In Animal Crossing New Horizons, Fishing Tournaments are special events that let the player try to catch as many fish as they can in a limited time to earn points – that can then be exchanged for limited time fishing-theme swag.
As you accumulate points for each fishing attempt you undertake, you can exchange 10 points with C.J. to get a random fishing-themed item. He will also keep track of your point total for the day, and award you a trophy if you’ve amassed enough points over the course of the Fishing Tournament day:
|100 Points Total||Bronze Trophy|
|200 Points Total||Silver Trophy|
|300 Points Total||Gold Trophy|
Given the rate at which you are likely to accumulate points (and knowing that everyone will catch fish at a different rate depending on skill), you can likely expect to take up to an hour accumulating 100 or so points.
Below are all the different prizes you can win from the Fishing Tournament by trading in 10 points to C.J.. He should give you a different prize each time you trade in points until you have each type, at which point you will then start receiving duplicate prizes.
