Our goal is to improve the lives of as many fish as possible. Below we estimate how many fish and shrimp we have already helped.
Areas of Impact
Fish Potentially Helped
This includes all the fish we have helped already.

How we define fish potentially helped
In “fish potentially helped”, we include all the fish living in a pond where we have implemented a welfare improvement that we believe otherwise would not have been implemented. To get the number of fish helped per dollar, we divide the sum of fish living in a pond with welfare improvements by the total expenses we have had as a charity so far.
Currently, most fish we help result from working with farmers through the Alliance for Responsible Aquaculture. Specifically, they live on farms where we believe we have been responsible for stocking density and/or water quality improvements.
Examples of fish potentially helped:
A farmer planned to stock 3,500 fish per acre. After working with us, he realized the benefits of stocking at most 3,000 fish per acre. Stocking fewer fish gives the fish in the pond more space, which in turn helps curb disease outbreaks and poor water quality. Thus, the fish in this pond live better lives.
In another pond, we detected dissolved oxygen levels lower than specified in the ARA commitment. We advised the farmer to remove debris at his pond and turn on his aerators. The follow-up measurements showed a significant increase in dissolved oxygen, giving the fish in his pond better lives.
A farmer experienced low dissolved oxygen and followed our requirements for water exchange. The next day, dissolved oxygen levels were in the ideal range per the ARA commitment. By improving oxygen levels in his pond, this farmer give the fish a better quality of life.
Shrimp Potentially Helped
Note: We are much less certain about the number of shrimp helped and the impact our interventions have on shrimps' lives.

How we define shrimp potentially helped
In “shrimp potentially helped”, we include all the shrimp living in a pond where we have implemented a welfare improvement that we believe otherwise would not have been implemented. To get the number of shrimp helped per dollar, we divide the sum of shrimp living in a pond with welfare improvements by the total expenses we have had as a charity so far.
Currently, most shrimp we help result from working with farmers through the Alliance for Responsible Aquaculture. Specifically, they live on farms where we believe we have been responsible for stocking density and/or water quality improvements targeting the fish in the pond. As such, the impact we have on shrimp is indirect through targeting fish.
Limitations of our numbers
We don’t assess magnitude. Numbers on fish potentially helped do not consider the degree to which they were helped, though this is something we plan to estimate in the future.
We generalize. It is possible that some fish counted may not have suffered in the absence of our intervention. For example, water quality is dynamic depending on where fish are in the pond. Thus, we do not know with certainty that all individuals would have suffered under water quality levels we deem inadequate.
We only count the fish we know of. It is common for there to be fish within a pond that have not been intentionally stocked by the farmer, such as invasive fish who enter the system through in-flow or fish that were not successfully removed in previous harvests. We expect that in almost all cases our improvements will also positively improve these fishes’ lives. However, we do not currently have a way to account for our impact on these individuals, so they are excluded.
We focus on fish. We work with farmers farming fish or shrimp, or both in polyculture. Thus, our welfare improvements affect both fish and shrimp. We see the fish lives we improve as our primary area of impact because our interventions are targeting fish species. We are much less certain in the impact we have on shrimp, even though farmers stock a lot more shrimp in each pond.
We have limited shrimp welfare knowledge. We know much less about shrimp welfare. The focus of our improvements and measurements have been on fish. As such, we are less confident that shrimp have been significantly positively affected by our interventions than we are for fish. However, we are relatively confident that the improvements we make that target fish welfare can benefit shrimp. Mainly because improving water quality parameters like dissolved oxygen, temperature, and pH is essential for shrimp welfare.
Thank you for making this impact possible.
