Beta Tottoro IV
Beta Tottoro IV was the inhabited fourth planet in its star system. The inhabitants of this world had maintained kelp farms for decades. Sometime, in the past, the farmers had used saltzgadum, but this practice was discontinued due to cost. 

This planet was mentioned in a list of five substances that had the potential to cause disruptions in the systems aboard a Federation starship. (, okudagram)
