These findings are promising and will likely spur future research into the impact of no-fishing zones on other migratory species. No-fishing zones protect vulnerable species, reducing the pressure from anthropogenic threats like overfishing, and allowing them to increase their population size. Papahānaumokuākea was created in 2006 and is now the largest no-fishing zone in the world following its expansion in 2016. It was created to not only protect its biological resources but also its cultural value; Native Hawaiians consider this area to be sacred and as such it is co-managed by Native Hawaiians, the state of Hawaiʻi, and the federal government. Industrialised methods allowed fishing companies like Ricardo Fuentes to capture enormous numbers of tuna using purse seiners, to provide enough live bluefin tuna to stock ranches with hundreds of tonnes of tuna from just one trip. While industrial giants used technology to detect areas where the fish are, traditional fishers catch one fish at a time and are led to their prey by seagulls.
New research shows that a large marine protected area in Hawaii led to recovery and spillover of migratory species.

Additionally, the positive results seen in this study aren’t necessarily an isolated global incident.
Freshly caught the previous day, are being taken out of the freezer trucks, as forklift trucks raise plastic containers into a giant grinder. Coastal fishermen need to know the flounder season is closed for recreational and commercial fishermen Oct. 15 through Nov. 30. On Wednesday state Enforcement Division agents made their first case of the closed season on flounder when they cited three folks in Plaquemines Parish for taking the “flat” fish.

Jun Hoshikawa has witnessed changes to the local catch firsthand from his home on Yakushima island, a UNESCO world natural heritage site of natural beauty where he has lived for four decades. Kochi’s arc-shaped bay has traditionally been a fertile fishing ground, but bigger fish could be a warning rather than a blessing. The average surface temperature of the bay in winter has risen 2°C over the past four decades — meaning there is more food for the fish.
Catch rates for bigeye tuna (also known as ʻahi) increased by 12%; catch rates for all fish species combined increased by 8%. The team used data collected from fishing boats and found that the catch rate of yellowfin tuna increased by 54 percent in the fishable waters close to the Papahānaumokuākea protected area since 2010. Additionally, the catch rates for bigeye tuna increased by 12 percent and it was 8 percent for all fish species combined in the years since the MPA was expanded. A study published this week in the journal Science finds that carefully placed no-fishing zones like Papahānaumokuākea can help restore tuna and other large fish species. “We show for the first time that a no-fishing zone can lead to the recovery and spillover of a migratory species like bigeye tuna,” says co-author John Lynham, a professor in the Department of Economics at the University of Hawaiʻi at Mānoa’s College of Social Sciences, in a press release.
After all, news coming from all sectors of outdoors suppliers is a hint of the increasing participation of women in the shooting sports. If you haven’t seen the numbers, then know women make up the largest increases in firearms purchases and trips to indoor and outdoor ranges. “Unfortunately, most Japanese people haven’t yet noticed the subtle changes in the seafood they’re eating, although I expect that to change in the coming years,” he added. “The northern shift in habitats is likely to become a wider trend for many marine species as a result of rising sea temperatures,” said Hoshikawa, a former executive director of Greenpeace Japan. Shin-ichi Ito, a professor at the University of Tokyo’s Atmosphere and Ocean Research Institute, said that rising sea temperatures meant some species, including yellowtail and Spanish mackerel, were being found in unusual locations.
Overfishing and exploitation soon gave way to ‘tuna wars’, as competition for the species became intense. Calls for quotas, imposed by the International Commission for the Conservation of Atlantic Tunas , eventually led to the introduction of the total allowable catch . When governments decided to reduce tuna fleet capacities by 25%, smaller fisherman cashed out their quotas to the big players. Even the resultant water from this process gets turned into a demi-glace treated in pretty much the same way as a fish-stock, the water being allowed to evaporate, so that the resultant protein gets added to the solids inside the disc-dryer. “We’re using the raw material entirely,” says ARL’s technical consultant Tristan Camilleri, proud to explain how five tonnes of raw material will be processed at each hour, to produce an annual output of 450 tonnes in fish meal, and 550 tonnes of oil each year – conservatively valued at €3 million in exports.
We are getting high yields, with huge Omega values, and producing best-in-industry quality fishmeal,” he says, handing me the bottarga-like dust of tuna granules. A future in which crustaceans have disappeared from the menu seems unthinkable, but ocean acidification risks making that a reality. A rise in seawater temperature makes it more difficult for shellfish and crustaceans to form calcium carbonate, adversely affecting the growth of popular seafood such as scallops, clams and oysters, as well as crabs and shrimps. Aiko Yamauchi, vice president of Seafood Legacy, a Japan-based consulting firm that supports sustainable seafood businesses and environmental groups, said that catches of species venerated by Japanese have been in steep decline since 2014.
In 2021 an increase in tuna quotas led to an almost 15% increase of bluefin tuna, generating €25 million more in Maltese domestic output, above the €179 million registered in 2020. Today Malta is one of the largest producers of bluefin tuna in the Mediterranean and Atlantic, and the top producer in the European Union. “Ask a Japanese person what their view of Maltese tuna is and they will tell you it is the best, the very hallmark of good quality,” Gouder says. ARL, which is owned by ranching giants AJD Tuna, Fish And Fish and MFF Limited, is the showcase of Malta’s tuna lobby, the Maltese Federation of Aquaculture Producers. Now it hopes it can use its sprawling 3,000sq.m land to a business incubation centre focusing on the aquaculture and marine industry, for scientific researchers.
