Warm months around bait

🌡️ Water temperature

Warm water of 19–24 °C pushes them inshore; find the temperature/colour break.

🥅 Landing

Net or lip-gaff at the boat; on the rocks lead it to a gulley on the swash. Keep the line tight — they throw hooks.

♻️ Release

Bleedable table fish are usually kept; if releasing, minimise the fight, keep it in the water and revive before letting go.
