Recent fishery research and insights:
Seafood, like all food, has environmental costs and impacts. We often report on data and science that examines seafood impacts and compare it to the impacts of terrestrial food production.
Environmental Impact Displacement in Fisheries & Food
Environmental impact displacement is an important policy concept with implications for fisheries and food.
What is the Global Footprint of Fishing?
Scientists are getting closer to figuring out how much of the world’s ocean is fished, but discrepancies in the scale and interpretation of data are producing wildly different answers with contrasting conservation implications.
A closer look at the environmental costs of food
A new paper compares and quantifies the environmental impacts of different foods, an important step for improving agricultural policy and empowering consumer choice.
Fishery management is implemented by a government or regulatory body. It dictates the rules and regulations that allow fishermen and women to harvest seafood. Effective fishery management is the most important pillar of sustainable seafood.
Fishery management is composed of small, concrete actions—which ones are best?
New research suggests a swiss-cheese model for sustainable fishery management, along with rebuilding plans.
Having our fish and eating it too: Maximizing food production and biodiversity using good management
A new paper describes how regulating specific kinds of fishing in particular areas is extremely effective at preserving biodiversity while also producing food.
Ocean Optimism?
New research says we have the policy blueprints to rebuild marine life by 2050. Decarbonization needs to happen quickly, though.
Fishery status, a snapshot look at if a fishery is sustainable or not, has been a common way to classify stocks. For example, “overfished” is a status with calculated thresholds. We cover all aspects of fishery status, including why status is no longer a good way to talk about fisheries–increasingly fisheries are classified as “overfished” due to environmental changes like climate change.
Overfished, overfishing, and rebuilding stocks
How does a fishery become unsustainable? How do we rebuild an overexploited fishery? In this post we explain overfished, overfishing, and rebuilding stocks.
How many Fisheries are Overfished?
According to the U.N., 78.7% of fish come from a sustainable fishery. Of all monitored fisheries, 66% are sustainable, while 34% are overfished.
What will Fisheries be like in 2048?
No scientist would support the assertion that all fish stocks will be collapsed by 2048. There are threats, however.
Marine protected areas (MPAs) are extremely popular with NGOs and politicians. Getting an MPA established looks good on a resume of accomplishments, but they don’t function quite like protected areas on land. Scientists are split on their efficacy. In coastal areas with sensitive habitat, they are effective, but MPAs to restrict fishing often just move fishing to other areas.
Do large MPAs benefit tuna and fishermen via spillover?
Medoff et al. 2022 claims that the largest MPA in the U.S. benefited both tuna populations and fishermen via spillover. However, the science does not stand up to careful scrutiny and we doubt their results.
Marine protected areas don’t help tuna, new paper shows
Researchers find that the Phoenix Islands Protected Area did not meaningfully boost tuna populations.
Retraction of flawed MPA study implicates larger problems in MPA science
A recent retraction in a high-profile journal raises questions about predicting the impacts of marine protected areas.
MPAs will suffer, along with the rest of the ocean, as the planet warms
A new paper mapped the effects of future emissions on marine protected areas (MPAs) around the world. The results were unsurprising—climate change threatens every MPA (and indeed every part of the ocean), with a range of impacts.
Bottom trawling is the most controversial type of fishing. It provides 26% of wild-caught seafood, but, when not managed well, has the potential to be destructive. Bottom Trawling Sustainability 101 gives a great overview.
New review shows bottom trawling is sustainable (when well-managed)
Seafood from bottom trawling can have a lower impact than other types of animal protein–especially when it comes from a well-managed fishery.
The global impact of bottom trawling visualized with data
A new paper with a cool map shows the impact of bottom trawling around the world.
How are benthic invertebrates impacted by bottom trawling?
Bottom trawling has destructive potential, but new research shows impacts can be limited with sound science and management.
Fishing has several relationships to carbon emissions. On one hand, seafood varies greatly in its carbon impacts. Some species are some of the most carbon-friendly foods to eat on the planet, others compare to beef! On the other hand, an emerging issue in fisheries and conservation is how bottom trawling impacts the carbon cycle on the seafloor. A big paper, Sala et al. 2021, made some bold claims that have mostly been disproven. We’ve covered the science of bottom trawling and carbon extensively.
Third critique of Sala et al. 2021 published by Nature
Yet another critique of the poor science in Sala et al. 2021 – the most covered fisheries research of the last decade.
Officially bogus: Bottom trawling does not release as much carbon as airline travel

Climate change is the largest threat to ocean life
New research shows that local populations of ocean animals are more vulnerable to global warming-induced extinction than terrestrial animals.

Eating Plants & Seafood
Conscious eating can and should include several different kinds of food. A plant-based diet has lower impact relative to a standard diet that includes lots of animal protein, but a diet that includes fish can have as low, or even lower impact.
