Director’s Foreword
In 1497, John Cabot noted on Newfoundland’s cod's abundance. By 1992, a moratorium was imposed on the Northern cod fishery, citing near depletion.
The report reflects on the shifting baseline of fish stocks due to overfishing and its socio-economic impact.
Key Findings:
An estimated loss of US$39 billion in potential landed value annually and 668,479 full-time equivalent jobs (FTE) due to overfishing.
Communities in Latin America and the Caribbean are most affected, followed by Europe and North America.
Emphasizes the urgent need to rebuild overfished stocks for economic and social benefit.
Executive Summary
Objective: To assess the socio-economic impact of overfished stocks:
Estimate potential catch loss from 482 overfished fish stocks.
Calculate the landed value of this catch loss.
Analyze jobs lost associated with the depreciation of these stocks.
Findings:
Annual estimated catch loss: 15 million tonnes globally.
Lost landed value: US$39 billion.
Lost jobs: approximately 668,479 FTE.
Potential job increases exist if all overfished stocks are managed to achieve Maximum Sustainable Yield (MSY).
Introduction
Fisheries contribute significantly to global food security and economies but face threats due to overexploitation.
Historical context: Pre-1990s fisheries peaked at 124 million t.
Major concerns:
Global marine catch currently averages around 112 million t.
37.9 million people employed in fisheries, providing food for 3.1 billion people (20% of their protein).
Drivers of overfishing include excess fishing capacity, poor governance, illegal fishing, among others.
Fish stocks categorized as sustainable declined from 90% in 1974 to 65% in 2019.
The report elaborates on the socio-economic repercussions and highlights catch losses equating to approximately 7-36% of actual landings.
Methodology
4.1. Quantifying Catch Loss
Catch loss defined as the difference between MSY and the last year's catch.
Data from the Sea Around Us database (2018) and Global Fishing Index.
Stocks defined as overfished when biomass is < 40% of unfished biomass.
Analysis includes metrics such as:
MSY: Maximum Sustainable Yield
C: Catch of last year
F/FMSY: Fishing mortality
B/B0: Biomass relative to unfished biomass
4.2. Estimating Revenue Loss
Revenue loss derived from catch loss multiplied by the ex-vessel price of each stock.
Ex-vessel price sourced from over 60,000 prices across different years.
4.3. Estimating Jobs Associated with Catch Loss
Jobs calculated as:
Marine employment data from various sources, incorporating direct and indirect fisheries sectors.
Estimation of catch per fisher to deduce number of jobs linked to catch loss.
Results
5.1. Catch Loss
83% of assessed stocks experienced catch loss totaling 15 million t.
MSY across all overfished stocks was calculated at 28.7 million t.
5.2. Revenue Loss: Landed Value of Catch Loss
Total landed value loss: US$15.4 billion (10% of global fisheries land value).
The top 10 stocks contributed to 41% of total landed value loss.
5.3. Marine Employment Associated with Catch Loss
Total marine employment estimates globally at 13 million FTE fishers with significant concentration in Central and Southern Asia.
Estimated loss of 668,479 jobs associated with catch loss; potential for job gains if stocks are rebuilt.
Discussion and Conclusion
Critical need to establish effective fisheries management to prevent stock collapses.
A significant proportion of fish stocks exceed MSY levels leading to serious socio-economic impacts due to potential job loss.
The report emphasizes rebuilding efforts for overfished stocks as a means to regain lost economic value and employment opportunities.
