Fish Research in Laguna de Masaya

The Masaya volcanic complex, lying just north of Apoyo, also contains a lake full of fish-and very interesting fish! The FUNDECI/GAIA research team are executing a study of the Midas cichlid species complex in Lake Masaya, in search of evidence that sympatric speciation has also occurred in this lake, as has been demonstrated in Lake Apoyo.

Here is Maarten Hogenkamp, fishing in Laguna de Masaya. And take another look at the foreground!!!! Yes, that is trash. This lake is severely damaged by solid waste and liquid waste from the municipalities of Masaya and Masatepe. Nonetheless, the lake has fish, and very interesting ones!

Some of the catch: a probable new species! FUNDECI/GAIA is working with Jay Stauffer from Penn State to describe new species in Lake Masaya.

And yes, fishing also means.... repairing nets, and getting ready for the next round.
