ABSTRACT
In 1964–65 the industry was temporarily revitalised by the change in the flow of the river and an exceptional yield was obtained. At Battor, about half the adult females dived for clams and two thirds considered it as their main source of income. The greater growth rate of clams in the upper section of the stretch of the river induced a seasonal migration of women from downstream. The most important beds were the upstream near Akuse at Torgome, Asuchari, Alaboke, Volivoe and Duffor where clams were transplanted in 'farms'. The industry upstream was sufficiently prolific to support a large number of traders, most of whom were also clam divers. The number of women diving for clams per day throughout the season averaged 1515 in 1954, 1400 in 1956, and 1181 in 1957, a year of little industry.
