Hard Clam Restoration Efforts in the Indian River Lagoon

The video discusses the shellfish restoration initiative at the Whitney Lab, focusing on the Indian River Lagoon (IRL) in Florida. It highlights the environmental challenges faced by the IRL due to coastal development and over-harvesting of clams, leading to algal blooms and seagrass decline. The initiative involves collecting resilient clams, breeding them, and reintroducing them to the lagoon to improve water quality. The video also covers the monitoring of these efforts and future plans to restore the IRL to its historical health.
