The ancient fish fauna from Asa Koma (Djibouti) and modern osteometric data on 3 Tilapiini and 2 Clarias catfish species.

Résumé

The fish 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 fish 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 fish 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 fish 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 fishing grounds, and the fishing methods that may have been used. Finally, the possible fish preparation and fish processing methods are discussed.
