(DAUPHIN ISLAND, Ala.) — In an effort to improve survival of oyster larvae grown at the Auburn University Shellfish Laboratory, scientists are adopting innovative techniques developed by John Supan of the Louisiana Sea Grant Oyster Research Laboratory. These high-density larval culture techniques will allow for tighter control of production conditions.

This effort to help the new off-bottom oyster farming industry in the northern Gulf of Mexico is being funded by the Gulf States Marine Fisheries Commission with support from the Mississippi-Alabama Sea Grant Consortium and Louisiana Sea Grant.

Currently, Auburn University Shellfish Laboratory is one of only a handful of hatcheries producing oyster larvae and seed in the Gulf of Mexico. It is the primary provider of seed for the off-bottom oyster aquaculture industry in Alabama. In addition, it provides seed and eyed larvae to growers and researchers in the region. In 2014, for example, the shellfish lab produced over 188 million eyed larvae and over 12 million oyster seed. Read more
