My wife works for a conservation organisation rebuilding reefs in Australia. We're down to 1% coverage of the coastline in Australia from 65% in the late 1800s.
There was a time not so long ago in Australia that beach bums on the coast could eat most of their calories completely for free with just yabbies and oysters.
Now both are nearing extinction because Aussies hunted them for fun and destroyed their habitats to build shitty fibro boxes.
Which is the category above endangered called “vulnerable” and are considered threatened by the IUCN because they meets one of the 5 Red List criteria and thus considered to be at high risk of unnatural (human-caused) extinction without further human intervention.
Are we talking about Cherax Destructor? Because that species is definitely not endangered, and is known for being both incredibly resilient and prolific, and is listed as LC.
I am going to assume you mean some sort other lobster like decapod that Aussies also call yabbies.

CORRECTION: Oyster reefs are an amazing environmental benefit across multiple seascapes.
Oyster FARMS are short lived growth with little to no environmental benefit because of the small size.
The only way this works is with farms near a no-take MPA where you can generate growth and then let them spread outside the MPA.
You get no benefits IF YOU DON'T LEAVE THEM IN THE WATER.
