Helping Queen Conchs Mate In The Florida Keys

In shallow water not far from the Florida Keys’ famed Seven Mile Bridge, a herd of the state’s flamboyantly pink queen conchs is struggling to survive.

Warming seas and wild swings in temperature have shut down their reproductive impulses in the waist-deep water, leaving them to creep along the ocean floor, searching for food but not love. Meanwhile, just a few miles away in deeper, cooler waters, the iconic mollusks mate freely. So scientists have a rescue plan: load the inshore conchs into milk crates, ferry them to colonies in deep water, and let nature run its course.

As climate change fastracks ocean warming, the researchers hope their plan hatches enough baby conchs to help boost the flagging population.

“Once you put them in a more appropriate temperature regime, snails have a remarkable capability to heal themselves,” says Dr. Gabriel Delgado, a conch scientist with the Florida Fish and Wildlife Conservation Commission who is leading the pilot project. “Now you have a contributing member to future populations.”
