Time of day: Any time the pots are soaking; check them regularly.

Weather: not fussy about wind; rain and runoff help.

Seasons partly come from Coastwatch report mentions, not catch numbers.

Around Scarborough and the Redcliffe Peninsula

Our local Redcliffe Peninsula notes come from local fishing columns and reports, and for mud crab they differ from the South East Queensland picture. Around Scarborough the best months are November to March, with April and October also worth a try.

Picked because the water each spot reaches suits mud crab (our habitat match), not from catch reports. Each spot links to its place on the area page; tide times are for the place our forecast reads for that spot.

How to catch mud crab: best bait and gear

  • Mullet
  • Fish frames
  • Chicken frames

Mud crab gear

Heavy pots with enough rope for the depth. Max 4 pots/dillies per person, tagged with surname and address, light-coloured float at least 15 cm marked with surname. No inverted dillies.

Good to know about mud crab

Catch rates fall below about 20 °C water; rain pushes crabs downstream. Pumicestone and the Brisbane River produce longer into winter than the bay creeks.
