All-Aquarium Catfish Convention

All-Aquarium Catfish Convention


Hello dear fish people!

I am here to ask you for an important information. At the 2018 convention, I received donations of preserved Corydoras CW16 specimens. I know Rob donated part of this material but I cannot remember who else donated specimens for me. I would really like to mention the donators in the original description so, manifest here if you were one of my kind donators.

kind regards

I don't see any excursions... no collecting trip on the Rivanna this year?

Hello everyone, how are you? a couple of days ago, Andrew sent me an e-mail asking about my visits to the US museums and collections, what exactly I do in such places and stuff like that. Basically, what exactly the hobby can do for a scientist (or as in my case, trying to be one lol).

To be honest, I love to talk fish. So I said, of course, I can tell you everything but maybe others in the group are also interested so I asked to do it here and not in a private message.

What exactly I do? I do alpha taxonomy. I use morphology/anatomy to (I´m trying to haha) recognize the only natural entity, the 'species'. Every species presents an "equation", a combination of features (rarely a single feature...) that can differ it from all other species (a diagnosis), and my job is to found such equations (a good enough one at least).

Remember my talk at CatCon 2018? the true identity of a taxon (a name, a species) can only be recognized through the comparison between the examined specimen and the 'name holder', the holotype or lectotype.

Very well, in big collections/museums, such as Smithsonian and Drexel, there are generally a huge number of type specimens. However, types are like other specimens, they get old, the color fade... And what I do? first, I do standard measures and counts. After that I check some key features: externally visible bones (infraorbitals for the win), spines (serrations), color pattern,´s very important to take very good pictures of them in three views, dorsal, lateral and ventral (so I have HD images to chech something more superficial later). This way, museum after museum, I´m building a database of Corydoradinae to build more solid diagnosis, provide redescriptions, reviews... =)

I hope this is what you asked Andrew =)

kind regards

Thanks so much for having me, and for putting on such an awesome convention! It was a pleasure meeting everyone!
THANK YOU!!! Everyone!! Safe at home! ;)

Some cool stuff here, if you like the stories behind fish names.


I began working on The ETYFish Project in early 2009, beginning with hagfishes, lampreys, sharks and rays, and moving on up through the “true” or bony fishes. The website and this page went online in October 2013. Yesterday, I uploaded the Family Liparidae, Snailfishes (488 names), the final family in this long ichthyo-etymological trek …

All told, The ETYFish Project provides “complete” etymological coverage and analysis across 601 families, 5222 genera, 330 subgenera, 36108 species, and 514 subspecies. If you were to print all the PDFs, you’d need a lot of paper – 2295 pages.

I still have a backlog of 45 or so new species and taxonomic changes, dating back to May, to work through, so the coverage is not fully “complete” – hence the quotations marks. I will focus on clearing out this backlog over the next few weeks. (But it seems for every new species I add, news of another one appears in my in-box! Danionella cerebrum showed up just a few minutes ago.)

As I tackle the backlog, I am also planning an overhaul of the site, and beginning a revision of all 42,174 entries. That should keep me busy for a few more years. Also, FishBase is interested in incorporating our data into their site. Work on that begins shortly. I will share details when available. For now, enjoy the snailfish names, including that of the lovely Volodichthys solovjevae (shown here).

Thanks for reading. Thanks for the comments and corrections. Thanks for letting me know I am not alone in my fascination for the names of fishes and fish-like craniates.

The Private John Allen National Fish Hatchery has successfully spawned one of the rarest fishes in Mississippi, the piebald madtom catfish, for the second time on station. The first spawning success was in 2019 from wild individuals that were collected and taken on station in 2018. This year, the F1 progeny, produced in captivity during the 2019 spawn, produced an F2 generation. Overall, two clutches had >95% hatch rate and resulted in ~360 juveniles. Majority of the offspring will be held on station and utilized for experimental research studies to gain better knowledge of this unique species and for spawning efforts in 2023-2024. Also, 50 fish were transferred to the Mississippi Museum of Natural Science in Jackson, Mississippi.

Zebra news

New research gives an update on the situation of the critically endangered zebra pleco - L046 (𝐻𝑦𝑝𝑎𝑛𝑐𝑖𝑠𝑡𝑟𝑢𝑠 𝑧𝑒𝑏𝑟𝑎).

Conservation and trade of the endangered 𝐻𝑦𝑝𝑎𝑛𝑐𝑖𝑠𝑡𝑟𝑢𝑠 𝑧𝑒𝑏𝑟𝑎 (Siluriformes, Loricariidae), the most trafficked Brazilian fish

Leandro Melo de Sousa, Oliver Lucanus, J. Pablo Arroyo-Mora, Margaret Kalacska, Conservation and trade of the endangered 𝐻𝑦𝑝𝑎𝑛𝑐𝑖𝑠𝑡𝑟𝑢𝑠 𝑧𝑒𝑏𝑟𝑎 (Siluriformes, Loricariidae), the most trafficked Brazilian fish, Global Ecology and Conservation, 2021, e01570, ISSN 2351-9894,

𝐻𝑦𝑝𝑎𝑛𝑐𝑖𝑠𝑡𝑟𝑢𝑠 𝑧𝑒𝑏𝑟𝑎, also known as the zebra pleco, is a small sucker-mouth catfish endemic to the Xingu River in Brazil where its survival in the wild is threatened by habitat modification and overfishing for the ornamental fish industry. It is a highly sought-after freshwater ornamental species and one of the most commonly trafficked from Brazil.

To date, little is known about its global legal and illicit supply chains within the ornamental fish trade. Through a mixed methods approach (i.e., online survey, key informant interviews and web scraping), we examined the trade and trafficking of this species as well as the awareness of the international aquarist community and local and international stakeholders regarding its conservation. We also establish the historical timeline of zebra pleco keeping and breeding in captivity and assess whether commercial captive breeding can play an important role in the conservation of this species.

The retail price of the zebra pleco increased worldwide after an export ban in 2004 but have since decreased to an average of $US 155 (+/- $US 23 based on geographical location) per fish. Fishermen have been consistently paid relatively little ($US 7-60) for each specimen compared to the average wholesale price of $US 100 (+/- $US 94 over time). We conservatively estimate ~100,000 specimens are trafficked out of Brazil annually, of which half or more die in transport, and only a small fraction is seized by law enforcement in Brazil or internationally. The fishes are primarily smuggled from Brazil to Peru and Colombia and then exported internationally with the majority sent to China. The majority of aquarists (representing 35 countries) are aware the zebra pleco is both endangered and highly endemic. There was less awareness that buying wild caught specimens shipped from Peru, Colombia or elsewhere implies supporting wildlife trafficking. Nevertheless, nearly three quarters of respondents preferred aquarium bred specimens, if available.

The zebra pleco is being bred in captivity in high numbers in several countries, yet in Brazil it remains illegal to keep in private aquaria or to commercially breed them. Given the large success of hobby and commercial breeders around the world, H. zebra is well suited for indoor breeding facilities. We argue that implementing regulated local breeding facilities in Brazil, to increase the already large numbers reproduced in captivity worldwide, could decrease the demand for trafficked specimens, one of the primary factors threatening its survival. Given its iconic status among freshwater fishes it should be recognised as a flagship species of the Xingu River’s conservation.

Was someone looking for a schooling catfish?

Check out this mesmerizing school of striped eel catfish (Plotosus lineatus), captured by Abyss Dive Center Bali.

When young they form large ball-shaped schools of up to a 100 fish, but as they mature, they prefer to be alone or in smaller groups. On their first dorsal and each of their pectoral fins they have venomous spines to protect them from predators. Once mature, the venom can be fatal to humans!
