How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish thick-lipped grey mullet in United Kingdom
- Spring 1–15 ft — Use a quiet approach and light tackle around warming walls and mud margins.
- Summer 1–18 ft — Sight-fish individuals or small groups; heavy groundbait and tackle can spook them.
- Fall 2–22 ft — Focus on sheltered, sun-warmed reaches before fish move toward the coast.
- Winter 8–35 ft — Most mullet are scarce or inactive in cold estuary water; do not treat winter observations as a dependable fishery.
