We work to change the world for fish by identifying high-impact welfare improvements, and then implementing them through institutional commitments--with the ultimate goal of improving the lives of billions of fish. Your support is a fundamental part of achieving that impact.


To learn more, see our FAQ.


For donations of $1,000 or more, or to make a tax-deductible donation in the UK or the Netherlands, see below.



What is your current fundraising goal?

We’re currently looking to fill a ~$100,000 funding gap for 2021.


What will you do with this money?

Additional funding right now will primarily go towards supporting our work to secure and implement welfare commitments for farmed fishes in India. You can learn more in our 2021 plan and budget.


How cost-effective is a donation to Fish Welfare Initiative?

One way of estimating FWI’s rough cost-effectiveness is to divide the total number of fish we expect to help through our commitments (~9 million) by the amount of money we expect to have needed in total for its procurement and implementation (we’ll roughly estimate that at $566,000, which is the sum of the money we spent to get FWI to the commitment [$166,000] and $100,000 a year for the next five years to implement). This calculation results in 15 fish helped per dollar. You can see the welfare improvements we are making here, although at this stage we, unfortunately, do not think it makes sense to estimate the magnitude of the impact on a per fish basis.


This estimate is of course imperfect, and the true figure could be significantly higher or lower. However, we expect that the rough order of magnitude is correct, and we further expect that our cost-effectiveness will increase as we increase our efficiency.


In sum, there’s some preliminary evidence to show that FWI’s work is very cost effective, although this evidence is very tentative. We hope to gain more evidence as we progress.

Improve the lives of billions of fish? Is that even possible?

We dream big, but yes, we certainly think so. This is partly a testament to the vast scope of aquaculture: smaller farms hold thousands of fish, while the largest ones hold over a million. Therefore, with fish, even working at just the farm level means that you can impact the lives of a massive number of individuals. Going further, partnering with institutions such as corporations and NGOs allows us to impact a massive number of farms, each with thousands or more fish (analogously, see the impact of cage-free corporate advocacy for chickens). Over the course of years, this upstream approach is how we aim to improve the lives of billions of fish.


Is FWI a registered charity?

Yes, as of January 2021 Fish Welfare Initiative is a registered 501(c)(3) non-profit organization (#85-2065536). Your donation is tax-deductible in the US to the extent allowable by law.


We are also currently registering a branch organization in India.


What are the best arguments against donating to FWI?

You made it this far, so we’re assuming you already believe that fish have significant moral value (if not, see Brown 2014). Putting this objection aside, we think one of the strongest arguments against our work is the experimental nature of it: very few organizations have worked on fish welfare previously, and hardly any in India. Additionally, the base rate of failure with startups is high. Although we aim to reliably demonstrate our impact in the future, at the moment we believe that FWI should best be thought of as a higher-risk, higher-reward donation opportunity.

We believe that our recent commitments, which will impact several million fishes, are the most promising evidence yet in favor of our impact. However, although we have the formal commitment the implementation has yet to begin, and will no doubt bring many difficulties.

I would like to make a tax-deductible donation in a country that is not the US. How do I do that?

Currently, donations to Fish Welfare Initiative may only be tax-deductible in the US, UK, and Netherlands. For your donation to be tax-deductible in the UK or Netherlands, you will need to donate through the Effective Altruism Funds.


I’m interested in making a donation of $1,000 or more to FWI. What should I do?

You should reach out to us so that we can ensure that FWI is a good organizational fit for you and that if so, you make your donation via the most efficient avenue.

I would like to mail in a check. How should I do that?

Checks should be mailed to the following address:

Fish Welfare Initiative Attn: Nick Hollman, Trustee

5760 Bittersweet Pl.

Madison, Wisconsin 53705



Which other organizations should I support?

Our team members are proud to support the work of ACE-recommended and GiveWell-recommended organizations, and we encourage you to do the same. We believe in the impact of these organizations and aim to replicate their successes.
