1 The spatio-temporal dynamics of fishing behaviour and its determinants in poor fishing communities Nick Hill 1,2 EJ Milner-Gulland 1, Marcus Rowcliffe 2, Guy Cowlishaw 2 1 Imperial College London. 2 Institute of Zoology, Zoological Society of London

2 Outline East Africa and small-scale fisheries Introduction to study site Livelihoods Effects on fishing behaviour

3 East Africa East Africa coastal population 22 million – 5-6% increase per annum Dependence on marine resources. Degradation: serious concern for livelihoods Failure to reduce degradation and poverty – Why?

4 Failure of fisheries management Why the failure? Behaviour poorly understood. Data aggregated spatially Data aggregated across fleet Consequence: Unable to predict response to management Policies and management unsuitable What is needed? Understanding of behaviour and its drivers

5 Study site Vamizi and Rongui Islands

6 Study site Tourism supports conservation and community development The only local development organization

7 Study site The marine resources are in excellent condition.

8 Vamizi Island communities Two community types: –Locals –Transients Each have different livelihoods

9 Hypothesis Livelihoods Fishing behaviour The role of fishing in livelihoods... …spatio-temporal dynamics of fishing: where, when and how much...effects... Fishing behaviour is driven by livelihoods: A livelihood: the capabilities, assets (including social and material resources) and activities required for a means of living. Objectives of fishing

10 Livelihoods Potential roles of fishing in livelihoods:

11 Livelihoods Livelihoods of transient communities? Livelihoods of local communities

12 Effect on fishing behaviour Temporal behaviour: – Frequency of fishing – Length of fishing trips – Investment in gear – Seasonality of fishing

13 Effect on fishing behaviour Environment Travel time Habitat Resource distribution Fishing location Landing sites Spatial behaviour Method: weighted suitability modelling Comparison of weightings for fishermen with different livelihoods Verification with fishing tracks

14 Effect on catch rates p < 0.05 n=22 n=35 n=28

15 Effect on catch rates

16 Conclusion Are spatio-temporal dynamics of fishing behaviour driven by livelihoods? Linking individual fishing behaviour to livelihoods may help us predict the effects of interventions.
