Hold live quota balances on a shared network. Every catch record updates the balance through the Logic and Actions Editor, and Compliance Attestations and Notifications flag a vessel the moment it nears its limit, so overfishing is prevented at the structural level.
Turn impossible manual monitoring across a fleet into a live quota ledger that enforces itself.
01.
Hold every allocation on-chain. The shared network tracks each vessel's remaining quota in real time, replacing manual monitoring that cannot scale across hundreds of boats.
02.
Update the balance at each landing. Every catch record decrements the vessel's quota through the Logic and Actions Editor, so the ledger always reflects true remaining allowance.
03.
Warn before the breach. Notifications flag a vessel the moment it nears its quota, giving the operator and authority time to act before overfishing occurs.
04.
Block offloading over quota. A vessel that exceeds its limit is flagged and blocked at port before it can offload, stopping overfishing at the structural level.
05.
Prove each vessel's standing. Compliance Attestations record whether each boat stayed within quota, building a verifiable record for licensing and enforcement.
06.
Generate reports in minutes. The authority compiles a full season compliance report directly from the ledger instead of reconciling paper logs across the fleet.
Follow one season from quota allocation through catch deductions to a vessel blocked at port for exceeding its limit.

Cerulea decomposes quota compliance into modular contracts for allocation state, catch deduction, limit alerts, and port enforcement, so overfishing is stopped before it lands.
Quota compliance is a horizontal capability. Here is how authorities, ports, and operators put one live ledger to work.
Monitor a whole fleet against quota in real time and generate a season compliance report in minutes instead of reconciling paper logs across hundreds of vessels.
Key Asset Types
Enforce quota at the point of offload, blocking a vessel that exceeds its limit before its over-quota catch can enter the supply chain.
Key Asset Types
See remaining quota live and receive alerts before nearing the limit, staying compliant and protecting the licence rather than risking revocation.
Key Asset Types
Whether an authority is bridging a licensing system or a vessel is reporting a landing from sea, Cerulea routes both into one quota ledger.

Live Quota Record
Building a live quota ledger with catch-linked deduction, approaching-limit alerts, and port-level enforcement from scratch requires fisheries and blockchain engineers and long fleet integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects fisheries monitoring integration benchmarks. Building live quota balances, catch deduction, limit alerts, and port enforcement for an average fleet takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your quota and enforcement rules into pre-audited WebAssembly binaries and provisions the shared ledger and notification layer instantly.
