Aquatic Weed Symposium
Springer Online Journal Archives 1860-2000
Abstract A historical insight into the connections between Portuguese researchers working on aquatic weeds and the EWRS Symposia (1964-1998) is given. A review is provided of the major aquatic weeds in Portuguese waters, including fluvial systems, reservoirs, drainage and irrigation canals, and rice fields along with the types of control and aquatic plant management practised in Portugal. Aquatic weed control in Portuguese waters is performed mostly by mechanical means, in spite of several experimental attempts at chemical control and biological control with fish and insects. Aquatic weed studies in other Mediterranean countries are also referred to.
