How would you make this app?

[Bishop]

Hello all. I am looking for some recommendations. I work for a fishing lodge, and we need a quick and efficient way to copy down this board of fish records for each guest trip that flys in.

There are 18 trips with roughly 35 guests each
Each trip is either 3 or 4 days long
The app has to track all 3 or 4 days of the trip in a clean looking way

Does anyone have any suggestions on what route to take for views and layout?

I want the trips to almost be the category, then you go in and can add fish to day 1, 2, 3, etc.

Thanks for your help.
