The roles of the Department of Fisheries Malaysia include providing technical advice, supplying fish seedlings for public restocking and conduct fisheries resource survey of the lake.

Fishing PressureFishing effort mainly from:
• sanctioned fishing competitions• illegal fishing• occasional scientific surveys • removal of undesirable fish
Challenges and prospects for scientific studies
Carrying capacity of lake for fisheries Effectiveness of public release programs Release of foreign species by the public Migration of fishes in/out the lake?
Invasive species, breeding seasons Fishing pressure vs. protection of
important fish species
Suggestion and Recommendation A better lake research and monitoring
program – periodical data is needed Involvement of local universities in
fisheries study of Putrajaya Lake Closure of Putrajaya Lake to fishing
activities during normal days (except during annual fishing competitions)
Acknowledgement Perbadanan Putrajaya for assistance
