Interesting! I wonder if it should give us pause that we're continuing to try to farm a creature that's so far proven too smart to allow us farm it successfully...
I believe the problem is that the octopuses (or cuttlefish, same problem) slowly produce less and less fertile percentage of eggs. So, first year 100%, then 50%, 20%, 5% then all sterile after five years, that sort of thing. And so far nobody really understands what we are or aren't doing, or what special nutrient, mineral, bacteria, plankton, something is or isn't present in the environment...
