Fishing Gear Impact Calculator
About the Fishing Gear Impact Calculator
The Fishing Gear Impact Calculator is a scientifically validated online tool that quantifies Fishing Gear Impact on marine ecosystems using habitat disturbance, bycatch mortality, ghost fishing, and carbon footprint models from Kaiser et al. (2006), Gilman et al. (2020), and FAO guidelines. It computes an overall Impact Score (0–100) with full transparency and mitigation analysis. Developed with support from Agri Care Hub, this tool is trusted by fisheries managers, NGOs, and gear manufacturers worldwide.
Importance of the Fishing Gear Impact Calculator
Fishing gear is the primary interface between fisheries and marine ecosystems. Trawls disturb benthic habitats, gillnets cause ghost fishing, longlines hook seabirds — all contribute to biodiversity loss and carbon emissions. This calculator uses peer-reviewed impact factors to benchmark gear performance — essential for EBFM, MSC certification, and carbon-neutral fishing. Manual impact assessment is complex; this tool delivers instant, defensible results using standard ICES, NOAA, and IUCN protocols.
User Guidelines
To use the Fishing Gear Impact Calculator:
- Gear Type: Select trawl, gillnet, etc.
- Fishing Days: Annual operation.
- Sets per Day: Hauls or deployments.
- Gear Loss: % of gear lost annually.
- Seabed Area: For trawls (ha/year).
- Mitigation: Check BRD, TED, biodegradable, tracking.
- Calculate: Get Impact Score and breakdown.
Default: bottom trawl with 5% loss.
When and Why You Should Use the Fishing Gear Impact Calculator
Use this tool when you need to:
- Reduce Habitat Damage: Switch to lighter gear.
- Minimize Bycatch: Install BRDs/TEDs.
- Prevent Ghost Fishing: Use biodegradable panels.
- Achieve Certification: MSC, FIP requirements.
- Lower Carbon Footprint: Optimize fuel use.
It ensures sustainability, compliance, and transparency.
Purpose of the Fishing Gear Impact Calculator
The tool aims to:
- Quantify Impact: From seabed to atmosphere.
- Drive Innovation: Test mitigation efficacy.
- Support Policy: Evidence-based gear rules.
- Raise Awareness: Educate fishers and consumers.
Scientific Foundation: Impact Scoring
Overall Impact Score:
I = w₁H + w₂B + w₃G + w₄C
Weights: H=0.3, B=0.3, G=0.2, C=0.2
Impact Components
Habitat (H): Trawl penetration depth
Bycatch (B): Species vulnerability × mortality
Ghost Fishing (G): Lost gear × catch rate × duration
Carbon (C): Fuel use per kg catch
Advanced Outputs
The tool provides:
- Overall Impact Score (0–100)
- Breakdown: Habitat, Bycatch, Ghost, Carbon
- Mitigation savings (%)
- Interactive radar chart
- Recommendations
Real-World Applications
Gear impact is used in:
