You are currently hands on with shellfish, that's a good start.
I'm not a degree biologist either, insomuch as an erudite having knowledge that is known by very few people. Most of the papers I've read had little or nothing to do with pearl culture, insomuch as how shells are formed. I started with
Invertebrate Zoology by Robert Barnes, after all, there was no internet when I began working with pearls. At the very least, learned the terminologies so I could get directly to the point of my questions with others. A clam is a clam is a clam, irrespective of it's hemisphere of origin. While there may notable differences, the general processes are the same.
The first pearls were cultured in China during the Song Dynasty (960-1279 AD). Carl Linnaeus, a Swedish biologist and physician formalized
binomial nomenclature, the system of naming organisms aka modern taxonomy. He grew pearls using shell beads attached to silver wires. Both methods similar to extrapallial "mabe" pearls in modern aquaculture.
It was William Saville-Kent who pioneered the homogeneic epithelial trans-graft as we know it today while he was Commissioner of Fisheries for Western Australia. During this time he experimented with culturing pearls on
Thursday Island. His experiments were successful and modern-day spherical cultured pearls are primarily the result of discoveries he made. These discoveries were later co-opted and patented by Dr.
Tokichi Nishikawa and Tatsuhei Mise of Japan. To this day the Nishikawa/Mise method is used by most saltwater pearl farms in their operations.
I began grafting pearls in Canada in 1986, using a non-bead nuclear variation of the method. At the same time, 20 miles south of my farm at Lagoon Island in Grappler Cove, near Bamfield, Dr. Peter Fankboner induced pearls in abalone using a process patented as the "American Method".
Pearls as gemstones was a hard nut to crack, given the level of competition from Japan, South Sea and Oceania pearls, then later China. Instead, shifted to bio-medical research, environmental/climate studies and public health and safety practices.
I'm retired, but still go pearling from time to time. I run claims and crews on other gemstone mining operations in BC and contribute to molluscan fossil pearl research for the Royal Tyrell Museum in Drumheller, AB. Needless to say I have my hands full, so to come out of or offset retirement any project would have to be lucrative enough to do so. That's not to suggest I'm not approachable, but merely not dependable on demand.
If you're serious in your intentions, start with that. Cross the grafting bridge when you get there. When you get to that point, I can help you.

here. It's free and will help you with a lot of the identification and market aspects of pearl culture.
