FishAmerica Foundation works with ACFHP and FWC to Fund Sponge Restoration Project in Florida Bay

May 7, 2020

The FishAmerica Foundation recently awarded the Florida Fish and Wildlife Conservation Commission (FWC), through the Fish and Wildlife Foundation of Florida and Atlantic Coastal Fish Habitat Partnership (ACFHP), funding to increase fish habitat in Florida Bay. In recent decades, recurring algal blooms have affected large portions of the shallow waters of the Florida Keys. These blooms suck the oxygen out of the water, causing extensive sponge die-offs and turning once healthy areas into “sponge barrens” that no longer provide habitat for recreationally and economically important fin- and shellfishes such as gray snapper and spiny lobster.

In response to this loss, FWC will plant 5,000 sponges in degraded sites, and will monitor the use of restoration sites by mobile fauna. To date, several thousand sponges have already been propagated within a network of in-water sponge nurseries in the Florida Keys with great success. When transplanted onto sponge-barren seafloor, sponges produced by this method exhibit high growth and survival, and provide habitat for many fishes and invertebrates.

Recently fragmented yellow sponges, Spongia barbara, in one of FWC’s in-water sponge nurseries. After a few weeks, the sponges adhere to the limestone substrate on which they are attached, and the plastic cable ties can be removed.
