Hey Charles
First Blacktip Trevally (
caranx heberi) is quite a widespread fish in the Indian Ocean and western Pacific regions. In Oman I found them to be particularly common and easy to attract with topwater lures. In spots in Indonesia they tend to lie deeper in the water column and are best fished for with small jigs. Fishbase:
http://fishbase.org/summary/Caranx-heberi.htmlThe Pompano-type trevally group is a nightmare of confusion of common names, and also mis-identification. The African Pompano (
Alectis ciliaris) has a maze of common names, see:
http://fishbase.org/comnames/CommonNamesList.php?ID=988&GenusName=Alectis&SpeciesName=ciliaris&StockCode=1004. The confusion is with the Indian Threadfish (
alectis indica). Both often seem to have the same vernacular name!
I have never caught either with a top water lures but I have when jigging normally at mid-water depths. They pull like hell!
In my (mostly Asian) popping experience, and from chat and reading other reports, the most likely trevallies to take a lure when you are targeting GTs are:
Bluefin Trevally
Bludger
Orange-spotted Trevally
Yellow-spotted Trevally
And also, Big-eye, Golden, Brassy and Tille.
