Jellyfish for world hunger

[MonDie]

I recently watched a YouTube video documentary called "Jellyfish Invading Japan".  Jellyfish thrive in dead zones that result from pollution, over-fishing, or climate change, and the jellyfish out-compete the natural fish populations.  However, a chef discovered ways to cook the toxic nomura jellyfish.  I wonder whether our jellyfish problem might solve world hunger.
