Indian River Lagoon Clam Restoration to Help Restore Important Waterway

Outplanting clams in the Indian River Lagoon

Whitney Laboratory along with partners are working to restore clam populations in the Indian River Lagoon. Your support of this project will help bring clams to the IRL with the goal of improving water quality and restoring healthy seagrasses to this important estuary in need of our help.

The Whitney Laboratory secured $2.2 million in funding for clam restoration in 2022 from the Florida Fish and Wildlife Commission (FWC) and Indian River Lagoon (IRL) National Estuaries Program to restore super clams to the IRL until summer of 2025.

Dr. Todd Osborne and his lab are working with project partner Premium Seafood (Mike Sullivan) to produce the 15 million clams needed for this restoration project. These efforts employ five staff members in the Osborne Lab and is a tremendous undertaking that now involves two additional Ph.D. students. These students study the processes of population enhancement and ecosystem services provided by growing clam populations in the IRL.

Seagrass restoration has been coupled with this project so that “co-restoration” efforts can hasten ecosystem recovery. Project partner Dr. Lorae Simpson (Whitney Lab alumni) serves as the Research Director for Florida Oceanographic Society, which houses a seagrass nursery in Stuart, Florida. Dr. Conor MacDonnell, a post-doc in the Osborne Lab is stationed onsite there, bridging the programs and conducting research on clam and seagrass interactions.

2022

The Whitney Laboratory secured $2.2 million in funding for clam restoration in 2022 from the Florida Fish and Wildlife Commission (FWC) and Indian River Lagoon (IRL) National Estuaries Program to restore super clams to the IRL over the next 24 months. Dr. Todd Osborne and his lab are working with project partner Premium Seafood (Mike Sullivan) to produce the 15 million clams needed for this restoration project. These efforts employ five staff members in the Osborne Lab and is a tremendous undertaking that now involves two additional Ph.D. students. These students study the processes of population enhancement and ecosystem services provided by growing clam populations in the IRL.

- 40 million larvae were released into the Matanzas River in 2022 with support from the South Anastasia Communities Association (SACA).

- Whitney Laboratory joined with Star Brite Solutions, Coastal Conservation Association Florida, and the IRL Clam Restoration Project to plant 100,000 clams, along with dozens of red mangroves, in the Indian River Lagoon on Earth Day.


2021 

The Indian River Lagoon Clam Restoration initiative entered its third year in 2021. In 2019, adult Mercenaria mercenaria clams were collected from Mosquito Lagoon and spawned. These “superclams” survived the brown tide and hypoxic event of 2012 and subsequent bloom events prompting Dr. Todd Osborne to believe these clams are genetically stronger and would produce progeny capable of survival in the Indian River Lagoon (IRL).

A total of 2.5 million clams were raised and repatriated to aquaculture lease locations in the IRL in the first year. During the pandemic, the project was able to maintain productivity with the strong collaborations between Blair Wiggins Outdoors, Premium Seafood Inc, St. Johns River Water Management District, Florida Fish and Wildlife Conservation Commission, The Coastal Conservation Association, Star Brite and the IRL Council. Project partners and Whitney researchers distributed more than 11 million clams at the close of 2021. Dr. Todd Osborne and Mr. Jose Nunez have secured funding from the IRL Council, FL DEP and private donor sources for 14 Mil additional clams from 2022-2024.

A significant portion of our current work is in collaboration with the Brevard Zoo in developing a new clam gardener program that has established 100 clam grow out sites within Brevard County that are being monitored by citizen scientists. This program will mirror the oyster gardener program in its punctuality and will allow Whitney researchers to gather spatially explicit information about clam populations in the IRL. Monitoring of water quality and natural recruitment will continue for the duration of this project.


2020 

The Indian River Lagoon Clam Restoration initiative entered its second year in 2020. In 2019, clams were collected from Mosquito Lagoon and spawned. A total of 2.5 million clams were raised and repatriated to aquaculture lease locations in the Indian River Lagoon. During the pandemic, the project was able to maintain productivity with the strong collaborations between the SJRMD, The Florida Fish and Wildlife Commission, The Coastal Conservation Association, Addictive Fishing Television, Premium Seafood Inc. and the IRL Council.

Project partners assisted Whitney researchers in distributing an additional 1.6 million clams with a target of 6.4 million more clams planted by the end of 2021. Dr. Todd Osborne and Mr. Jose Nunez have secured funding from the IRL Council, FL DEP and private donor sources. A significant portion of future work is in collaboration with the Brevard Zoo in developing a new clam gardener program that will establish 100 clam grow out sites within Brevard County that will be monitored by citizen scientists. This program will mirror the oyster gardener program in its punctuality and will allow Whitney researchers to gather spatially explicit information about clam populations in the IRL. Monitoring of water quality and natural recruitment will continue for the duration of this project.


2019

Adult Mercenaria mercenaria clams (6-8 years old) were collected from Mosquito Lagoon in March 2019. These “superclams” survived the brown tide and hypoxic event of 2012 and subsequent bloom events. At the Whitney Laboratory bivalve hatchery, these clams were spawned and then raised in land-based and field-based nurseries. After approximately nine months, nursery-raised clams were repatriated to selected aquaculture lease locations in the Mosquito Lagoon and in the Indian River Lagoon (IRL) proper.

Of the 3-4 million clams that were reared during the first year of the project in 2019, 400,000 were moved to Mosquito Lagoon in December of 2019 and the rest will be out-planted to additional sites throughout the IRL by the spring of 2020. By then, the clams will be one year old and will be ready to begin spawning in the wild, jump starting their natural recruitment in this important estuary. Monitoring of water quality and natural recruitment will continue throughout the duration of this project.
