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.

Our primary goal in 2021 is to improve the lives of 500,000 fish by enabling higher welfare practices for farmed fish in India. Currently, we’re aiming to raise a remaining $140,000 to enable this impact. See more in our FAQ below.

What is your current fundraising goal?

We’re currently looking to fill a $140,000 funding gap for 2021.


What will you do with this money?

Additional funding right now will primarily go towards supporting our work to secure 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?

We are currently estimating our first-year cost-effectiveness at about 1-2 fish helped per dollar. By helped, we mean living significantly better lives due to improved water quality. This figure should not be taken literally, but we believe it is roughly to the same order of magnitude.


We hope and expect that our cost-effectiveness will increase by one or two orders of magnitude in the coming few years, as we shift our efforts from building a successful model to scaling it.


We will continue to re-evaluate our cost-effectiveness periodically.

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 tens of 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 corporate supply chains and governmental bodies, as we are working towards, allows us to impact a massive number of farms, each with thousands or tens of thousands of fish, without ever setting foot on the ground (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?

Fish Welfare Initiative is currently a registered not-for-profit organization in the US, and is in the process of gaining our 501(c)3 status. We can however accept tax-deductible donations in the US, the UK, and the Netherlands -- see above.


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.


I’m interested in making a donation $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 made out to "Players Philanthropy Fund DBA Fish Welfare Initiative." They should then be mailed to our fiscal sponsor:
