Sustainable Fishing

A practical framework for connecting fisheries data to reliable evidence, measurable sustainability outcomes, and better-informed commercial fishing decisions.

Sustainable commercial fisheries depend on reliable evidence about fish populations, fishing activity, ecosystem health and the effectiveness of management. Buyers, regulators, fishing operators and coastal communities also need confidence that decisions and sustainability claims are supported by credible information.

The eOceans® Sustainable Fisheries Framework helps fisheries, governments, researchers, seafood businesses and industry partners collect, manage, analyze and report data to support responsible fishing, transparent operations and evidence-based decisions.

Six Pillars of Sustainable Fisheries

1. Fish Populations and Biodiversity

Understand the species being caught and the broader marine ecosystems that sustain commercial fisheries.

• Species presence, distribution and composition

• Catch composition and size classes

• Frequency of occurrence and relative abundance

• Changes in species and catch patterns over time

• Bycatch and interactions with non-target species

• Biodiversity and ecosystem indicators

2. Fishing Activity and Harvest Monitoring

Build a clearer picture of where, when and how fishing activity occurs and how it relates to fisheries management objectives.

• Fishing activity and effort

• Catch observations and species composition

• Spatial and temporal fishing patterns

• Fishing grounds and changes in activity

• Catch per unit effort (CPUE), where appropriate

• Monitoring against management measures and reporting requirements

3. Ecosystem Health and Environmental Responsibility

Understand the environmental conditions and pressures that influence fisheries sustainability.

• Habitat condition and distribution

• Interactions between fishing activity and marine ecosystems

• Bycatch and observed wildlife interactions

• Pollution and other environmental pressures

• Habitat disturbance and recovery

• Changes in ecological indicators over time

4. Responsible Fishing and Management Effectiveness

Assess progress toward responsible fishing practices and evaluate whether management actions are achieving their intended objectives.

• Compliance monitoring data and documented observations

• Changes in catch composition and fishing patterns

• Bycatch reduction and mitigation measures

• Spatial or seasonal management measures

• Fishery improvement initiatives

• Progress against sustainability objectives and management indicators

5. Transparency, Traceability and Trusted Evidence

Strengthen confidence in fisheries information through consistent methods, documented data quality and accountable reporting.

• Standardized data collection and reporting methods

• Data validation and quality review

• Documented sources, methods and limitations

• Audit trails and controlled data access

• Evidence sharing among authorized partners

• Clear reporting of findings and changes over time

6. Collaboration and Long-Term Fisheries Stewardship

Bring fisheries stakeholders together around a shared understanding of conditions, priorities and progress.

• Collaboration among fishers, managers, researchers and seafood businesses

• Engagement with coastal and Indigenous communities

• Shared monitoring across fleets, sites and regions

• Reporting for regulators, buyers, funders and stakeholders

• Identification of data gaps and emerging risks

• Adaptive management based on new evidence

How eOceans Powers Sustainable Fisheries

eOceans connects fisheries data workflows, from field observations to analysis and reporting, helping teams turn fragmented information into usable evidence.

• Set up the project. Define fishing areas, target species, methods, variables and monitoring objectives.

• Collect and connect data. Bring together observations, photos, notes and relevant existing datasets from fishing operations, monitoring teams and research partners.

• Check data quality. Use validation, error detection, review and documented workflows to improve consistency and traceability.

• Analyze and map activity and outcomes. Generate maps, summaries and analyses to examine species occurrence, catch composition, relative abundance, fishing patterns and changes over time.

• Report findings. Produce maps and reports for fisheries managers, operators, buyers, partners and other authorized stakeholders.

• Keep evidence current. Add new observations and update analyses and reports as fishing activity and ecological conditions change.

Where the Framework Can Be Applied

The framework can be adapted to a range of commercial fisheries and supply-chain contexts, including:

• Small-scale and industrial fisheries

• Coastal, offshore and deep-sea fisheries

• Wild-capture seafood operations

• Multi-species fisheries and bycatch monitoring

• Fisheries improvement projects

• Ecosystem-based fisheries management

• Collaborative monitoring and co-management

• Seafood procurement and sustainability reporting

• Long-term fisheries and biodiversity monitoring

Measure What Matters

Indicators should reflect the species, fishery, management objectives, available data and applicable requirements. They may include fishing effort, catch composition, size distributions, CPUE, bycatch observations, species occurrence, habitat condition, compliance records and trends over time.

Transparency requires more than collecting data. Results must be interpreted in context, with appropriate sampling methods, documented limitations and safeguards against misleading comparisons. CPUE is not automatically a measure of population abundance, and observational data alone cannot establish stock status or fishing sustainability.

eOceans supports evidence management, analysis and reporting. It does not independently certify fisheries, verify legal catch, replace stock assessments or guarantee seafood traceability. Those outcomes require appropriate methods, authoritative records and independent verification where applicable.

Build Trust Through Better Evidence

Sustainable commercial fisheries need more than sustainability commitments. They need reliable information to understand what is happening, evaluate management, communicate progress and identify where further action is needed.

eOceans helps fisheries stakeholders organize their data, track changes and make evidence more accessible to the people responsible for managing, buying and supporting seafood.

Fish responsibly. Make evidence transparent. Build trust in sustainable fisheries.
