Who enforces fishing rules in the UK, and how
Which bodies enforce sea and freshwater fishing rules in Scotland, England, Wales and Northern Ireland, what can happen between a report and a court, and what the published enforcement figures can and cannot tell you.
FishingHQ is not an enforcement body and does not take reports. It explains the rules and points to the authorities that do. Find who to report to
Who enforces what
Sea and fresh water are usually enforced by different bodies, and so are fishing offences and theft. The bodies below are the ones whose own pages FishingHQ read.
Scotland
- Sea:
- The Scottish Government's Marine Directorate, whose fishery officers enforce sea fisheries law, including the recreational bass rules.
- Fresh water:
- District Salmon Fishery Boards and the River Tweed Commission, through the water bailiffs they appoint; the Scottish Government where there is no board; and Police Scotland.
England
- Sea:
- Ten Inshore Fisheries and Conservation Authorities from the shore to six nautical miles, and the Marine Management Organisation.
- Fresh water:
- The Environment Agency, for licences, close seasons, illegal gear and protected fish; the police for theft and fishing without permission.
Wales
- Sea:
- The Welsh Government's Marine Enforcement Officers; prosecutions are brought in the name of the Counsel General.
- Fresh water:
- Natural Resources Wales; the police for theft and fishing without permission.
Northern Ireland
- Sea:
- DAERA, whose online incident system takes reports of illegal fishing; the PSNI for wildlife crime.
- Fresh water:
- DAERA Inland Fisheries, except in the Foyle and Carlingford catchments, where the Loughs Agency is responsible; the PSNI for poaching.
From a report to a court
What can happen after a report
Each stage is a decision by an authority, not a step that follows automatically. Most reports end at the first or second.
Report
Someone tells an authority what they saw. Authorities use reports to decide where to patrol and inspect, as well as to act on a single incident. Most do not tell the person who reported what happened next.
Inspection
Fishery officers, bailiffs or police check catches, gear, licences and boats, on the shore, at sea or at landing. An inspection can find nothing wrong.
May stop here: no offence found, or not enough evidence.
Advice or warning
Where an offence is found, the response is meant to be proportionate. The Welsh Government describes a range that starts with written advice and written warnings.
May stop here: no offence found, or not enough evidence.
Fixed penalty
In Scotland the Marine Directorate can offer a fixed penalty notice instead of prosecution: a civil fine of up to £10,000 for most fisheries offences. If it is not paid, the case is referred to the Crown Office.
May stop here: no offence found, or not enough evidence.
Prosecution
The most serious cases go to the prosecuting authority: the Crown Office and Procurator Fiscal Service in Scotland, and in Wales prosecutions are brought in the name of the Counsel General.
May stop here: no offence found, or not enough evidence.
Court outcome
A court decides whether the offence is proved and, if it is, the sentence. Until then, an accusation is an accusation.
May stop here: no offence found, or not enough evidence.
The same distinction runs through how FishingHQ writes about any case: a report is not an investigation, and an investigation is not a finding.
From a report to an outcome: five stages, none of them automatic
A report can stop at any stage, for good reasons and bad ones. Reaching one stage says nothing about whether the next will follow.
Stage 1
Report
Somebody says an offence is happening, to an authority, a survey or the public.
Stage 2
Investigation
An authority looks into it: visits, inspects, asks questions.
Stage 3
Evidence
Something is gathered that could prove or disprove an offence.
Stage 4
Official finding
An authority decides an offence took place.
Stage 5
Enforcement outcome
A warning, a penalty, a prosecution or a court decision follows.
What the published figures show
Scotland's Marine Directorate publishes how many fixed penalty notices it issues, by kind of offence. One category covers unlicensed and hobby fishing, including breaches of the recreational bass rules from the shore and afloat — and also shellfish limits and gear marking. Between May 2020 and June 2026 it lists 4 notices in that category across Scotland:
| Period | Notices |
|---|---|
| 25 May 2020 to 30 May 2021 | 0 |
| June to December 2021 | 0 |
| January to June 2022 | 0 |
| July to December 2022 | 1 |
| January to June 2023 | 0 |
| July to December 2023 | 2 |
| January to June 2024 | 0 |
| July to December 2024 | 0 |
| January to June 2025 | 0 |
| July to December 2025 | 1 |
| January to June 2026 | 0 |
As listed by the Marine Directorate, last updated 10 September 2026.
What these numbers cannot tell you: where any notice was issued, how many concerned bass rather than shellfish or gear, how many reports or inspections there were, or how many cases were prosecuted instead. A low count is not evidence that offences are rare, and it is not evidence that they are ignored. This page does not yet set out comparable figures for England, Wales or Northern Ireland.
