Assisted by L. Christine Savolainen in breakdown, photography, processing, and rebuild of trays.
Sampling followed a protocol similar to that of Fidalgo Bay. We broke down the trays and evenly spaced them out. I cleaned the trays, christine photographed the trays then counted conspecifics and removed them. I collected the dead oysters and organized the trays. Christine then counted the living oysters in each tray. Finally I collected 8 Living oysters per tray and we rebuilt the hanging devices.
Field Notes as written:
Hatchery owner/biologist mentioned argonite index dropping below 1.5. Oyster shells very delicate. Heavy Sponge Growth on ALL trays.
Trays had many sea stars, urchins, seaweed, mussels, chitins, and anemones associated with them. Luckily no sea stars or urchins were within the trays. The tables below give the live counts for each tray as well as full counts for conspecifics in each tray. Most mortalities found were caused by oyster drills as almost all the shells had the characteristic drill mark on them. Also an orange sponge was found overgrowing the bottoms of nearly every tray and on several of the oysters. It cemented the oysters to the tray which was broken off while counting live animals.
