We need your help to learn how fishing is changing along our coast.  It is no surprise to anyone who regularly spends time fishing in coastal Louisiana that wetlands are disappearing, and our coast is constantly changing. This ever-changing environment has consequences for the variety of fish and wildlife that depend on our estuaries; this includes where fish are located, the amount of time and effort that it takes to catch them, and numerous other factors.  


CRCL has developed an app to help us understand the effort that goes into fishing and where various species are being caught. The app also allows each user to create a private journal of their fishing trips that provide environmental data (wind, temperature, salinity, etc.) linked to the location where they catch fish. The small amount of time it takes you to use the Fish for Data App helps us greatly understand changes in fish populations and provides a tool to help users understand how environmental conditions are related to their catch.  


Steps for Anglers using the App:



Download the App by searching for “CRCL- Fish for Data” at the Apple App Store or Google Play Store (or for android click here).



Go on your usual fishing trip and make sure your phone’s location services are turned on. See questions 4-6.



Once you make a catch, open the Fish for Data App and take a picture of the catch by clicking on “capture”.

  • Capture a picture of your catch and enter the data after fishing at each spot.   This way, the App will provide you with a personal record of the environmental conditions associated with each catch.

  • Or you may take the picture as you normally would and upload it in the app later. Be sure to note the type of fish, size, quantity, and time spent fishing so you can input that info later as well. Regardless, make sure you take the picture at the spot you catch so the location data is accurate.

  • You can use this App as a private online journal to look back on your fishing trips and records of the coordinates and data. We do not share any personal information. Everything is anonymous, and no information will be used for fishing purposes.

  • Name each “capture” or “upload” with a description of location and/or catch. For example, “redfish at old bridge” or “Specks in Barataria”.

  • The App sources real-time data based off proximity to data collection stations and sites. This means that some data may not be instantly available, but you can go back to the catch in the App later and select “refresh” and it will check for any new data that is available.


  • If you are fishing in an area with limited or no cell service, you may not be able to save photos directly through the App. GPS service works regardless of cell service so just take a normal picture and upload it and the catch info into the App later.


  • You can upload past pictures into the app as well! If you have pictures in your phone that were taken months or even years ago while you were out fishing, you can also upload those and receive the environmental data (as long as you had location services turned on).

  • If you are experiencing a lack of tide data on the App, it is most likely because there are no nearby tide stations or buoys for your current location. See a map with the locations of all the NOAA tide stations Click here.
