Overview
What is overcapacity?
What is overcapacity?
“Too many people (or boats) and too few fish.”
The amount of fish (or fishing effort) that • can be produced over a period of time
(e.g., a year or a fishing season) • by a vessel or a fleet if fully utilized and • for a given resource condition.
The Jargon
What is overcapacity?
• overinvestment in capital• excessive employment in labour• depleted abundance, overfishing of
targeted stock(s) and associated stocks• reduced returns to capital and labour• decline in quality of life for fishers and
their families • increasing political, management strife
Impacts of Overcapacity
Recognizing Overcapacity
Basic Approaches
Quantitative ApproachesRecognizing
Overcapacity: Basic
Approaches
• Rapid Appraisal (RA) techniques
• Peak-to-peak analysis
• Stochastic Production Frontiers (SPF)
• Data Envelopment Analysis (DEA)
• Biological, Bioeconomic & Multi-objective modelling
FAO Fisheries Technical Paper 433/2
Qualitative Approaches
• Biological status of a fishery declining• Catch per unit effort decreasing• Value per unit effort decreasing • Conflict increasing• Compliance decreasing• Ratios:
– Harvest / target catch exceeding– season length to TAC decreasing
• Other measures – profitability declining– fleet aging– latent permits increasing
