The ancient fish fauna from Asa Koma (Djibouti) and modern osteometric data on 3 Tilapiini and 2 Clarias catfish species
Documenta Archaeobiologiae, 2:141-160.
The fi sh fauna is presented from Asa Koma; a prehistoric site dated around 1800 cal BC and located in Djibouti
near Lake Abhé. The site comprises numerous hearths from which the fi sh bones that form the majority of the
faunal remains were recovered. Only two fi sh species occur, namely Oreochromis niloticus and Clarias gariepinus,
which are also the two major taxa occurring in the saline lake today. The skeletal element distribution and the
frequency of charred remains were analysed and, in addition, detailed size reconstructions were carried out. On the
basis of modern skeletons from 47 tilapia and 39 Clarias, the metrical relationship between fi sh length and individual
bone measurements (32 measuring distances for tilapia and 40 for Clarias) was established with the aid of
the “least squares method”. The equations are all listed for future use by other researchers. The fi sh and other fauna
do not allow a precise environmental reconstruction, but the large size of the Clarias possibly indicates less saline
conditions than today. Using the reconstructed sizes of the fi sh from Asa Koma, modern data on the behaviour of
the species, ethnographic and archaeological parallels, and palaeohydrological data, attempts are made to establish
the most likely season of fi shing, the possible location of the fi shing grounds, and the fi shing methods that may
have been used. Finally, the possible fi sh preparation and fi sh processing methods are discussed.
