Here in Uganda, fishing isn’t done exactly how I learnt to do so as a kid. Back then, I always used a rod and hook, but here, we use nets.
Thankfully, the nets often leave fish unharmed, so we can take a look at our catches, get a few useful measurements, and return the little critters to the lake so they can continue on with their underwater lives.
The ‘Ekeje’ (Haplochromine cichlids) are one of my favorite discoveries in our nets up to date. The males have shiny red tales and pretty orange dots on one of their fins. These colorful dots are actually called “egg spots” because they mimic the eggs of females. But why have dots on a males’ fin that look like eggs?
Well, the Ekeje are mouth brooders, so females release their eggs, catch them in their mouths, and then a male has to come fertilize them. Thinking these spots are eggs, the females are tricked and approach them, which allows males to fertilize.The orange egg spots on this fin are what allow this species to continue reproducing!
Blue lips are another one of my favorite fishy discoveries. And yes, they are called blue lips because their lips really are blue! This is not because it’s cold here, but rather, because for this species, blue lips are what females consider sexy. In fact, some recent research suggests that the bluer the lips, the more attractive the fish!
But bright colors aren’t everything here… I’ve also discovered one amazing brown creature referred to as the ‘Mamba’.
When I first heard ‘mamba’ I immediately thought snake, but this is actually the local name for a lungfish. These fish are some of the oldest species in the world still alive today. In fact, they’ve been around since the dinosaurs were on Earth! These fish have some of the earliest documented forms of lungs, which allow them to breathe air at the surface. This, and a number of their other traits, make scientist believe that this species was part of the transition between those that live in water and those that live on land.
After setting and pulling these nets so many times, they are bound to have holes; and of course, they need fixing when this happens. Later this week, I’ll be visiting with a man named Musenze who is the local net mender. Keep posted for pictures and stories of this encounter!
