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

given during fish surveys and for providing fisheries related information of Putrajaya Lake.

Fisheries resource surveys were conducted by staff from FRI GL: Mr. Mustafa, Mr. Ghani, Mr. Hassanal & Mr.
