Develop alternative foods that taste like shrimp to help reduce demand for farmed shrimp
FWIW, given the moral ambiguity of fishing, the catch of wild animals for (shrimp) feed could be good overall for wild (aquatic) animals, instead of bad.
This and the effects of shrimp feed (crop) production on terrestrial wild animals make me somewhat inclined not to try to shift shrimp consumption towards plant-based food (substitutes or general reduction). My best guess is that crop production tends to decrease wild arthropod populations (Attwood et al., 2008, tables 3 and 4; Newbold et al., 2015), and animal products tend to decrease wild terrestrial arthropod populations more than plant-based products due to greater land use for crops per calorie or kg of protein (e.g. Our World in Data, based on Poore & Nemecek, 2018), so shifting towards plant-based would be bad for wild terrestrial arthropods, if they have bad lives or you're suffering-focused.
However, farmed shrimp/prawns may use less land than plant-based foods per gram of protein, so maybe shifting away from them would be good by reducing wild terrestrial arthropod populations, too. This is something I'd like to look more into. I imagine land use for shrimp/prawns is only so low according to these estimates because they're assuming a high rate of wild aquatic ingredients (whose impacts are morally ambiguous!). You probably can't get lower land use than tofu per kg of protein by feeding shrimp almost entirely soy and grains, because of higher losses in feed conversion than in soy processing into tofu (and tofu having similar or less land use than other feed ingredients per kg of protein).

I would be curious to know why you have decided to keep the full report private. Such that you keep track of who uses it, thus helping you assess its impact?
Nitpick. I think it would be good to include "Logarithm of" in the titles of the axes, or just keep the titles you used, but display values in kg and $ instead of their logarithms, and have the axes in a logarithmic instead of linear scale.
This graph does include wild shrimp. I've made the change to the axes you suggested and updated the figure caption to note that wild shrimp are included. Thanks for your suggestions!
I used AI to fix transcription errors, rerrarange the ideas, and suggest tweaks to the title and some sentences.
Three of the most exciting projects to come out of EA in recent years are, in a vague sense, CEA spinouts:
* Kairos is directly a spinout of CEA and now handles most support for university AI safety groups. Basically everyone I've found who knows them is really excited about what they do
* NEST is an opinionated ideas-fi...

Only a handful of animal advocacy organizations have programs aimed specifically at preventing the exploitation of farmed shrimp. We wrote this report to provide practical guidance about how to help farmed shrimp. This public summary provides an overview of the current state of shrimp farming and potential paths forward. For a deeper dive, the full 70+ page report offers concrete, strategic recommendations and more detailed insights. The full report will be most useful for animal advocacy groups, funders, and those interested in how best to help shrimp.

Summary
Shrimp production: industry numbers, trends, and practices
Shrimp aquaculture can be bad for animals, humans, and the environment
At any given time, shrimp are the most numerous farmed animal (Figure 1)
Figure 1: Estimated numbers of farmed shrimp, insects, fishes, and chickens alive on farms at any time. Data from Waldhorn and Autric (2023).
Animals like fish are caught and farmed to feed farmed shrimp, increasing the negative welfare effects of shrimp farming
Farmed insects could also become an important shrimp feed
The shrimp farming industry contributes to carbon emissions, antimicrobial resistance, food safety, and human labor and rights issues
Production and consumption are concentrated in a handful of countries
China, Ecuador, Viet Nam, India and Indonesia are top producer countries
China is also a top importer, alongside the US, Japan, Spain, and France
Demand for shrimp is increasing
As the world population grows, so will shrimp consumption
Economic growth also correlates with increased shrimp consumption (Figure 2)
Figure 2: Per capita shrimp supply vs per capita GDP. Shrimp supply includes farmed and wild-caught shrimp. Note both axes are logarithmic. Supply data from own analysis of FAO (2024) data for 2022, and GDP data from Our World in Data’s analysis of seafood consumption and GDP.
To meet demand, the industry is adopting more intensive practices
Intensive farms use higher stocking densities, presenting new welfare threats
Because the most intensive farms can be located inland and in greenhouses, farms could open in new countries that are otherwise too cold for aquaculture
Vegan or diet-change advocacy on only environmental grounds could harm shrimp welfare in the long-term by causing people to shift from eating larger-bodied animals, like cattle, to eating shrimp, which would increase the overall number of farmed animals
Shrimp advocacy: current state, opportunities, and bottlenecks
In the past few years, a handful of organizations have worked to reduce shrimp suffering
Policy advocacy led to the inclusion of decapod crustaceans in the UK Animal Welfare (Sentience) Act 2022, which legally recognized them as sentient
Retailer outreach has gained traction in the UK and Netherlands, indicating that companies are increasingly aware of growing public concern for crustacean welfare
At least six retailers in the UK and Netherlands have implemented some of the world’s first crustacean welfare policies
For shrimp, all of these policies commit to eliminating eyestalk ablation and half also plan to improve slaughter practices by electrically stunning all shrimp in their supply chains
Groups are working with producers to improve their practices, resulting in several agreements to electrically stun shrimp prior to slaughter, protocols to measure on-farm welfare, and training for farmers to monitor and improve their pond conditions
Some welfare standards are now included in certification schemes, with several prohibiting eyestalk ablation
More progress can be made. Advocates could work to:
Add shrimp welfare provisions, such as banning eyestalk ablation and enforcing humane slaughter, to aquaculture certification schemes (similar to certifying eggs as "free-range")
Encourage more retailers, especially in countries that import a lot of shrimp, to source from higher-welfare farms (similar to movement-wide efforts on cage-free eggs)—for now, this means farms that do not source from eyestalk-ablated broodstock and that humanely slaughter shrimp
Advocate for shrimp to be protected under animal welfare legislation—only a handful of countries have any mention of decapod crustaceans in animal welfare protections, and even fewer specifically apply to shrimp
Develop alternative foods that taste like shrimp to help reduce demand for farmed shrimp
To meaningfully help farmed shrimp, key bottlenecks need to be overcome:
A small scientific evidence base about shrimp’s needs means several questions remain unanswered, like what level of crowding impedes their welfare and what temperatures and enrichments they prefer
The biggest constraint to improving farmed shrimp lives right now is funding for the movement. Supporting shrimp work right now could provide much-needed stability to this nascent work and significantly increase the chances of the movement gaining critical momentum
We believe that supporting shrimp welfare is currently one of the largest opportunities for animal funders to have the greatest marginal impact
Despite these constraints, many options for helping shrimp remain on the table. Advocates and funders should apply the precautionary principle and act on existing evidence to help shrimp sooner rather than later.
