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 unsustainable
Details of assessment carried out: This study - based on records of sharks landed at the ports studied.
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: The study laments the lack of reliable longer-term catch data, explaining that this limits any ability to assess sustainability; nevertheless, the catch record clearly showed declining trends and the bulk of the catch was comprised by small sized sharks, likely due to overfishing and lack of gear size limitation. There was a clear indication of change in shark seasonal abundance which might be due to the large exploitation of dog shark during October to December than the previous years. Decreasing in shark species composition was also found which might pose serious threats to shark population and total yield.
Has an assessment (or judgement) of sustainability of the use of the target species from an economic perspective been recorded?: Yes, considered unsustainable
Details of assessment carried out: This study
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: The study expresses concern that although sharks comprise an important part of this regional fishery, supporting livelihoods, local economics and food security, in all likelihood dog (and other) sharks were being over-exploited, which could ultimately undermine sustainability. Current fishing gear limitations and the size of vessels also limits artisanal fishing to smaller sharks in inshore waters, where dog sharks predominate - further increasing their vulnerability to over-exploitation.
Has an assessment (or judgement) of sustainability of the use of the target species from a social perspective been recorded?: Yes, considered unsustainable

Recommendations provided in the record to maintain or enhance the sustainability of the use of the target species
The study concludes that steps should be taken to ensure maximum sustainable yield and conservation through the inclusion of sharks in the [Bangladesh] Fish Act, restricting overexploitation or illegal exploitation.
