The Iceshanty derby has no size limit

[Bill Dance]

You can enter any size fish in the species your fishing for as long as it challenges 1st, 2nd or 3rd places. If it doesn't then put your fish in the short category.
The trophy sizes that are listed in the rules are the minimum size for entering in the trophy categories.
I hope this clears things up.

I had that noted immediately below the categories in the main tournament post. I just highlighted it in red. Hopefully there's less confusion.

 * Must be at least this length to qualify for randomly drawn Trophy Prize
