Fishermen’s Assoc– who/where are they?– what do they do?– Special Projects
Social Research For Sustainable Fisheries– Who was involved?– What was it all about?

ISSUESISSUES
Cod and hake predation on juvenile lobsters Problem
* dissagreement between DFO and fishermen* insufficient research
Use of fish harvesters ecological knowledge My position

AssessmentAssessment
Should Fish harvesters be concerned? Why?
Limited/questionable published data Importance of the lobster fishery Relative abundance of cod and hake in St.
Georges Bay

Ecological KnowledgeEcological Knowledge
Fisheries public policy Collapse of groundfish stocks fishermens concerns ignored
What is ecological knowledge? How can EK be used in fisheries
management? What are some limitations of EK?

Survey ResultsSurvey ResultsWho were identified as local experts?
Active fishermen expertise widely distributed 35 names came up 4 or more times
Characteristics of “experts” slightly more experienced significantly larger boats More licenses

Conclusions/RecommendationsConclusions/Recommendations Select fishermen to be interviewed Focus interviews on details - ie., where & when
to sampleDesign a study based on fishermens’ input &
compensate for weaknesses of diet study sample shallow water spring & summer months method of capture: handlining, gill netting
Request test permit for studyCarry out study - Document findings
