Reproduction and fishing over time
Fishing rules must follow the ability of populations to reproduce and change when scientific assessments indicate a risk.
Research and local documents ↓What the evidence tells us
Cod studies show that fishing pressure, recruitment, and environmental conditions interact. Scientific assessments of the Barents Sea make biomass, catches and uncertainty visible, instead of considering the resource inexhaustible.
Putting the choices into practice

The challengeCatches without biological reference

The challengeUnchanged quotas
The responsePeriodic review
The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
A quota does not guarantee recovery and a stock does not represent all the cod. Climate change and recruitment variability require continuous updates.
Other possible benefits
Greater predictability for communities and activities that depend on the sea.
