• Problem
• dissagreement between DFO and fishermen
• insufficient research
• Use of fish harvesters ecological knowledge
• My position

• Sampling time

• HAKE
• Sampling method
• Sampling depths
• Sampling time

Ecological 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?

10
Study Objective

• Collection of background information
• Gather ecological knowledge of fishermen
• identify local experts
• focus group interviews
• individual in depth interviews
• Document
• Design study proposal
• Keep everyone informed!

11
St. Georges Bay Ecosystem Project Survey

• Questionaire sections
• Attatchment to fishing
• community
• Fishing history of
• respondents
• Experience with harvester organizations
• Personal background
• local knowledge experts identification

12
Survey Results

• Who 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

13
Conclusions/Recommendations

• Select fishermen to be interviewed
• Focus interviews on details - ie., where when
  to sample
• Design 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 study
• Carry out study - Document findings
