Potamotrygon/Paratrygon natural distribution locations?

[Wimmels]

Hello People

I was looking/searching on internet for a map of southern america where one can see where the different species of the potamotrygon and paratrygon species occur but I can't find any.

I momentarily keep mostly Malawi cichlids and I can find any fish I have its distribution in the Malawi lake.

I find this to be really interesting data, and if I should go on vacation someday I would like to know what species of fish I can find at the place I am going to.

Can someone help me out here?

I don't think there is one.. probably because so many species regionality stretches across hundreds of rivers and tributaries in the amazon.. It would almost be impossible to pinpoint collection zones. With flooding, and rivers changing their routes of water flow each season.. it's just too spontaneous..

I started a google map, where users could input information and add 'flags' to mark where certain species of rays are located.. It flopped, no one worked on it but me. I also made some maps on my website that had collection zones, but they were only applicable to rays like Leopoldi and Henlei, that have known isolated collection zones.. Rays like Castexi and Motoro, are impossible to map.

If you want the river locations of where the holotypes for each species were collected and recorded, could try this link..

Ah thank you. At least your site mentions river names and such. Pretty much a shame that the map Thingy flopped.

Why I ask this, is that a certain group here in Holland goes frequently(yearly or once every 2 years) to Colombia to catch some rare Cichlids. They let a local exporter ship it to them once they are done catching

I was thinking to go with them once and see if I can catch me some rays instead of cichlids, but I will need to know what species I can find there and where(which rivers) I can catch them.

You might talk to Ernesto here, he's been there to catch rays.. so has Kevaldo.

Some of the vendors as well, such as Oliver Lucanus from Below Water, and George from Shark Aquarium.. have led tours to catch rays/cichlids in those areas.

I would also inquire to mikofish.com and talk to Ivan Mikofish, as he infact leads expeditions to swim/capture FW stingrays in Venezuela, and likely other countries, too.

that would be a awesome trip.... catch your own rays... best way to cherry pick a ray is right from the river... imagine if you could do that in brazil for black rays
