Insight into conflicting claims concerning cod and hake predation on juvenile lobster

Outline 4Internship providers 4Issues 4Literature review åDiet Study åEcological knowledge 4Assessment 4Conclusions / Recommendations

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

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

Hanson & Lanteigne Study ë What did they report? ë Problems with the study: COD Distribution assumptions Sampling depths Sampling timeHAKE Sampling method Sampling depths Sampling time

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

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

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!

St. Georges Bay Ecosystem Project Survey c Questionaire sections: ¶ Attatchment to fishing community · Fishing history of respondents ¸ Experience with harvester organizations ¹ Personal background º local knowledge experts identification

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

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