Tides

High tide pushing into mangrove systems is critical — jack spread across structure only on the high water

Time of Day

Last hour of the tide and the first hour of the run-out produce the biggest fish; night fishing is excellent

Conditions

Warm, turbid water 24°C+; jack are bolder in lower visibility and after dark

Structure

Mangrove root systems, submerged rocks and snags, bridge pylons, log jams in river bends

Technique

Cast hard bodies into mangroves and retrieve immediately — a lure sitting still next to cover is about to get bitten

Pro Tip

Tighten your drag before casting — a jack will be back in the snag within 0.5 seconds of the strike. An underpowered hook-set guarantees a bust-off.
