Exploring Laguna Grande, the bio bay in Fajardo
Bioluminescent Bay Laguna Grande in Las Croabas is a one of a kind ecosystem situated along Puerto Rico’s northeastern city of Fajardo. It is the second best-kept bioluminescent bay in Puerto Rico after Mosquito Bay. Visiting a bio bay is by far the most mystifying experience of the island.
Laguna Grande, also called “The big Lagoon” was first spotted by the Spanish in the seventeenth century when they stumbled upon the “devil” glowing water reservoir. They made an effort to prevent the water from the lagoon from entering the ocean. Luckily, by shrinking the outflow from the bay, they aided in luminescence increase.
The uniqueness of bio bay waters consists of its oceanic residents which can light up in the dark. Bioluminescence is genuinely a special occurrence of fragile nature’s ecosystem. The luminescence happens all over the earth, yet only a handful of places are categorized as bio bays. Most of them are at high risk of vanishing because of extensive urban intervention and deficiency of ecological regulations. Fortunately, the bioluminescent bay in Fajardo, Puerto Rico is in good shape featuring great night scenery. Go and check it yourself with a bio bay tour
There are many strict requirements essential for the eco-community of luminescent microorganisms, named dinoflagellates, to remain alive and active. The mangrove trees surrounding bio bay supply various nutrients and minerals from roots and decomposed foliage. A narrow-sized canal connecting Laguna Grande bio bay with the ocean influences the microclimate and temperature within the lagoon. Any transformations of the canal causing it to be deeper, shallower, wider, etc may destroy a bioluminescent bay.
One more pernicious factor for Fajardo lagoon’s vitality is city-wide development linked to increasing levels of air, soil, and water pollution. Year 2015, in an attempt to keep the vulnerable bio bay active and alive, the DNER (Department of Natural and Environmental Resources) of Puerto Rico prohibited swimming in the bioluminescent bay. Since then, there is also a daily limit on the total number of people that could paddle into the bay.
