These fishermen wading and paddling hip-to-hip through the surging waters of the Kebbi River are learning what every avid trout angler knows well: opening day brings out a crowd. The occasion is the start of the traditional Argungu Fishing Festival in northern Nigeria, when the best anglers of the 170,000 Kabawa tribesmen gather to show their net worth, so to speak, and try to land the biggest catch of the day for presentation to Mera IV, Emir of Argungu. The Kabawa are known throughout Nigeria as great fishermen, an ability attested to as they come up with three-footers under such fish-routing conditions as these. Those skeptics who have long thought angling is impossible in the confusion of an opening day are advised to look sharply at the photograph above. See the proud Kabawa happily holding up his catch?
