You can find journals for keeping track of the fishing online. You can modify them to keep track of anything you want. Handy to have. I documented over 30 years of crappie fishing on a local lake, all hand written entries on printed sheets I’d made up and now being written onto a dvd I can pop into the computer to go back and see how things compare.
I think there are programs similar to blank spread sheets that would work off the computer too but that’s above my pay grade. You could create areas to enter any data that fancied you. I did start and stop time, barometer at the start and barometer oat the stop, atmospheric conditions [cloudy, partial cloudy, etc], temp at star, temp at stop, water temp at start and at stop, type of crappie[white, black], bait’s description, depth caught, time caught, water clarity and sex of the fish if during the spawn, and length of each fish. You can make this journaling as complex as you want, however I suggest writing this data out in long-hand and then re-entering it to whatever format you chose later. By physically writing this information out you have a better chance of retaining little details that might be missed later.
And expanded that journaling eventually to if I kept fish to eat I’d get a scale sample to age later on too along with the weight and length of the fish providing the scale sample. Each sample would be assigned a number so I’d be able to keep track of that info separately. One might be amazed at growth rates and how each year can affect the size of the crappies.
Its a fun hobby to have if you want to take the time to record the information and it doesn’t take very long to see things come together that you never knew before.
