Ensure effective fishery management and governance is in place

The first step in addressing the impacts of climate change is to improve existing fisheries management, especially where effective management and governance does not yet exist. Without the establishment of best practices for effective management and governance in partnership with fishermen, very little can be done to address climate change effects.

The Pacific sardine fishery off the U.S. West Coast is notorious for wide swings in abundance as a result of changing ecological conditions. Scientific researchers have been able to measure clear and strong correlations between water temperature and stock abundance. This relationship is “lagged,” meaning that a change in water temperature affects the harvestable biomass of sardine in a subsequent time period. By utilizing sardine biomass assessments that account for this environmental variability, managers have developed a science-based harvest control rule that changes the future harvest rate of sardine according to current water temperature indices. The result is effectively a “hard-wired” adaptive management system, based on ecosystem indicators, that helps ensure harvest rates are in line with stock productivity.

Elements of fisheries management best practice include:

Scientifically determined catch limits

Well-defined rights of access

Systems of accountability

Transparent decision-making processes

Adequate enforcement provisions
