Location-confusion?

Michael Koeck posted: 26.08.2011

Hi friends, am a litle bit confused: I breed some strains of Skiffia multipunctata; among them is one called Tangancicuaro, another Lago de Camécuaro, Tangancicuaro...my question: are these the same locations? Are among us the people who sampled the fish, took them to Europe and who are able to answer my question?
Another mystery-location for Ataeniobius toweri : Lago de Creda (or Credo, or del Creda, Credo...); nobody seems to know where these fish come from, didn't find a location with this name, or a similar like Cerda, cerdo, Oredo...in the range of toweri, but as far as i know, the strain isn't older than a few years, so: who can solve the mystery?
Last question: How often has Zoogoneticus tequila been sampled? I heard of one time, 1992; then I read 1990...two collection-cates? Or only confusion? Or is 1992 wrong? Who can help me in this situation?
All the best, Mike

For the first one I don't know...

For the second one I will look in my doc.

For the third one, you can read : Aquarium-reared descendants of wild-
caught  fishes  collected  by  M.  Smith, C. Rodriquez,  L. Butler,  a n d  D.
Lambert, 26 February, 1990

And i think it was the first and last time it was found in Teuchitlàn...

Michael: When I visited the area in 1991, I found multipunctata in a small sewage ditch a few meters from Lake Camecuaro. This was a very colorful (strong golden yellow males) population, possibly due to the turbidity of the water. At this time I did not observe any multipunctata in the lake itself. Fish from this collection were imported to Scandinavia and widely distributed at "Skiffia multipunctata Lago de Camecuaro 91". I believe descendants of these fish are still in the hobby. At later visits to Camecuaro (1994 and 1995), the ditch was removed, but multipunctata could be seen in high numbers in the springhead pools along the lake. These fish show much less coloration than the ditch-population did, but I suspect this is more caused by environmental factors (i.e. crystal clear water), rather than genetics.At the same time ('91), I observed multipuncata in a small river that crosses the Tangancicuaro - Zacapu road at the eastern edge of the village of Tangancicuaro. This population was colorless and lived in open free-flowing water. At a later visit to this site, just a few months later, multipuncata was not to be seen, only Z. quitzeoensis in good numbers (probably natural population dynamics). No fish from this location were brought to Europe by me.In conclusion: While I cannot exclude that the river at Tangancicuaro may be connected to Lake Camecuaro, I would recommend treating those as separate locations.By the way, I also took part of a team with researchers of the University of Guadalajara that found and collected Z. tequila at Rio Teuchitlan April 19th 1991. Fish from this collection were taken to the Limnological Institute at Chapala, but I do not believe these were further distributed.

Thank you Andreas!I very precise reply, and it helps a lot. "Your" Camecuaros are still in the hobby, indeed. Since last year even in Austria:-) For me, both locations have quite similar colours, the Camecuaros appear a bit slender, but this is just a personal opinion, and my young fish will proof this when adult. I have some from a location called Rancho Nuevo, too, and after all: All populations I know, including the ones from Hidalgo aso, look all very similar maybe due to its very close distribution range, but as far as I know, this area is the only region left with multipunctata...Very interesting things concerning tequila, too! I think most of us didn't know about an earlier collection data than 1992! But I am d'accord with you: They wouldn't have been distributed. Nevertheless it would be interesting where these fish had gone.
