Purpose(s) of end use: Food and feed

Motivation of use: Basic subsistence, Income generation from trade (individual/household/community) and Largescale commercial exploitation for trade

Is this use legal or illegal?: Legal under national law


F. Information about the Users

Which stakeholder(s) does the record primarily focus on?: Local people and National / local government


G. Information about the sustainability of use

Is there evidence that the use is having an impact on the target species?: Wild species sourced from its natural habitat

Has an assessment (or judgement) of sustainability of the use of the target species from an ecological perspective been recorded?: Yes, considered sustainable

Details of assessment carried out: Dept of Fisheries and Oceans Canada (DFO) records

Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Abundance (as measured in kg/tow) of sublegal-sized lobsters as well as number of landed lobsters has been steadily increasing in the study areas since 2012

Has an assessment (or judgement) of sustainability of the use of the target species from an economic perspective been recorded?: Yes, considered sustainable

Details of assessment carried out: This record

Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Sustainable, sold profitably.

Has an assessment (or judgement) of sustainability of the use of the target species from a social perspective been recorded?: Yes, considered sustainable

Details of assessment carried out: This record

Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Traditional practice and food supply where minimum landing size of lobsters and maximum trap window size prevent sub- and super-sized animals to be harvested, maximising breeding success; survival of lobsters released back into the water is high, thus sustainable.

Has an assessment (or judgement) of sustainability of the use of the target species from a human health perspective been recorded?: not recorded

Details of assessment carried out: This study

Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Not recorded

Has an assessment (or judgement) of sustainability of the use of the target species from an animal health/welfare perspective been recorded?: Yes, considered sustainable

Details of assessment carried out: This study

Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Minimum landing size of lobsters and maximum trap window size prevent sub- and super-sized animals to be harvested, maximising breeding success; survival of lobsters released back into the water is high


Recommendations provided in the record to maintain or enhance the sustainability of the use of the target species

Authors state "It would be useful to periodically assess size at 50% size at onset of maturity( SOM50) over the next few decades as the population responds to effects of current management actions and the changing temperature regime (i.e., will SOM50 increase?)."
