Overview of Presentation
•
Project rationale, objectives, research methods
•
Background on study areas
•
Preliminary findings, emphasis on spatial aspects of seafood distribution on Oahu
•
Discussion of next steps
Rationale
•
Research need identified at the 2005 PRFP Research Priorities Workshop
•
Examine “Fish Flow”
or “the sources, distribution channels, quantities, end use, and cultural value”
of pelagic and other fish in
island communities around the Western Pacific
•
Contribute to definitions of “fishing community”
in the Main Hawaiian Islands
First Step & Focus of Presentation
•
Do small-place fishing community boundaries make sense in Hawaii, or is the islands-as-communities definition valid?
•
Use case study approach
to examine seafood distribution in local
settings
•
Describe patterns of seafood distribution for:-
One island: Oahu
-
Two communities: Waianae and Haleiwa-
Four “distinct”
fleets:
(1) small boat consumption/recreation-oriented, (2) small boat part-time commercial, (3) small boat commercial, (4) Hawaii longline
Approach/Methods
•
Use social network methods
to identify groups of cooperating fishermen
in each harbor and fleet
•
Establish rapport and trust!
•
Conduct in-depth interviews with highly knowledgeable fishermen about typical
operations & patterns of distribution
•
Focus: document residence patterns, spatial & quantitative aspects of selling, sharing, consuming fish

Harbor & Fisheries Context
•
Harbor: 64 berths; 3 ramps•
FADs: II 11 mi NW; J 14 mi NNE; CO 22 mi W
•
3-4 commercial; 3-4 charter; many part-time commercial
•
Relatively localized
•
Pelagic species especially targeted, some bottom fishing
•
Exposed to trade winds; surface conditions often rough
•
Large winters swells common •
High fuel prices diminished boat fishing activity
•
Harbor: 109 berths; 7 ramps•
FADs: S 4 mi W; R is 5 mi WNW; V 9 mi NW
•
2-3 commercial; 2 charter; many part-time commercial
•
Less localized; many trailered•
Pelagic species especially targeted, some bottom fishing
•
Leeward coast; surface conditions often smooth
•
Some large winter swell events •
High fuel prices diminished boat fishing activity
Identifying the Networks•
Interview harbormasters to identify key fishermen
•
Contact fishers, discuss channels of cooperation/distribution
•
Subsequently contact newly-identified fishermen; repeat
•
Continue until no new persons identified (closed network)
•
Results in binary matrix of actor-to-actor relationships; can be analyzed to determine centrality & connectedness
•
Degree centrality measure
= variance as % of perfect star network of same size where sole node of star is connected to all other actors
(% of a fully centralized network)
Haleiwa Cooperation Network
Degree centrality = 13.5%

Case Study: Distribution of Longline Catch
•
Method: Follow Hawaii-based tuna longline trip from beginning to the end point of distribution of all landings
•
Interview captain during trip about operational & marketing decisions; interview 5 additional captains to validate findings
•
Very small % of damaged or less valuable fish, often mahi, is typically consumed during trip, distributed to crew after
•
Japanese markets not as critical in years past given pricing in continental U.S. markets –
MORE TO COME (captain’s
decision-making processes, local patterns of sale, etc.)
Case: Distribution of Longline-Caught Tuna
Some Preliminary Findings•
Various significant differences between harbors
•
Neither network was highly centralized or closely connected
•
Haleiwa: + sales, + spatial distribution, -
localized residence
•
Waianae: + sharing, + localized residence
•
Sharing extensive and culturally significant all-around
•
Distribution decisions highly contingent (catch, species, motivation, $ . .)
•
“Islands-as-fishing-communities”
appears validated
•
But sub-communities (in this case harbors) are important centers of cooperative activity/venues for localized cultural practices
Next Steps and Challenges
•
Work with interview and other data to relate volumes/values to percentages while avoiding confidentiality/proprietary data problems
•
Further analyze data regarding distribution decision-making
•
Further analyze sociocultural
motives for distribution/use of fish
•
Analyze distribution in terms of direct and generalized reciprocity
•
Consider fish flow in terms of household and regional economies
•
Relate data and analysis to real management issues/decisions
