A brief report from the first collecting day in the Amazon Oct. 2009
by Tom Christoffersen
Yesterday, first collecting day ......
We went out of Iquitos, followed the road (the only one in the area) to Nauta, and walked to this biotop:
Beneath the surface it looks like this:
pH: 5,06 Conductivity: 18 microSiemens/cm Temperature: 27,2 °C
The first fish, caught with a hand net, was a female Apistogramma sp."Schwarzbrust"
(Update: Described by Römer, Duponchelle, Diaz, Davilla, Sirvas, Catchay & Renno in 2011, and given the name
With a bigger net, we also got males:
We went to the nest biotop; a restwater pool where the locals had cut down the surrounding vegetation:
pH: 5,32 Conductivity: 10 microSiemens/cm Temperature: 30,2 °C
We got some nice Apistogramma sp. "Masken" (Update: Described by Römer et al. in 2013, and given the name
This is males:
and a female:
Then another biotop, just about 20 km from the city of Iquitos:
Remember, this is the end of the dry season, not much water left:
The ground is fine, white sand with lots of leaf litter
Beneath the surface:
pH: 3,80 (!) Conductivity: 59 microSiemens/cm Temperature: 29,1 °C
In the left bottom corner, there is an Apistogramma!
Beautiful Apistogramma atahualpa:
We also got many beautiful Pyrrhulina (cf.) spilota in the net:
and some Rivulus sp. in this water :
Today we are preparing for the next expedition; tomorrow we will go to Mazan and up the Rio Napo.
Maybe more to come......
