Where squid are found inshore
Explainer · Last reviewed 2026-08-14
Squid come inshore for two reasons — to feed and to spawn — and the ground they use is decided by clean water, weed or sand to lay eggs on, and something concentrating bait.
Safety
Slips, trips and falls — Can cause injury needing treatment
The ground that holds squid inshore is harbour walls, quaysides, pier ends and rock edges, worked in the dark and frequently wet. Weed-covered stone and ink-slicked concrete are both genuinely slippery, and the drop is usually straight into deep water.
What reduces it: Gripped footwear, a light on the ground rather than on the water, and a habit of not moving backwards while playing a fish. Keep the working area clear of jigs, nets and ink.
Squid are oceanic animals that come into shallow water for particular reasons, and knowing which reason is operating explains where they will be.
FEEDING BRINGS THEM TO WHERE BAIT CONCENTRATES. Squid follow small fish, and small fish concentrate along structure, in the light of harbours, over reef edges and where current forces bait into a confined space. Anything that concentrates prey concentrates squid behind it.
SPAWNING BRINGS THEM TO SPECIFIC GROUND. Most inshore squid attach egg masses to something — weed, seagrass, kelp stipes, rope, wreck or the seabed itself depending on species — so the presence of suitable attachment substrate is a genuine predictor. Cuttlefish in particular move into shallow weedy water in the warmer months for exactly this reason, and their arrival is a seasonal event rather than a constant.
CLEAN WATER IS THE NON-NEGOTIABLE. Squid are visual hunters and they do not use turbid water. A coloured sea after a blow, or the plume off a river mouth, will empty a mark that fished the night before. This is the single most reliable negative indicator in squid fishing.
DEPTH CHANGES AND EDGES MATTER MORE THAN ABSOLUTE DEPTH. A drop-off, a channel edge, the end of a pier, the boundary between sand and weed — these are the features. Squid patrol edges rather than open ground.
AND HARBOURS AND PIERS ARE THE ORDINARY SHORE VENUE for a combination of reasons that all point the same way: existing lighting, deep water close to a standing position, structure concentrating bait, and rope and wall providing spawning attachment. It is not an accident that squid fishing worldwide is a harbour activity.
Clean water, an edge, and something to lay eggs on
Three conditions between them account for most of where squid are found close to shore, and reading a mark means checking all three.
CLEAN WATER FIRST, BECAUSE IT VETOES EVERYTHING ELSE. Squid hunt by sight and they avoid turbid water. A sea coloured by a blow, by run-off after heavy rain, or by a river plume will hold few squid however good the ground is. Conversely, water clearing after a period of coloured sea is one of the more reliable positive signals there is. Checking clarity before anything else saves wasted sessions.
AN EDGE SECOND. Squid patrol boundaries rather than open ground: the end of a pier, the drop-off at the edge of a channel, the boundary between clean sand and weed, the outside of a harbour wall where the bottom falls away. A mark that offers a defined edge with deep water on one side of it is a better proposition than open shallow ground, whatever the season.
SPAWNING SUBSTRATE THIRD, AND SEASONALLY. Inshore squid and cuttlefish attach eggs to weed, seagrass, kelp, rope and structure, so ground offering those materials draws them in at the right time of year. Cuttlefish in particular come into shallow weedy bays in the warmer months to spawn, which is a seasonal arrival rather than a permanent population.
CURRENT IS THE MULTIPLIER. Flow that concentrates bait against a wall, through a gap or round the end of a pier makes an edge productive, and slack water frequently switches a mark off. The state of tide at a given mark matters as much as the mark.
AND THE SEASON DIFFERS BY SPECIES AND BY LATITUDE. Squid availability inshore tracks water temperature rather than the calendar, and it varies between years. Cuttlefish are more predictably seasonal because their inshore movement is a spawning migration. Treating either as a fixed calendar event is the commonest planning error.

Check the rules before you fish
Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.
Check with:
- Current national or regional law for where you are fishing
- Current local bylaws
- The relevant fisheries authority
- The landowner, club or fishery whose water it is
- Any restrictions specific to the species or the method you intend to use
