Hard pulling fish!

The Sagai is a hard fighting fish much like most trevally species and it is also a popular eating fish, unlike most trevally species that has tough tasteless meat, the Sagai’s meat are soft and tasty.

They are a popular target species in the east coast states of Malaysia such as Pahang where Kuala Rompin is situated.

Angler often target them with micro jigs or live bait and to a lesser extend, on fly.

Tackle used must be sufficient to stop them from taking cover in underwater structure on their first run, especially on reefs and wrecks.


Fish in photo above was caught using the bottom ledger rig on very light line.

Commercial importance
A commercial specie sold at high prices. However, rarely seen in the markets in large quantities.
