Kiersten - Welcome to Ten Things I Like About… I’m Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. 

This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it.

We have made it to our tenth and final episode of Aba aba. I hope you have enjoyed our journey with Gymnarchus niloticus, come on you have to admit, it is fun to say that, because I have had a blast talking about this amazing fish. The tenth thing I like about this unbelievably cool fish is conservation.

As any of my longtime listeners know, I typically use the last episode to talk about the conservation status of the current animal or plant that we are discussing. This is the whole reason I started this podcast in the first place, to bring awareness to the animals and plants with whom we share this planet. We have to learn to live together if we are going to be good stewards of this amazing planet. Before we can learn to live together, we have to know what’s out there that is worth fighting for, and all the animals and plants I talk about are worth fighting for.

Let’s talk about what conservation looks like for the Aba aba. When we look at the IUCN Red List, the International Union for Conservation of Nature, Gymnarchus niloticus is listed as Least Concern. This means that no conservation efforts need be taken at this time. The last time that the overall population of the Aba aba was assessed was in 2019, so this information needs some updating. The North African population was last assessed in 2007 and is also listed as Least Concern, but once again we need updated information for this population. The Western African population was last assessed in 2006 and is currently listed as Least Concern. The Eastern African population was last assessed in 2003 and is listed as Vulnerable. Vulnerable means that adult population numbers are decreasing. 

Overall and in the Western and Northern populations the population trends are unknown, so the Least Concern classification may be incorrect. What’s interesting is that the Eastern population that is labeled Vulnerable also has no population trend data. What does this mean? It means we really don’t know how many aba aba are out there and if they are holding their own as our plants changes.

The IUCN does list the threats to the Aba aba and those include dams, water pollution related to the military and agricultural industry, logging and wood harvesting destruction of habitat, and overfishing. Natural climate impacts are droughts. The Aba aba relies on the seasonal flooding of rivers for breeding season. The overfishing impacts the Eastern population because the local humans use Aba aba as a food source in this region.

Currently there are no conservation plans being implemented in any regions of residence, with the exception of small grassroots campaign in the Eastern population region informing local fishers about the risks of overfishing the Aba aba. 

Another threat to the wild population of the Aba aba in collection for the aquarium industry. Gymnarchs niloticus is a fascinating fish that many people fall in love with when they see them in a zoo or aquarium or learn about them from educational resources like this podcast. It’s great to develop an appreciation for nature after learning about a specific specie, but letting that appreciation grow into a need to possess that species can be disastrous. As I talked about in the last episode, Aba abas are not suitable for the home aquarium, but the market still exists.

Some people think they can make it work even if they don’t have the correct size tank, or offer the type of food they need, or realize how dangerous Aba abas can be. They purchase a fish. And when it dies, they purchase another and so on and so on. Most of the time the Aba abas collected are so small and fragile that they are bound to die in transport or in the home aquarium.  Collectors will come back for more and they aren’t just taking a few out of each nest they come across, they are taking all the babies and may even kill the adults to sell for food. 

There is some discussion about how to create an aquaculture program with Aba aba in response to the use of Aba abas as food.
