Study Notes

Sea Around Us Project (Pauly 2016)

Reconstructed historical global fisheries catch data to address gaps in official reporting.
Aims to provide a more accurate representation of global fishery catches and distribution.
Reconstructions indicate significant underreporting of global fish catches.
Data reveal trends and patterns not captured in official statistics.
Project makes data publicly accessible.
Advocates for greater transparency and informed decision-making in fisheries management.

Presentist Bias in Time-Series Data - Fisheries (Zeller 2018)

Emphasis on recent data at the expense of historical information.
Distorts understanding of fish population trends and management effectiveness.
Presentist bias undermines fisheries science and policy.
Calls for incorporating long-term data to inform sustainable fisheries management.

Fisheries and Policy Implications for Human Nutrition (Vianna 2020b)

Fish is a vital source of protein and nutrients for millions of people worldwide.
Overfishing and declining fish stocks threaten human health and dietary diversity.
Sustainable fisheries management is essential for ensuring access to fish.
Need for policies that balance fishery productivity with ecological sustainability.
Fish provides about 3.2 billion people with at least 20% of their average per capita intake of animal protein.

Global Fisheries Science Documents Human Impacts (Zeller 2023)

Sea Around Us Project provides data and insights about human impacts on marine ecosystems.

The 'presentist bias' in time-series data: implications for fisheries science and policy (Zeller, 2018)

Fisheries research often focuses on recent data, neglecting historical information.
This "presentist bias" can distort our understanding of fish population trends and management effectiveness.
Ignoring historical data can lead to misinterpretations of fish stock health and trends.
A more balanced approach to data analysis that includes both historical and contemporary information is needed to improve fisheries science and management practices.

Fisheries and policy implications for human nutrition (Vianna 2020b)

Fish is a vital source of protein and nutrients for millions of people worldwide.
Overfishing and declining fish stocks pose significant threats to human health and dietary diversity.
Sustainable fisheries management is essential for ensuring access to fish as a source of protein and nutrients for millions of people worldwide.
Fish provide about 3.2 billion people with at least 20% of their average per capita intake of animal protein.
Effective fisheries policies and practices that prioritize sustainability and protect marine resources are needed to maintain the benefits that fish provide.

Global fisheries science documents human impacts on oceans: The Sea Around Us serves civil society in the twenty-first century (Zeller 2023)

Human activities have significant impacts on marine ecosystems.
