Quota Allocation Calculator
About the Quota Allocation Calculator
The Quota Allocation Calculator is a scientifically grounded online tool that distributes Total Allowable Catch (TAC) among fishing vessels using historical catch, vessel capacity, equal share, and hybrid methods as per FAO, EU, and NOAA ITQ guidelines. It computes individual quotas, Gini coefficient for equity, and concentration indices with peer-reviewed accuracy. Developed with support from Agri Care Hub, this tool is trusted by fisheries councils, quota brokers, and researchers worldwide. Learn more in Quota Allocation studies.
Importance of the Quota Allocation Calculator
Fair and transparent quota allocation is critical for ITQ system success, reducing conflict, improving compliance, and preventing fleet consolidation. Historical catch-based allocation rewards past participation, while capacity-based methods favor larger vessels. This calculator instantly generates equitable, defensible quotas — essential for social acceptance, legal compliance, and long-term sustainability. Manual allocation using spreadsheets is error-prone; this tool delivers real-time, auditable results using standard RFMO and ICES allocation frameworks.
User Guidelines
To use the Quota Allocation Calculator:
- Method: Historical, equal, capacity, or hybrid.
- TAC: Total allowable catch in tons/year.
- Vessel Name: Identifier (optional).
- Historical Catch: Average catch over reference period.
- Capacity: Hold size or engine power proxy.
- Add Vessel: Up to 10 entries.
- Calculate: Get quota per vessel, Gini, HHI.
Default: small fleet with varied history and size.
When and Why You Should Use the Quota Allocation Calculator
Use this tool when you need to:
- Implement ITQs: Fair initial allocation.
- Resolve Disputes: Transparent, data-driven shares.
- Assess Equity: Gini and concentration metrics.
- Support Policy: Design allocation rules.
- Teach Fisheries Economics: Demonstrate allocation trade-offs.
It ensures fairness, efficiency, and stakeholder buy-in.
Purpose of the Quota Allocation Calculator
The tool aims to:
- Promote Equity: Reduce allocation conflict.
- Enable Trading: Create fungible quota units.
- Prevent Monopoly: Monitor concentration.
- Support Science: Align with stock assessment.
Scientific Foundation: Allocation Formulas
Historical (Proportional):
Q_i = TAC × (C_i / ΣC)
Capacity-Based:
Q_i = TAC × (Cap_i / ΣCap)
Hybrid (50/50): Q_i = 0.5 × Q_historical + 0.5 × Q_capacity
Equity Metrics
Gini Coefficient: 0 (perfect equality) to 1 (perfect inequality)
Herfindahl-Hirschman Index (HHI): < 1000 (competitive), > 1800 (concentrated)
