Ok, you did specifically mention the "Hawaiian divers" so yeah I focused on half of the two groups you mentioned. As for the wholesalers (you didn't mention the shippers in your original post) why do you assume they're an independent company only involved in Hawaiian collected fish instead of part of a bigger company? And even if they did completely have to close down the company, again, this is Hawaii we're talking about...I highly doubt they were jobless this entire time.
Btw, do you not think they're highly trained professional divers? Does it not make sense they could find work in a major location where many tourists dive?
