Citizen Science

Loricariids are incredibly popular in the aquarium fish hobby, as is attested to by the nearly 200 aquarists from across Europe who attended the Fourth International L-Number Days event in Hannover, Germany, in November 2015 (top). As a speaker at this and similar events in the US and UK, I have met many aquarists and been impressed by their dedication to the captive husbandry and reproduction of a wide range of often rare, 

undescribed or otherwise poorly studied loricariid species. Both aquarists and businesses that cater to this hobby go to great lengths to recreate natural habitats, as is obvious in the display tanks of Panta Rhei (right), a store and equipment company on the outskirts of Hannover. After learning about my research via talks and articles that I write for aquarist magazines (e.g., these on Andean and Guiana Shield fish diversity), many aquarists have voiced an interest in participating in my research by sending tissues from wild-caught animals in their care. At this point, I am primarily incorporating these tissues into my phylogenetic studies of loricariid evolution, but I anticipate a future time in which a combination of population genomics and captive husbandry by aquarists will be essential to the conservation of species that are threatened or endangered in the wild.

Opportunities to Participate

With over 950 valid species in the Loricariidae, acquiring enough 

specimens and tissues to gain a comprehensive understanding of this family's evolution is incredibly challenging. In addition to my own field work, I borrow specimens from a wide range of other researchers and am beginning to benefit from the contributions of aquarists. If you have a species in your care that I do not already have in my sample set (see list below), then you can help by mailing me a fin clip along with high quality photos of your fish. One species that I am particularly interested in having aquarist fin clips of is Hypancistrus zebra. This species is threatened in the wild and may need captive propagation to escape extinction.

Things to Keep in Mind

If you are interested in participating, please keep in mind that this is a scientific undertaking in which care must be given to ensure that accurate information is recorded and unambiguously linked to each specimen. I recommend that participants start by setting up a database in which they record the names of their species, any information that is known about the original locality from which the fish were collected and exported, and a unique alphanumeric code (e.g., your initials plus a sequential number) that can be used to link the tissues, photos and data. I am most interested in species and/or localities that I do not currently have representatives of, so please check the list of species that I currently have

(below) before moving forward.

How to Participate

Please start by emailing me, introducing yourself, and attaching a copy of your specimen database. In order to confirm the identification of your species, I will also need relatively high resolution, high quality images of each fish in lateral, dorsal, and ventral views. Good photos of the mouth are also helpful. To preserve the DNA of your fin clips, you will need to place them in 95% ethanol (i.e., drinking alcohol, neither methanol nor isopropanol will suffice), inside a small tube or vial that can be sealed tightly. It is very important to also label this tube with the unique alphanumeric code from the database. The tube should be labeled both internally and externally with pencil, since leaking ethanol will erase the ink from most pens.
