I was fishing at one of the three ponds at Tmn Perling last week. The ponds charge ard RM32-38 for 4 hours of fishing. They sell live prawns at RM0.70 for bait.
I don't know which pond you are refering to. I went to Brother fishing pond and landed myself 2 KBLs and 1 Kim Chew with live and peeled prawns. I believe I could have landed more if I adopted their fishing technique earlier. I was at the right spot ( A particular corner where the KBLs were hiding) but I was not using the right rig.
I was using the usual spinning rig (split shot with single hook) but I noticed a regular using similar rig less the split shot. He caught about 6-7 KBLs in two hours. I removed the split shot and was immediately rewarded with one too. Nonetheless it was already too late
The uncle had cleared most of the fish liao. I am quite sure his rig worked because there were others who were not getting any bite using different setup (Float mostly)
There was also this Singaporean uncle there who was floating with fish meat/live prawn combo at the middle of the pond. He landed the champion fish of the day - A 3kg KBL. He mentioned that he lost a huge groupa earlier.
Like any fishing pond, the spot is very important. Otherwise, you will just be fishing blindly.
