Monitoring, Control, Surveillance

The three-pillar model every fisheries-tech term you'll meet is a piece of — and where e-Boat sits inside it.

Start with the problem, not the acronym. Fish stocks are a shared, depletable resource. If nobody checks who is fishing, where, and how much, the resource collapses — that's the textbook tragedy of the commons at sea. IUU fishing (Illegal, Unreported, Unregulated) is the umbrella term for the ways that check fails: someone fishing where they're not licensed to (illegal), someone catching fish and not declaring it (unreported), or someone fishing a stock or area with no rules at all (unregulated).The "IUU" acronym bundles three legally distinct failures — worth keeping separate, since e-Boat's violation catalogue will eventually need to say which one it caught.

Every fisheries control system in the world — e-Boat included — exists to make that check possible at scale. The standard way to describe the system is MCS:

1. MonitoringCollecting the raw facts: where is the vessel, what is it catching, how much effort is it expending.
2. ControlSetting the legal terms of harvest ahead of time: licences, quotas, closed areas, gear rules. This is law and policy, not software — but software has to encode it.
3. SurveillanceChecking monitoring data against control rules, and acting when they don't match: an inspection, a violation record, a notification, a licence suspension.

The instrument that makes Monitoring possible: VMS

VMS (Vessel Monitoring System) is shipboard equipment that reports a vessel's position — usually by satellite — to a fisheries authority at a set interval. It's worth noticing what kind of thing it is: not just a GPS tracker, but a licence condition. In most regimes, carrying a working, transmitting VMS unit is a legal requirement to hold a fishing licence at all — see FAO's 2000 legal paper on satellite-based VMS, which frames it exactly this way.

VMS is easy to confuse with AIS (Automatic Identification System), which also broadcasts vessel position by satellite/radio. The difference is purpose and access, not technology:

A third instrument, ERS (Electronic Reporting System), is the electronic version of the paper catch logbook: it reports what was caught, not where the vessel is. VMS and ERS are separate obligations that a complete national system has to carry, sometimes in separate software. That split shows up directly in Ukraine's architecture: eFish (live since 2024) owns permits, logbooks and landing declarations — the ERS/licensing half — while e-Boat owns the live position map and violation detection — the VMS half. That's why e-Boat's README lists e-fish as an external REST consumer rather than something e-Boat re-implements.
