E. Information about the use
How is the wild species sourced?: Wild species sourced from its natural habitat
Type of use: Extractive
Practice of use: Targeted fishing harvesting/exploiting or collecting wild aquatic resources
Lethal or non-lethal: Lethal
Does this use involve take/extraction of: The whole entire organism
Purpose(s) of end use: Food and feed
Motivation of use: Basic subsistence and Income generation from trade (individual/household/community)
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
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?: No, sustainability not determined
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 study
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Authors emphasise, however, that ecological sustainability of current harvest levels in general, nor of each of the 3 harvest methods specifically, hneeds to be ascertained through population assessment and monitoring. They emphasise that: "An update of the 2017 Fisheries Agreement will need to account for a range of ecological and economic trade-offs and of the shellfish collection technique employed in the area. Ecologically, economically and socially meaningful management strategies will help to achieve key Sustainable Development Goals, including an ‘Improvement of Life Under Water’ (Goal 14) through sustainable resource management"

Recommendations provided in the record to maintain or enhance the sustainability of the use of the target species
Authors advocate the need of future studies determine age/size of sexual maturity of the local A. flexuosa stock and the abundance of mature specimens to assess whether the current dipnet mesh (and grading size) is sustainable. Furthermore, rules should be included regarding the ecologically appropriate locations for return of undersized clams (i.e. intertidal or shallow infralittoral zones.). They further suggest a comprehensive assessment of the dynamics of the in all fishing areas and, depending on the availability of such sites, in unfished control areas. They emphasise that, to establish ecologically and socially adequate quota, it will also be necessary to determine collecting-technique specific yields locally.
