salmon Free Falklands brought in Louise Cherrie, a former environmental authority insider from Tasmania, to highlight concerns regarding local governance, carrying capacity, and long-term marine ecosystem risks. Public engagement on the matter continues through October 30, 2026.
New Dalian subsidiary will integrate seed, breeding, R&D and marine aquaculture
Zoneco Group will establish Zhangzidao Seed Technology with RMB 20 million (US$2.97 million) in capital, consolidating seed, genetics and R&D. Its existing Qingdao Qianyan unit posted RMB 115.45 million in revenue and RMB 10.80 million net profit in H1 2026.
The Chinese firm Zoneco Group announced plans to establish a wholly-owned subsidiary focused on consolidating its operations in seed development, genetic improvement, scientific research, and marine aquaculture.
Faroese and foreign vessels intensify operations in international waters north of the archipelago
Mackerel fishing is picking up around the Faroe Islands. Greenlandic vessels Polar Amaroq and Polar Princess landed or scheduled 600 and 700 tonnes in Kollafjørður, while Faroese vessels joined the fishery. On August 25, Norðingur landed 120 tonnes at Pelagos in Fuglafjørður before returning to the grounds.
UF professor honored for his global contributions to aquaculture economics and policy
James Anderson, professor at the University of Florida, was named a 2026 World Aquaculture Society Fellow, recognizing his leadership in aquaculture economics, markets and policy. His work includes the Aquaculture Performance Indicators (APIs), a framework assessing economic, environmental and community outcomes across 80+ aquaculture systems worldwide.
Anderson’s own interest in the discipline started not with economics, but with the first fish tank he owned as a child.
TS3 system provides GPS updates every 30 seconds for small-scale coastal fleets
Fiji is piloting Triton’s Spear (TS3), developed by Japan’s Ocean Solution Technology with JICA support. The solar-powered system tracks vessels via GPS every 30 seconds, aiming to improve fisher safety, coastal resource management and sustainable fisheries across the Pacific.
Businessman Álvarez Castellano says the magistrate left unsigned the document that would allow the *J. Barreiro* to resume fishing operations.
Although the Argentine courts ruled to lift the suspension imposed on the *J. Barreiro*—a vessel belonging to the Conarpesa group (42% owned by the Galician firm Wofco)—the ship remained detained as of Tuesday, according to Fernando Álvarez Castellano, director of the Argentine fishing company. He attributes the delay to the missing signature of the judge who originally halted the vessel; she is no longer handling the case after the businessman announced legal action against her.

DSM-Firmenich?Animal Nutrition & Health today announced an update to its Digital SalmoFan software, adding a new algorithm designed to accurately measure trout fillet colour for partners across the entire value chain.
The Digital SalmoFan is a portable device that measures the colour of salmon and trout fillets digitally, using a numeric scoring system. This latest innovation builds on the foundations of the existing physical SalmonFan colour chart widely used in the global salmon industry for fillet colour measurement.

Pakistan’s seafood exports to China rose sharply to US$220 million during the first seven months of the current year, registering a 41% year-on-year increase from the corresponding period last year, according to the General Administration of Customs of China.
The growth reflected strong Chinese demand for a diverse range of marine products, particularly frozen fish, cephalopods and live crustaceans. Miscellaneous frozen whole fish led individual categories, generating US$40.04 million from 19,834 tonnes. Frozen cuttlefish and squid varieties together contributed US$36.39 million.
Frozen sardines and sprats generated US$19.49 million from 22,458 tonnes, while live and chilled mud crabs brought in US$18.70 million. Other significant exports included frozen octopus worth US$9.16 million, fish fillets and meat at US$7.71 million, frozen shelled shrimp and prawns at US$6.86 million, and flatfish at US$5.71 million.
Atlantic salmon, salmon fillets and smoked salmon are among seafood products included in Canada's latest retaliatory tariff package.
Canada will impose a 25% tariff on Atlantic salmon and a range of other seafood products originating in the United States from September 8, as part of its latest response to US trade measures.
The United States remains a relatively small producer of farmed Atlantic salmon compared with Canada, Norway and Chile, but it does have commercial production.
Atlantic Sapphire operates a land-based salmon farm at Homestead, Florida, where it harvested 5,096 tonnes in 2025.
