FISHING
The USA imports far more seafood than it produces. The government has therefore implemented a massive expansion of aquaculture: approved by economists but vilified by scientists.
Fishing and aquaculture activities generate 4,600 tonnes of plastic waste per year. This study describes a system for recovering floating debris generated by tuna fishing.
More and more fish statistics are being compiled. They enable us to understand reproduction and migration patterns, and optimize sustainable, responsible fishing to protect them. This study is yet another example.
Replacing meat with fish or seafood could reduce the global carbon footprint without compromising nutrition. Of course, these products must come from sustainable and responsible aquaculture or fisheries.
This study shows that small-scale, local, sustainable and responsible fisheries can ensure food security. The case chosen to illustrate this study is Norway.
"The creation of marine protected areas shows positive results on populations of threatened fish such as tuna. This article presents the case of Hawaii, where the statistics are very encouraging."
Shellfish are perhaps the key to a suitable protein diet for the world's population. Maintaining their well-being in aquaculture raises questions, and research on this subject is is multiplying.
Fishing boats from Spain, China, Taiwan and the USA tend to mask their position when sailing. This poses obvious tracking problems and hinders the fight against illegal fishing.
Catch rates are falling, but demand for fish is rising. Scientists have concluded (with regard to the directives adopted in China) that aquaculture needs to be developed and that the ecological data for each species needs to be better taken into account.
Everything that comes out of a fishing net is classified as a "fish". However, the nutritional content of different species varies widely. 2,348 species were studied in order to identify the most nutritious fish in 39 of them.
With global warming and overfishing, fish stocks are dwindling. Aquaculture is probably a solution to continue feeding mankind without causing biodiversity to plummet. Report from the PACA region.
This study shows the impact of predators on fish communities in Chinese rivers. Predation is a key piece of data, poorly estimated, that needs to be integrated into statistical monitoring for biodiversity protection.
Marine protected areas mitigate the loss of biodiversity suffered by the ocean in the face of marine heat waves. They also enable biodiversity to be restored 75% more quickly than in unprotected areas.
Octopus is fished in a fairly artisanal and sustainable way throughout the world. It is also rich in nutrients that are beneficial to human health. Its small-scale capture could be a tool for the development of sustainable and responsible fishing.
The use of microalgae in the nutrition of aquaculture fish could help reduce fishing pressure. This article shows positive results, but also raises long-term questions.
While fish farming is one of the most environmentally-friendly ways of producing protein, there seems to be a major problem. A small fraction of the Earth's surface bears almost all the environmental burden of fish farming.
Yellowfin tuna is threatened by overfishing. The study of fishing data has revealed the habitat preferences and migration trajectories of tuna according to their mass. Essential results for the protection of these animals.
Ocean warming will not completely destroy coral reefs, but it will greatly alter their biomass. The impact on fishing resources could be very significant.
Marine protected areas fuel the debate: do they enable co-benefits between fish and humans? Or are they just compromises? This study shows that their implementation also brings many benefits to humans.
According to some estimates, tuna stocks are set to increase in areas where deep-water mining is planned. This would lead to overlapping activities (fishing and drilling) and therefore a high risk of conflict.
Environmental DNA is collected from the environment rather than directly from an organism. Its study is a reliable, rapid and precise method for measuring the state of fish stocks as part of fisheries monitoring.
This scientific study aims to provide reference points for estimating sustainable stocks of species fished on reefs. This helps determine the health of the ecosystem and the quantity of fish that can be harvested sustainably.
Not all rainbow trout populations have the same resistance to rising temperatures, depending on their geographical origin. A fact to be be taken into account in the preservation of this commercial species.
Scientists are studying the diets of sardines, sprats and anchovies in the Mediterranean (and the overlap of their food webs). The aim is to be able to predict population dynamics and manage fishing sustainably.
The impacts of marine heat waves on the main predator distributions are variable but predictable. A tool developed by scientists can predict these dynamics in near-real time.
This article shows how an "offshore wind farm + aquaculture farm" combination could meet the environmental and food challenges of the future. The aquaculture in question would be kelp and mussels.
Fishing subsidies in the Indian Ocean exacerbate inequalities in access to nutrients (mainly seafood) and accentuate overfishing to the detriment of sustainable fishing.
