Two weeks ago the Cape Eleuthera Institute (CEI) harvested over one hundred black penshells from a beautiful beach at Ten Bay, located near Palmetto Point. Penshells are a kind of scallop, and we aim to culture them here at CEI for a of couple reasons. As filter feeders, penshells thrive in water with higher nutrients, using the nutrients to grow and as a result clean the surrounding water. Currently, we have our collected penshells in two separate groups: one group in the wet lab in a flow through tank, and another group in a small cage about 100m off the beach where our main pump intake is. In the lab, we feed the penshells concentrated microalgae, whereas the group out in the ocean does not get fed. We are monitoring both groups daily, by recording temperature, dissolved oxygen and salinity.

Once both groups are acclimated and showing good growth rates, we are going to attempt to breed them and raise penshells into maturity. We plan on putting the resulting stock in the mangrove Continue reading →
