So far,
Tank raised fish are to the industry what backyard tomato growing is to feeding the nation.
Growing what is easiest...ie fish w/ large eggs and larvae is a far cry from growing what the trade would actually need to make any difference...ie culturing commercial quantities of tangs, butterflies, angels, wrasses, damsels, groupers, bats, anglers,triggers etc.
Then again is the elite pro-laboratory sector vs. the poor fisherman quandry.
Fisherman will do something with the sea. At least w/ tropicals we have a say and an input into it to moderate catch methods.
All cultured livestock [ a myth and impossibility in any readers lifetime ] will simply divert the fisherman into food fishing and probably greater impact on the reefs we say we wish to "save."
Funny way to pretend to save anything.
Cultured stuff is a placebo at best and a cheap deodorant in lieu of a shower.
It is something...but a foundation of the industry it is not.
Unlocking the secrets of micro-larval care and rearing have kept progress at a glacial pace and will not come in time to save anything.
The industry is clearly sustained by wildcaught livestock while cultured fishes progress far slower then reef destruction.
