Species by species
Minimum sizes are indicative (English Channel – North Sea seaboard): only the regulation in force is authoritative. When in doubt, put the fish back.

The rules
Recreational sea fishing requires declaring certain catches. On our seaboard, sea bass, pollack, black seabream and mackerel must be recorded via the free RecFishing app — remember to log your catches after each outing (mandatory from age 16).
Catches over the minimum size must stay whole until landing, to allow checks. The mandatory marking is done by removing the bottom of the caudal fin. Recreational fishing forbids the sale of catches.
Beware of waves and the rising tide on the pier and rock armour; never fish alone in rough weather, and bring non-slip shoes.
The live score
Each species has its own profile: some prefer the flood, others the turn of the tide; some bite mostly at dawn or at night, others in broad daylight; some like a slightly rough sea, others calm water. The score combines, hour by hour: tidal potential (phase and strength of the coefficient, and its trend towards spring or neap tides), light (dawn/dusk/night/daylight, moon phase), sea state (swell, period, wind, direction), the atmospheric-pressure trend, water temperature (and its change over several days), the season and the flow of the Bresle (freshening/turbidity at the mouth). Each factor is calibrated separately for each of the 19 species tracked, then combined into a score out of 10.
This "conditions" score is then adjusted for how present each species actually is at this precise spot (a pier over sandy foreshore, not a rocky mark): a species that is rare here can never reach 10/10 even in perfect conditions, and a near-permanent species keeps a decent score even outside ideal conditions.
It's an indicative index built from local anglers' common-sense rules and real weather/tide data — not a guarantee of a catch, and no substitute for experience at the water's edge.
Gear & bait tip
Need bait or tackle? The shop “Au bord de l'eau”, on the quays at 7 quai François 1er, has everything you need — whether for shore foraging (pêche à pied) or shore fishing.

Tide, sea and weather from Open-Meteo models, recomputed continuously. The fishing index is our own calculation (tide, wind, swell, light, season): a decision aid, not a guarantee of a catch.
The three classic rod-fishing spots are the wooden pier (estacade), the harbour jetty and the beach. Each species on this page shows a live score: the best window depends on tide, swell and light.
From the jetty (estacade), the pier and the harbour quays, or surfcasting on the beach. Each spot suits different species.
No, recreational shore fishing does not require a permit, but it is subject to minimum catch sizes and rules to follow.
Depending on the season: mackerel, sea bass, herring, smelt, sea bream, sole, cuttlefish… A live per-species rating is shown in the fact sheets above.
