Aba aba: Human Cultural Connection
Episode 124
Wednesday, 20 August, 2025
Summary: Have Aba aba impacted human culture in the areas they are found? Join Kiersten to find out! For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Show Notes: “Some Ecological Factors of the Tropical Floodplain Influencing the Breeding and Conservation of Gymnarchus niloticus (Cuvier 1829): A Review,” by Oladosu O.

(Piano music stops) 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. Through the last few episodes I think I have painted a pretty good picture of the Aba aba’s anatomy and natural history. I have fascinated you with the amazing way they hunt and today, I thought we’d investigate how this fish impacts human culture. The eighth thing I like about the Aba aba is how much humans value this fish. Animals of all kinds impact other animals that reside in their habitats. Aba abas are no exception to this and they have become important in many indigenous human cultures that live where these fish are found. The first thing you may think of when speaking about how fish impact people is as food. And no doubt, we, as do many other animals, eat fish. Aba abas are highly prized as a food fish. They can grow quite large, creating a lot of meat. A five foot long fish means a bunch a meat. They are an oily fish, but several sources say they are tasty. Smoking them seems to be delightful way to eat them. In West Africa they are also eaten raw. Some cultures also gift them, alive or dead is not entirely clear, my guess is probably both. Suitors will gift them to a bride’s family symbolizing respect and goodwill. Nothing like a long, electrical fish to start off a relationship right! Certain cultures, such as the Yoruba of West Africa, will also present them to community leaders as a sign of respect during community celebrations. The introductory paragraph of the scientific paper “Gross Anatomy and Histological Features of Gymnarchus niloticus from the River Niger at Agenebode in Edo State, Nigeria,” states: Gymnarchus niloticus commonly known as the Nile knife fish, trunk fish, or aba is one of the most valued fishes along the River Niger by the inhabitants of Agenebode and Idah. The trunk fish is highly valued for its good taste, rich nutrients, though oily flesh, ability to grow as large as 25kg, highly valued in customary rites for marriage and community celebrations. End quote. In Yoruba it is known as Eja Osan while in Hausa it is known as Dansarki which means son of a king. These names are a sign of respect for this amazing fish. (Do please forgive me if I mispronounced any words.) Since Gymnarchus niloticus is such a large fish and edible, a lot of research is going into whether it would be a good candidate for an aquaculture fish. Is raising them in a farming situation beneficial for protein production and economically sound? The answer is not yet decided but it would be extremely difficult to do in an aquarium situation since the fish get so big and they are aggressive to other animals. Someone did discover that polyculturing Aba aba with Tilapia might be possible. They can be kept together in the same space, feeding the tilapia food and then letting the Aba aba eat the tilapia fry. Tilapia grow quickly and create a lot of fry. The Aba aba can eat the tilapia fry but not all of them. Then both species can be harvested. Whether this is possible long term allowing Aba aba to reproduce is unknown, as they are a solitary species, it may not be functional. It is worthwhile investigating though. Current fishing practices of Aba aba often includes killing the adult and harvesting the young from the nest. This is an unsustainable fishing practices and to help this fish and humans weather the future of changing climate, we will need to work together. Some researchers believe that the Aba aba is a good candidate for an aquaculture food fish. It grows quickly and is a hefty fish, but it needs specific conditions and is a carnivorous fish, so much more planning and research needs to be done. Another way fish impact humans live is in our home aquariums. Keeping fish can be a rewarding and relaxing hobby, but is the Aba aba a good candidate for the home aquarist? I will answer this question next week. Thanks for listen to week eight of the Aba aba. My eighth favorite thing about Gymnarchus niloticus is their human cultural connection. If you're enjoying this podcast please recommend me to friends and family and take a moment to give me a rating on whatever platform your listening. It will help me reach more listeners and give the animals I talk about an even better chance at change. Join me next week for another exciting episode about the Aba aba.
