Return to the
The first trip to Colombia in 2012 was also the
first time I had been in the Amazonian jungle. This trip I knew more
of what to expect having spent around 5 weeks at Steve's lodge outside
Leticia, Colombia. This trip Steve was kind enough to let us stay again.
Spent the day with Fred &
Diana at the Finca. Fished the stream at the bottom of Steve's land
- same place as last year. Collected mainly Nannostomus
trifasciatus, marble hatchet, a few knife fish about 4".
Shoals of Characin but not worth collecting. A couple of Hoplosternum.
A young Cayman could be heard fairly close by so we were on our guard
in case mum showed up.
Returned to the finca & collected some more
of the Rivulus pictured above. Also
fished further upstream. Despite fishing extensively in the mud but
only caught knifefish & Apistogramma.
One Rivulus was caught briefly but
prooved a good jumper & got away. He was not a very colourful specimen,
lots of small horizontal dots.
A day of local fishing for commercial fish
Collected in Rio Tacana tributary
end of road where we collected first last year. River level about the
same. Collected the usual - Nannostomus trifasciatus,
few marble hatchets, 4-5 scissortail characin with the colour in the
top half of caudal. Quite a lot of red Tyttocharax,
collected a few for later photography. Could have collected around 70-80
but they don't travel well. Some died on the way to the fish house.
Caught 1 pike cichlid but no more could be found.
We had heavy rain for a few days which prevented
collecting. The water levels in the tributaries & river rose to
about 2 metres higher than last year.
About a mile further down the trail a small puddle of water by a log netted a few Rivulus, not very colourful.
A little further a boggy area on the trail netted quite a lot of Rivulus, some quite large about 7-8cm. Males very colourful with body green with red horizontal stripes. Unpaired fins nice lemon colour.
We followed the trail up from the bog which was quite wide. We collected in small puddles, some by removing walkway planks. Quite large fish collected. These were R.elongatus. It was interesting to note these were caught on higher ground than R.rubrolineatus.
Returned to this biotope but fished in a culvert on the km road. Collected more 'Red Rivulus' near the edges which extended the distribution area of this species. Unable to follow the stream upstream due to barbed wire fence going into private land. This was a fast flowing stream. Quite deep under the culvert.
Tanimboca Reserve. This is literally over the
km road when following the road from the lodge to the km road. It's
a great place with trails around the reserve to various interesting
points like snake pens, streams & a nice shallow sandy based river.
Goran looks after this reserve & those considering collecting here
should ask permission first as a matter of courtesy. Followed trail
round to a small stream. Found small Rivulus.
All looked to be males but some had an ocellus so collected a good bag
full. Different pattern with red edges to outer margins of caudal fin.
These are location TACOL2013/7. Later they were identified as R.rectocaudatus.
This form was only found in this small stream. Very shallow biotope
with slow flow of clear water. Only small pre sexing out fish collected.
These have been grown on & bred in the UK but some problems have
been encountered in hatching eggs.
When we collected in 2012 the water
levels were a lot lower & the trail was a lot easier. We got to
the former damn pool & had to get over a fast, deep flowing tributary.
On the other side a tree had been cut down
More rain which swelled the rivers
so decided to give the jungle a rest.
Tried a couple of trails heading
in the direction of the areas we fished along the km road but didn't
find any water. It's likely the drainage flows further towards Nazareth
before entering into the main river.
A few years ago my friend Alan Green
was working in the fish house at Steves lodge when an Indian lady brought
in a red fish. Alan saw it was a Killie of some sort & looked like
an annual. We have been trying to find these
Collecting at km 9/10
This was a morning of collecting commercial fish. The biotope was an innocent looking river, quite shallow with a sandy base. Nice & easy to collect in I thought. Until I stepped on a gas pocket & went through it, disapearring in a jacuzzi of marsh gas. Not that pleasant but we managed to collect quite a few fish - Corydoras fowleri were big. These appear to be territorial & only a few loners were collected. Glass knife fish were quite plentiful here.
Trip to Iquitos, Peru
Last year we went to Iquitos by Rapido, a fast boat which usually does the trip from Santa Rosa to Iquitos in around 10 hours. This year for a change we decided to take the float plane which does the trip in about 1 & a half hours.
