Every oyster that humanity has consumed started as a miniscule larva, invisible to the naked eye. During these stages, the larvae are most sensitive and reliant on the lipids they receive from phytoplankton. In fact, over 30% of the larvae die before they reach adulthood. We hypothesize that our novel phytoplankton blend using optimized algal sizes will result in higher survival and settlement rates of oyster larvae compared to the industry-standard algal concentrate.
