Juvenile black marlin can be caught in Kuala Rompin. They are fairly common although sailfish outnumber them by a huge margin so chances are you’ll have a sailfish at the end of your line.
Bigger blacks are often a handful on lighter gear meant for sailfish and not surprisingly, many are lost after a lengthy battle much to the chagrin of the angler.
Rompin’s black marlin are more commonly caught at the beginning of the season (March/April) and towards the end of the season (late October/November). We have however, caught marlin even in the months of June and July.
They are also usually located farther out than the sailfish which are more willing to venture nearer inshore. Having said that, Geoff from Australia did hook a 60kg marlin very close inshore while fishing with us in 2017.
The marlins here are mostly juveniles between 20kg to 40kg although larger fish around 100kg have been caught.
