Hi. Let's do some math. TL;DR at end
From the Clay Minion Wiki Page (https://hypixel-skyblock.fandom.com/wiki/Clay_Minion), we can see that a t11 Clay Minion does 1.88 harvests per minute, meaning that in a 24-hour day (1,440 minutes), one minion does 1.88 * 1440 = 2,707.2 harvests per day. Each harvest yields 4 clay, so you are producing 10,828.8 clay per day. For convenience, we will round down to 10,828 clay per day.
You should always have a Super Compactor 3000 on your clay minions, so we will include that in the calculations. Because Enchanted Clay and regular Clay give the same amount of experience per clay (0.1 per clay, 16 per enchanted clay), the fishing experience yield PER MINION is simply 10,828 * 0.1 = 1,082.8 fishing experience per day. For ten minions, we multiply by ten, giving 1,082.8 * 10 = 10,828 fishing experience per day for your setup, with an additional 324,000 coin NPC money profit per day also.
TL;DR: 10 T11 Clay Minions produce 10,828 fishing experience per day, and 324,000 coin profit per day if you sell to NPC.
