Video-endemic fish species in Laguna de Apoyo





Six fish species are known to inhabit only Laguna de Apoyo. Our research group at FUNDECI/GAIA in collaboration with scientists from US and Europe discovered five of those six, and we have a few other taxa targeted for species recognition from this lake. We are conducting a long-term fish population monitoring project in Lake Apoyo, in part to provide information about the populations of each species in order to assure their continued existence. We gather this date while SCUBA diving. See the film of one of those dives, below.

Volunteer divers participate in monthly monitoring of fish transects in Laguna de Apoyo.

The fish species found in Lake Apoyo are:

Amphilophus astorquii^
Amphilophus chancho^
Amphilophus flaveolus^
Amphilophus globosus^
Amphilophus supercilius^
Amphilophus zaliosus^
Parachromis managuensis
Poecilia sphenops
Atherinella sardina
Gobiomorus dormitor*
Oreochromis aureus*
Oreochromis niloticus*
^-endemic to Laguna de Apoyo
*-recently introduced by human activity
The volunteers and staff at Estacion Biologica FUNDECI/GAIA are conducting long-term fish population monitoring in a program that encourages "citizen participation". Certified divers can join us in the dives and help us collect data. 

Our work has led to more than a dozen scientific publications on the fishes of Laguna de Apoyo, and five species of fish have been discovered by our staff in this lake. Furthermore, one of these species, the arrow cichlid (Amphilophus zaliosus), has recently been listed as Critically Endangered on the IUCN Red List.
Would you like to help us monitor and protect the endangered fishes of Lake Apoyo? Certified Open Water divers are welcome to join us in this vital work to protect the natural heritage of this beautiful lake. Please contact us for more details.
