Millport and Crocodile Rock

Harbour wall · Salt water · in The Firth of Clyde

The bay and old quay at Millport on Great Cumbrae, with the painted boulder the island is known for on the shore beside it and rock, weed and shell ground all round the bay. Sheltered water inside a firth that is itself sheltered.

Safety: cold water shock — can cause serious injury or death. One more point applies here.

What each one does, and what reduces it ↓

FishingHQ describes what this place is, not whether you may fish it. Access, permits and who to ask.

What you can catch here

Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

What these strengths mean
Regular local target
Fishing sources describe this as a normal local target here, not merely as caught.
Seasonal
Well supported, and concentrated in part of the year rather than spread through it.
Recorded here
At least one credible public account of this species being caught here. That is all it means.
How breadth is counted
A fish documented at six marks is shown as six marks: breadth never raises the strength on its own. A fishery account describes the fishing; a recorded catch reports one specific catch. How evidence is weighed.

Fish documented nearby, not here

Nothing below has been documented at Millport and Crocodile Rock itself. Each one has been documented at a named place on the same ground, and the places are listed with it. Treat this as what the water around here holds rather than as a catch list for this mark.

Also documented at neighbouring places

One or two accounts each, on the ground around here. Enough to know the fish is caught in these waters; not enough to say anything about this place.

From the shore

How people fish it

Practised here: Sea fishing.

Methods the sources name for this ground. Each one is explained in full on its own page.

  • Float fishing

    Suspending a bait at a controlled depth beneath a buoyant indicator — the most visual, most controllable and most widely applicable method in angling.

  • Light rock fishing

    Ultralight lure fishing from the shore with tackle rated in single grams — a discipline that catches the fish everybody else steps over, and one FishingHQ held every component of and had never named.

  • Spinning

    Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.

  • Ledgering

    Fishing a bait on the bottom held by a weight, with no float — the simplest way to fish at distance, in depth, or in wind.

The ground and the water

The ground
The bay and old quay at Millport on Great Cumbrae, with the painted boulder the island is known for on the shore beside it and rock, weed and shell ground all round the bay. Sheltered water inside a firth that is itself sheltered.
Exposure
Sheltered inside the firth, open south across the Tan.

Through the year

Mackerel and pollack in summer; the rest through the year.

The months the sources attach to each species here. Where a species carries no season it is listed underneath rather than assumed to run through the year.

The months in which each species is recorded as caught at this location.

Safety

Cold water shock — Can cause serious injury or death

The deep basins hold cold water year round and the surface warms only thinly. Immersion produces an involuntary gasp and loss of breathing control within seconds, in water too deep to stand in and frequently out of sight of anybody.

What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person, do not go out alone, and treat summer water here as cold water because at any depth it is.

Worse when:

  • In the sea lochs, where deep cold water lies immediately below a thin warm surface layer.
  • Out of season, when there is nobody else afloat to see an incident.

Boat safety — Can cause serious injury or death

Wind funnels down the steep-sided sea lochs, accelerates, and blows in a direction set by the topography rather than by the general forecast. Conditions that were flat at launch become unworkable within an hour with no change in the synoptic picture.

What reduces it: Plan for the loch's own wind rather than the firth's forecast, fix a turnaround time and an escape shore before launching, and treat any increase in wind as the start of a trend rather than a gust.

Worse when:

  • In the narrows and at loch mouths, where wind against a strong tidal stream produces a short steep sea.
  • On a long crossing with no escape shore under the lee.

Rules and access

FishingHQ does not know the current access position here. Sea angling in Scotland is not rod-licensed, but access rights under the Scottish Outdoor Access Code carry responsibilities, and harbour, local authority, marine conservation and fisheries measures all apply and all change. Check the current position with the Marine Directorate, the harbour or local authority and the land manager before going.

Who holds the answer:

  • The Scottish Government Marine Directorate, for sea fisheries measures in Scottish waters.
  • The harbour authority or land manager, for access to the structure or the ground.
  • The local authority, for shellfish harvesting classification.
  • Marine Directorate of the Scottish Government, for sea fisheries measures, marine protected areas and spatial management within Scottish waters.
  • NatureScot, for designation and management of the protected sites within the firth.
  • The relevant district salmon fishery board, for salmon and sea trout in the rivers entering the firth and in the coastal waters covered by their district.
  • The harbour authority or trust at each port and pier, where fishing is from a structure or a small craft is launched.
  • The Maritime and Coastguard Agency and the RNLI, for safety guidance in these waters.

Positions are approximate by design — they are capped at about a hundred metres and describe where a named public place is, not where fish are and not a mark.
