False equivalence.

Shellfish industry is both massive and more importantly long running with health and safety checks throughout its history.

There is no mass production of insects yet despite all the talks about it and even if there were the examples used in that image are not what anyone should use.

• The scorpion, which isnt even an insect, is evidently a highly venemous species and not suitable for worker handling, the Indian forest scorpion would be a far more suitable option.

• The Bladditae, aka the cockroach, is far too chitinous for any suitable meat yield meaning significant energy costs are wasted per individual.

• The Orthoptera, while being one of the few insects in the Bible permitted for consumption as mentioned in Leviticus, is too small a species for any significant meat yield, likely yet another example of whomever made this "meme" just grabbing random arthropod pics without any actual background info in the specific examples.

On top of all that, tropomyosin allergies mean anyone allergic to eating the top examples will also be allergic to eating the bottom examples.
