【 摘 要 】

Cage aquaculture that has been growing enormously in Lake Maninjau, West Sumatera, Indonesia, is supposed to have an impact on benthic fauna including Corbicula moltkiana, the species of bivalves. The objective of this study addresses the population structure, growth and production of C. moltkiana that describing the impact potential of cage aquaculture activity. The result show that annual 2013-2014 production [P] of C. moltkiana were 465-1559 g AFDM m-2 y-1 and the annual biomass [B] was 183-453 g AFDM m-2, resulting in P/B ratio of 2.54-3.44 y-1. Even though the P/B ratio was not consistent with the cage density level, as consequently of different L∞ in determined zones. The increased cage aquaculture activity that marked by adding number of cage from -1 to > 675 cages km-1 impact to decrease of biomass [B] and production [P] of C. molktiana.
