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

Page 5: Patterns of Distribution of Pelagic Seafood on O'ahu ... · Patterns of Distribution of Pelagic Seafood on O'ahu: Preliminary Results from the PFRP Fish Flow Project PFRP Principal

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

Page 6: Patterns of Distribution of Pelagic Seafood on O'ahu ... · Patterns of Distribution of Pelagic Seafood on O'ahu: Preliminary Results from the PFRP Fish Flow Project PFRP Principal

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

Page 12: Patterns of Distribution of Pelagic Seafood on O'ahu ... · Patterns of Distribution of Pelagic Seafood on O'ahu: Preliminary Results from the PFRP Fish Flow Project PFRP Principal

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)

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

Page 27: Patterns of Distribution of Pelagic Seafood on O'ahu ... · Patterns of Distribution of Pelagic Seafood on O'ahu: Preliminary Results from the PFRP Fish Flow Project PFRP Principal

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
