What success looks like (5–10 years)
• Fishing mortality aligned with species’ life histories
• Species-level reporting becomes the norm
• Management completeness rises above critical thresholds
• Shark & ray populations stabilize and recover

• 40% of global shark & ray catch comes from low- and middle-income countries
• Small-scale fisheries underpin livelihoods and food security
• Under-resourced management = high biodiversity & social risk
• Reduced fishing mortality reduces extinction & social risk, improving ecosystem functions.

Where investment has the highest leverage to bend back biodiversity loss?

Funding that strengthens:
• Species-level catch & trade data
• Compliance and enforcement
• Capacity in national agencies
• Monitoring in small-scale fisheries
→ Directly reduces fishing mortality

We don’t need new frameworks — we need to connect and implement the ones we have.

Fisheries management, trade rules, compliance, and demand must align to reduce fishing mortality at scale.
Implementation is the bottleneck.

Decline is not inevitable.

Where fishing mortality has been reduced — through catch limits, retention bans, or spatial protection — shark and ray populations are stabilizing or recovering.

Gaps in catch limits, compliance, and enforcement mean fishing mortality stays high even where policies exist.

Where management is complete, risk is lower and recovery is possible.

Overfishing is compounded by under-management

Fishing mortality is the primary driver &
management completeness (for guitarfishes & requiem sharks) stands at ~49% globally.

What’s driving the decline?

The crisis isn’t just fishing — it’s invisible fishing.

Much shark & ray catch is under-reported, aggregated, or mislabeled, masking real mortality & delaying management.

What we don’t measure, we don’t manage.

Sharks & rays are sentinels of ocean health.

- Global abundance has been fished down by 65%,
- Now 37.5% of species are threatened,
- The current extinction rate is 25–250 times greater than the background fossil record, with greatest losses in tropical coastal seas. #BiodiversityTargets

Healthy and sustainable fisheries have lower carbon emissions and fuel use, because fish are more abundant and easier to catch with less effort. Rebuilding fisheries and ensuring that fleet sizes are appropriate for catch level, are keys for CO2 reduction

Ongoing disclaimer:
I'm feeling just as anxious, angry & horrified as *anyone with a basic sense of empathy & compassion* right now.

My coping mechanism is sharing weird little guys & science threads with you.

If it feels like I'm not reflecting the tone of this moment, that's a purposeful choice.
