Growth, reproduction, and lifespan were reviewed in three indigenous small-sized fishes in Lao PDR belonging to different taxa, Parambassis siamensis (Ambassidae), Rasbora rubrodorsalis (Cyprinidae), and Clupeichthys aesarnensis (Clupeidae). All three species were estimated to have short lifespans (C. aesarnensis, while higher temperature was considered to lead to earlier maturation and downsizing of maturation size, evolutionary downsizing owing to overfishing was of another concern. As the recent economic development and population growth within the country has led to an increase in fish demand and deterioration of the environment, all the species are considered to be in danger of stock decline. Therefore, in the present study, some ideas for stock managements for these species based on biological aspects are discussed.
