Day 7: 1/4/2010

Hit a bunch of rivers today about an hour away from were we are staying. We started of by looking for a new tributary of the Rio Costa Rica. We found one and it had some nice Septs and Neets in it. Unfortunately, the bugs were awful and we got eaten alive. We then stopped at a river in between Guapiles and Guacimo where a train used to cross over a bridge. It was small, but had a deep pool with lots of fish. The only fish breeding where septs, but the river also contained Wolf Cichlids, Dovii, Convicts, Tuba, Neets, and Astatheros alfari.

It was then off to the Rio Herediana. When I first got out of the car, I saw a pair of Dovii guarding their fry. Unfortunately, by the time I got my snorkel gear on, they were gone. Dovii seem to move their fry a lot up and down the river. The only other fish breeding in the river were Cryptoheros septemfasciatus.

We then went to the Rio Guacimito. Unfortunately there were spear fisherman and it was decided it wasn’t safe to enter the river.

We decided that on our way back to the field station we should explore the area north of Puerto Viejo de Sarapiqui and try to find a new tributary to the Rio Puerto Viejo to snorkel. We didn’t find one, but we saw some neat stuff on the way.
