Interactions between artisanal fishers and industrial vessels
TDW-11: th April 2017, Noumea, New Caledonia

2. Overview Introduction to me and my work Main event: Approach
Data & modelling
Results
Implications

3. Introduction to Phil
FAD monitoring using artisanal data and Tails+ with additional fields
Household surveys
Economic analysis of fishery policy options and coastal fisheries data
Bio-economic analysis of non-tuna related species

4. Approach
Most literature reviews interactions within the fisheries stock
A different approach:
“how does the presence of the industrial fishery impact the artisanal fishers willingness to go fishing”

5. Data & Modelling
Discrete choice model:
log(µ) = α + βx

6. Results Number of artisanal vessels fishing
Presence of industrial vessels has a significantly negative impact on willingness to go fishing of artisanal fishers
Weather?

7. Results Catch per unit of effort
Presence of industrial vessel does appear to reduce artisanal catch rates
Why this happens we are unclear, it could be a stock issue as stocks take a long time to recover after a large removal or it could be more experienced fishers stay at home and do not go fishing and so there is a consequential decline in CPUE. We however do not have the data to support a conclusions either way – a point of further research perhaps. Or weather

8. Implications Over the period of 4 years we estimate:
2,200 artisanal fishing days lost
Over 5,000 lost days of employment
676 tons of fish were not landed by artisanal vessels
11,500 person years of fish consumption were lost
USD2.7m in revenue to artisanal fishers lost

9. Context
Employment; transshipping brought at least twice the number of lost days of employment to the port
The ‘lost catch’ is close to or slightly greater than off loads
Revenue (Gillett 2016):
SI earn $27m from license fees,
Tuvalu 85% of government revenue is from license fees and
Marshall Islands $17m is for access rights in 2014

10. Future analysis Further analysis required
In-depth investigation of the reasons behind the findings e.g. moon phase/weather patterns
Survey to understand the value of the activities to the wider economy
Continued and improved data collection to capture these impacts in other ports
