What citizen science fishing projects are and how to join one
Citizen science fishing projects invite anglers to collect data while they fish — recording water temperature, fish species, size, and location — then share that information with researchers who use it to track fish populations, water quality, and ecosystem health. You fish as you normally would, but you also become part of a research effort that informs conservation decisions and fisheries management.
Most projects are free to join. You contact the organization running the project, learn what data they need and how to record it, then report your catches through a form, app, or email. Some projects ask you to submit photos or measurements; others just need basic details. The work happens on your own schedule, during your regular fishing trips.
These projects exist because professional researchers cannot be everywhere at once. A network of anglers fishing different waters across different seasons generates data that would cost far more to collect any other way — and the data is more honest, because it comes from people actually fishing, not from a survey.
Key Takeaways
- Citizen science projects ask you to record species, size, water temperature, and location during normal fishing trips, then submit the data to researchers.
- Most projects are free and work through a simple form or app; some provide training or equipment to help you record data accurately.
- Your data feeds into research on fish populations, climate change impacts, invasive species, and water quality — information that shapes fishing regulations.
- Projects vary by region and target species, so finding one that matches your local waters and what you fish for takes a few minutes of searching.
Finding a project that matches your waters and target species
Start by searching "[your state] citizen science fishing" or "[your state] fish monitoring." Most states run at least one project through their fish and wildlife department. Some are statewide; others focus on specific rivers, lakes, or regions. The National Phenology Network and iNaturalist both host fishing-related observations, though they cast a wider net than fish-only projects.
If your state's department of fish and wildlife has a website, look for a "research" or "citizen science" section. Many link directly to active projects. If you fish for a particular species — trout, bass, walleye, salmon — search that species name with "citizen science" to find projects focused on it. Regional fishing clubs and conservation groups often run their own projects too; ask at a local tackle shop or check the websites of groups working on waters you fish.
Once you find a project, read what data they need and how often they want reports. Some ask for every fish you catch; others want only certain species or only fish above a certain size. Some need detailed measurements; others just need a count. Pick a project whose requirements fit your fishing style, not one that will feel like homework.
What data you will record and how to record it accurately
Most projects ask for the same core information: species, date, time, location (often as GPS coordinates or a named spot), water temperature, and fish size. Some add questions about water clarity, weather, or what bait or lure you used. A few ask for photos or fin clips for genetic analysis, though that is less common.
Accuracy matters because bad data wastes researchers' time. Before you start, the project will show you how to identify the species you are reporting — often with photos or a key that walks you through distinguishing marks. If you are unsure, most projects say to leave that fish out rather than guess. For size, they will tell you whether they want length, weight, or both, and whether to measure from the mouth or the nose. For location, they usually want either GPS coordinates (your phone can provide these) or the name of the specific spot — "the bend below the dam" rather than "the river."
Keep a small notebook in your tackle bag to jot down details while you fish. Water temperature is easiest to record right away with a thermometer; you can note it in the notebook and enter it into the form later. If the project uses an app, you can often fill it out on your phone between casts. If it uses a paper form or email, take photos of your catch with your phone so you have the details to reference when you get home.
Projects organized by region and what they track
The Angler's Atlas, run by the Coastal Conservation Association, focuses on saltwater species along the Atlantic and Gulf coasts. Anglers report catches of redfish, snook, tarpon, and other species, and the data feeds into research on population trends and the effects of fishing pressure.
Trout-focused projects vary by state. Many states run their own creel surveys — formal data collection on trout streams — and some invite citizen participation. The Trout Unlimited network sometimes coordinates local monitoring efforts. Coldwater stream projects often ask for water temperature and macroinvertebrate observations (the small creatures in the water that indicate health) alongside fish data.
Walleye, pike, and bass projects tend to be regional. The Great Lakes Fishery Commission coordinates monitoring across the lakes, and individual states run projects on major inland lakes. Salmon projects exist in the Pacific Northwest and Great Lakes, tracking returns and population recovery.
Invasive species projects — tracking zebra mussels, Asian carp, or other non-native fish — often welcome reports from any angler who encounters them. These projects move fast because early detection matters; if you catch something unusual, reporting it quickly can help managers respond.
How your data is used and what happens after you submit it
Once you submit your data, the research team reviews it for accuracy and enters it into a database alongside data from other anglers. They look for patterns: whether a species is becoming more or less common, whether fish are growing larger or smaller, whether populations are shifting to different depths or times of year. Some projects publish annual reports showing what the data revealed; others feed the information directly into fisheries management decisions.
Your data might influence the size limits or season dates for the fish you catch. It might show that a species is recovering faster than expected, or that an invasive species is spreading and needs urgent attention. It might reveal that water temperature is rising, which affects which species can survive in a particular lake. Researchers also use citizen data to validate their own field work — if your observations match what they are seeing, it confirms their findings.
Most projects keep your data public or share it with other researchers. Some ask permission before using your data in a published study; others assume consent when you submit. Read the project's data policy before you start so you know what to expect.
Training and support from project organizers
Most projects provide some form of training, even if it is just a written guide or a video showing how to identify species and take measurements. Some hold in-person workshops at the start of the fishing season. A few mail out identification cards or thermometers to make data collection easier.
If you are new to a project, start by contacting the organizer with questions. They want you to succeed and will walk you through the process. Ask how to handle edge cases — what to do if you catch a fish you cannot identify, or if your thermometer breaks, or if you fish a spot that is not on their map. Most projects have a contact email or phone number for exactly this reason.
Some projects offer training on specific skills. Trout projects might teach you to identify aquatic insects. Saltwater projects might show you how to measure a fish without a ruler. If the project offers training, take it. The time spent learning to record data correctly saves time later and makes your data more useful.
Connecting with other anglers in the project and at local events
Many citizen science projects host meetings or fishing events where participants gather to fish together and share what they have learned. These are good places to meet other anglers interested in conservation, to ask questions face-to-face, and to see how experienced participants record their data. Some projects organize group outings on specific waters; others hold workshops or talks at fishing clubs.
If your project does not organize events, consider starting a local group. Email the project coordinator and ask if other anglers in your area are participating. Many projects will help you connect with them. A small group fishing the same water and sharing data can build momentum and make the work feel less solitary.
Citizen science projects often connect to broader conservation efforts in your region. You might meet people working on habitat restoration, invasive species removal, or stream cleanup. Many anglers who start with data collection end up volunteering for these projects too, because they care about the water they fish.
Frequently Asked Questions
Do I have to fish a certain way or use certain gear to participate?
No. Most projects want data from anglers fishing however they normally fish — fly rod, spinning rod, net, whatever. Some projects ask you to note what bait or lure you used so they can track whether certain methods catch different sizes or species, but that is for context, not a requirement. Fish as you always do.
What if I catch a fish I cannot identify?
Leave it out of your report, or take a photo and email it to the project coordinator with details about where you caught it and what it looked like. Most projects have a process for handling uncertain identifications. Do not guess — bad data is worse than no data.
Can I participate if I only fish occasionally?
Yes. Projects value data from any angler, whether you fish once a month or every day. Even a few reports from your favorite spot add to the picture. Some projects ask for a minimum commitment; most do not. Report what you catch when you catch it.
Do I need special equipment to participate?
A thermometer and a ruler or measuring tape help, but many projects provide these or tell you how to estimate measurements. A smartphone to take photos or fill out a form is useful but not required. Some projects mail equipment to participants; ask when you sign up.
Will the project share my location data publicly?
It depends on the project. Some publish exact GPS coordinates; others generalize to a named spot or a grid square to protect access to good fishing. Read the project's privacy policy before you start, or ask the coordinator how they handle location data. Most projects are careful about this because they know anglers value their spots.
