Inshore or offshore? The Neolithic fishermen of Ra's al-Hamra (RH-6, RH-5, Muscat, Sultanate of Oman)

Ra's al-Hamra 6 (RH-6) and Ra's al-Hamra 5 (RH-5) are two of the most important Neolithic coastal sites in the Sultanate of Oman. Located in the capital Muscat, they have supplied an important corpus of fish bones and revealed a high taxonomic richness in the different assemblages. The results provided information on fishing practices that held an important role in the subsistence strategies of the inhabitants during the two millennia of occupation (sixth to fourth millennia BC). Pelagic species (jacks and kawakawa/tunas) were largely dominant throughout both occupations, calling into question the interpretation of inshore or offshore fishing; these fish could have been caught with a hook-and-line or by setting nets at a reasonable distance from the coast. However, the inhabitants also had to supplement this subsistence by catching demersal fish and small fish, caught from the cliff, in the estuary or the mangrove. At both sites, the inhabitants clearly exploited the different nearby inshore environments: coastal open water, reefs, estuary, and mangrove. Moreover, the high fish richness (69 genera at RH-6; 35 genera at RH-5) indicates that both sites could have been occupied on a year-round basis.
