Fishes in Guatemala - Last Update from the field

FMNH Fishes recently returned from our collecting expedition to Guatemala.  Here are a few final photos from the trip.  We will update again soon as we unpack our specimens and work to incorporate them into the Fish Collection at The Field Museum! susancaleb_tissue.jpg Susan and Caleb work on taking tissue samples from specimens after collecting at a site.

Fishes in Guatemala - Peten II

After making our way to El Remate, along the shore of Lago Peten-Itza, we settled and prepared to start our sampling of the region.   We started the morning by collecting from the shore of the lake with cast nets and seines.  We collected several cichlid species that were targets for some ichthyologists in the group, such as Thorichthys affinis, ‘Cichlasoma’ urophthalmum, Petenia splendida, and Paraneetroplus melanurus.

Fishes in Guatemala: Las Verapaces

After a couple of days filled with sorting out logistics, and driving away from Guatemala City, we have sampled at our first localities (Las Verapaces - Baja Verapaz and Alta Verapaz Departments). Our localities so far have centered around the Rio Escondido and Rio Cahabon, both north of Guatemala City. We found livebearing fishes of the family Poeciliidae (e.g. Pseudoxiphophorous spp., Poecilia mexicana), as well as cichlids, tetras, and catfish.

Fishes goes to Guatemala - Follow us in the field!

Next week our staff in Fishes at The Field Museum will be leaving the cold, snowy days of Chicago to study neotropical fishes in the Central American country of Guatemala!  The Field Museum has always been an important institution for studying the biodiversity of fishes in the tropical rainforests of Mexico, Central America, and South America.  On this expedition our Fishes staff will continue to build on our fish collections from the region so that we can answer even more questions.
