Running the guantlet

Unread postby Johan van Rensburg » Mon Nov 30, 2009 2:13 pm

The recent wet spell in Kruger had (debatable) beneficial consequences for some... the rising water level causes a spawning urge in the African sharptooth catfish Clarias Gariepinus to start migrating upstream (normally) immediately after the first heavy showers of the rainy season... they love shallow water and vegetation to spawn in.

Such was the case at the causeway below the Pioneer hide near Mopani, Friday 20 November. However, “upstream” is restricted due to the dam wall, so, downstream became a viable second option. The catfish somehow sensed that their pond was overflowing, offering suitable spawning habitat on the downstream side of the causeway. They gathered there in numbers to cross over in the very shallow overflow. Soon the Nile crocodile realised there was one of its favourite food items on offer...

Somehow the catfish detected the presence of the crocodile as well as that the best places to run the gauntlet being the shallowest part of the causeway.

There couldn't have been more than 2 cm of water, but it was enough for the catfish to power across the causeway and into the safer portion of the stream where it would eventually participate in a spawning frenzy.

The croc would react to the splashing, arriving at the catfish's departure point too late to be effective, while behind the crocodile, another catfish would sneak across. Eventually the croc gave up the effort and retreated, leaving the causeway to the catfish.

Obviously we were rooting for the croc... I mean, the shots of a crocodile catch would have been much more exciting that those of sneaky catfish outmaneuvering the mighty Nile crocodile! :lol:

We came across the most amazing sighting over the causeway behind Shingwedzi on our recent trip. The river was flowing over the causeway and the crocs where lined up with mouths open, catching fish as they came over the bridge. One croc was even on the bridge!! What amazed us the the croc would allow the water to run through his mouth, and then when a tiny fish touched his jaws, they would snap shut. A remarkable sighting indeed and one that goes down as one of the highlights. Birds also enjoyed the feast.

Thats a monster and it certainly looks as if that is the area around Sunset dam and I know there are some pretty big crocs in there!

Poor crocky Anne-Marie. :cry: :cry:
I would think he can survive with part of his tail missing, but I'm not an expert! :hmz:


This fella was seen at Sunset Dam March 2011.
