I'm sorry, I based the description from my preliminary testing and the information available on the mod portal page, mainly focusing on the planetary unlocks, as opposed to the actual gameplay that would take place on the planet. I try to keep the descriptions short, so a lot of contextual information may have been omitted, or worded poorly.
... water-based planet that relies on ... Canal Excavators to generate infinite stone (using spoilage from the infinite fish pulled out from the ocean).
Presumably, this would be the line you are referring to? This wasn't meant to be a description of how the planet operates, but a (short) description of how Canal Excavators was being used in the mod (which was taken/modified from its description on the Pelagos mod page).
Since the placeable stone is crafted with spoilage and water, and spoilage can be obtained from various processes (many of which include fish, which can technically be obtained infinitely via breeding, as mentioned on the Pelagos mod page), that is why I wrote it that way, though I can see how it may have been misconstrued.
If you would like to provide a short blurb for me to use as the description, I would be more than happy to add it in.
