Lake Malawi Red Zebra Tours
They show you the process in which the divers gather the fish and and take them to the fishery to be shipped across seas. From what I understood from speaking to another collector, you can inquire on prices to keep fish they catch or pay a few to go diving yourself and do your own gathering. I haven't spoken to anyone about it further than that yet as it's going to be years before I plan or can do anything of the sort.
