It seems strange to mark the location of a fish, doesn’t it? They can swim and move away from the marker, right? I wonder while standing on a dock waiting for the boat that will take about ten of us out to a reef. There, we will scuba dive for fun and also mark the locations of lionfish, an invasive species in the Caribbean.
Volunteer divers on the Dutch island of Bonaire are helping Bonaire National Marine Park eliminate invasive lionfish from its coral reefs by marking the locations where the fish are found. A diver who spots a lionfish is instructed to attach a small flag, provided by the park, to a rock near the fish.

The answers to my questions about marking fish locations become clear once I splash into the water and see the fish and flag markers for myself. Swimming along sections of reef, I saw dozens of flags that had been placed there by divers and each had one or more lionfish hovering nearby. It turns out that lionfish don’t stray far from their particular nook of reef. They stay near the markers.

It’s illegal to hunt or in any way harm marine life in the waters surrounding Bonaire. Except, that is, for lionfish.

They are beautiful fish, placidly fluttering their glitzy ruffle of fins, and hovering next to their flags. Yet, a voracious appetite for reef fish combined with a high rate of reproduction and no known predators in the Caribbean make lionfish a threat to biodiversity. Native to the Pacific, the lionfish is an invasive species in the Caribbean.

On Tuesday, July 26 at 9pm ET, The Weather Channel will air the “Changing Planet” Town Hall focused on clean energy and green jobs. Science for Citizens is a partner in this three-part series. Here’s more information from NBC News: This town hall broadcast is the second in a 3-part series that brings together scientists, […]

Changing Currents, a project originating in Toronto, Canada, familiarizes middle- and high-school students with local watersheds and teaches them how to conduct water quality analyses. This is a great way for students to become environmental scientists for a day! After heading out to a local stream and donning hip waders, students collect water samples and analyze […]

Citizen science is taking off in Puerto Rico! According to a story at Ciencia PR, citizen scientists are playing an important role in the conservation efforts for the Hacienca La Esperanza Reserve, which houses the only coastal forest in Northern Puerto Rico. Through the Puerto Rico Conservation Trust’s Citizen Science Program, volunteers have the opportunity to explore and observe the […]

In July of 2009, a friend and I arrived at a lake to collect water samples for work. We had worked at the lake many times, but something was different that day: several hundred dragonflies were flying over the grass. We often saw dragonflies, but there were 50 times the usual number and they weren’t […]

Da-dum … da-dum … Don’t look now, but there are  researchers hoping you’ll hop in shark-infested waters in the name of science! Members of ECOCEAN want your help photographing whale sharks on your next ocean outing. Your pictures will be uploaded to the ECOCEAN Whale Shark Photo-identification Library, a photographic database of whale shark (Rhincodon […]

Participating in PhillyTreeMap, one of the newest projects in the Science for Citizens Project Finder, is almost as simple as fetching the morning paper from the front “stoop,” as we say here in Philly. This morning, I opened my front door, walked 10 feet to the nearest tree (pictured here), wrapped a measuring tape around its […]

Some of you may have fond memories of summers spent kneeling by nearby streams, peering intently for crayfish to play with (or cook up for dinner!). These tiny, lobster-like creatures are a staple of freshwater ecosystems, southern menus, and even neuroscience classes. (No kidding — I learned about action potentials from a wonderful college professor […]

Next week is National Pollinator Week! Pollinators, like bees, birds, and butterflies, play an important role in all of our lives. They aid in flowering plant reproduction, help ensure the health of national forests and grasslands, and work together with famers and ranchers in the production of fruits and vegetables. National Pollinator Week is a yearly […]

I love being in the outdoors amongst nature – but then who doesn’t? I also have a fascination for all things technological. Sadly, all too often these two passions are incompatible. For as us techie-lovers know, too many an hour can be spent cooped up inside staring at a computer screen. The emergence of the […]
