Sarasota Environmental Aquatics Team - Seagrass Survey Program

The Sarasota Environmental Aquatics (SEA) Team is a group of Sarasota County volunteers whose work has made positive impacts on our bays. Whether they are seeding scallops or surveying seagrass, this team of energetic volunteers provides scientists with valuable information.Seagrass survey volunteers boat or kayak Sarasota’s bays and document the types of seagrass they see. Seagrass is vital to maintaining healthy aquatic ecosystems, stabilizing shorelines and providing food and shelter for a variety of wildlife, including scallops, manatees and sea turtles. The information gathered by seagrass survey volunteers allows scientists to better understand and manage these important ecosystems. Many volunteers find surveying seagrass fun, easy and rewarding.

Requirements: Attend a two-hour training session and be available a few days during the months of February or August. Note: Volunteers should have their own GPS, boat or kayak, but when possible, those who do not will be paired with those who do.

Biologists ask public to report spawning horseshoe crabs

This spring, biologists with the Florida Fish and Wildlife Conservation Commission’s (FWC) Fish and Wildlife Research Institute need help from the public to identify horseshoe crab spawning beaches throughout the state.

The best time to find spawning horseshoe crabs is around high tide, just before, during or after a full moon. The full moon conditions around March 30 and April 28 will create good conditions for viewing the spawning behavior of horseshoe crabs.

The FWC asks beachgoers to report the number of horseshoe crabs they see and whether the horseshoe crabs are mating. Mating crabs “pair up,” with the smaller male on top of the larger female. Other male crabs may be present around the couple. Biologists also want to know the date, time, location, habitat type and environmental conditions, such as tides and moon phase. If possible, specify roughly how many are coupled and how many are juveniles (4 inches wide or smaller).

Citizens can report sightings through one of several convenient options. Go to http://research.MyFWC.com/horseshoe_crab and fill out an online survey; e-mail findings to horseshoe@MyFWC.com; or call the FWC at 866-252-9326.

Fossil records indicate horseshoe crabs first appeared 450 million years ago and have remained virtually unchanged since. The species is an important part of marine ecosystems; their eggs are a vital food source for animals and birds, such as the red knot.

Horseshoe crabs are important to humans as well. For instance, in the biomedical industry, horseshoe crab blood helps save human lives. Pharmaceutical companies use horseshoe crab blood to ensure intravenous drugs and vaccine injections are bacteria-free. Scientists have found that no other test is quite as reliable as horseshoe crab blood, which clots in the presence of infectious bacteria.  Also, research into horseshoe crab eyes has given scientists a greater knowledge of the functioning of human eyes.
