Dispute over fish ladders to save species
Advocates argue scaly fish can pass through river barriers
By PRATCH RUJIVANAROM
RESEARCH to develop a ladder to help native fish navigate upstream in rivers facing major hydropower project construction may be the best hope for preserving fish biodiversity, says South East Asian Fisheries Development Centre (SEAFDEC).
Barriers caused by construction on waterways can stop fish migrating. Fishways help mitigate, but not eliminate, this problem.
ACIAR is supporting research in South East Asia and Australia to try and find solutions to complex natural resource management issue.
