Tunisia issued one stamp in 2015 for Euromed which shows us a mosaic of a second century Roman Trireme, likely from Africa Province. Most probably this vessels were used for the transport of persons and products along the coast of Tunisia and between Tunisia and the Roman Imperium. The mosaic is today in the Sousse Archaeological Museum.
Wikipedia has on this mosaics in Tunisia:
Ceramics and pottery, skills developed and practiced for many centuries under the prior Phoenician-derived, urban culture, continued as an important industry, both oil lamps and amphorae (containers with two handles) were produced in quantity. This pottery, of course, complemented the local production of olive oil, the amphorae being valuable not only as hard goods, but also useful for oil transportation locally and for export by ship. Numerous ancient oil presses have been found, producing from the harvested olive both oils for cooking and food, and oils for burning in lamps. Ceramics were also crafted into various statuettes of animals, humans, and gods, found in abundance in regional cemeteries of the period. Later, terra-cotta plaques showing biblical scenes were designed and made for the churches. Much of this industry was located in central Tunisia, e.g., in and around Thysdrus (modern El Djem), a drier area with less fertile agricultural lands, but ample in rich clay deposits.
The export of large amounts of wheat, and later of olive oils, and wines, required port facilities, indicated are (among others): Hippo Regius (modern Annaba), Hippo Diarrhytus (modern Bizerte), Utica, Carthage, Curubis (north of modern Nabeul), Missis, Hadrumentum, Gummi and Sullectum (both near modern Mahdia), Gightis (near Djerba isle), and Sabratha (near modern Tarabulus [Tripoli]). Marble and wood was shipped out of Thabraca (modern Tabarka). Ancient associations engaged in export shipping might form navicularii, collectively responsible for the commodities yet granted state privileges. Inland trade was carried on Roman roads, built both for the Roman legions and for commercial and private use. A major road led from Carthage southwest to Theveste (modern Tébessa) in the mountains; from there a road led southeast to Tacapes (modern Gabès) on the coast. Roads also followed the coastline. Buildings were erected occasionally along such highways for the convenience of traders with goods and other travelers.
Other products of Africa Province were shipped out. An ancient industry at Carthage involved cooking up a Mediterranean condiment called garum, a fish sauce made with herbs, an item of durable popularity. Rugs and wool clothing were fabricated, and leather goods. The royal purple dye, murex, first discovered and made famous by the Phoenicians, was locally produced. Marble and wood, as well as live mules, were also important export items. Local trade and commerce was conducted at mundinae (fairs) in rural centers at set days of the week, much as it is today in souks. In villages and towns macella (provision markets) were established. In cities granted a charter the market was regulated by the municipal aediles (Roman market officials dating to the Roman Republic), who inspected the vendor's instruments for measuring and weighing. City trading was often done at the forum, or at stalls in covered areas, or at private shops.
Expeditions ventured south into the Sahara. Cornelius Balbus, Roman governor then at Utica, occupied in 19 BC. Gerama, desert capital of the Garamantes in the Fezzan (now west-central Libya). These Berber Garamantes had long-term, though unpredictable, breakable, contacts with the Mediterranean. Although Roman trade and other contact with the Berber Fezzan continued, on and off, raid or trade, extensive commercial traffic across the Sahara, directly to the more productive and populous lands south of the harsh deserts, had not yet developed; nor would it for many centuries.
