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
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Falling catch per unit effort (CPUE) (but remediated through best practice recommendations).
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: This study reports a complex interaction between ecological, social and economic sustainability. Falling CPUE suggests the available stock of bonitos is being depleted faster than it can renew (ecological population decline). Sociologically, fishers are compensating by making more trips, and even catching more fish than in previous years, but in so doing, their attempts to maintain medium term sustainability for their businesses incurs greater costs, lowers profits, and involves catching smaller, younger fish, which is ultimately likely to worsen the potential for ecological decline. The study then provides recommendations that the authors anticipate would make this bonitos fishery socio-economically sustainable.

Recommendations provided in the record to maintain or enhance the sustainability of the use of the target species
The study suggests educing fishing efforts as a precautionary management approach, calculating that maintaining the status quo level of 2018 levels should maintain stable bonitos stocks and generate optimum economic profits. The port authority could achieve this in part through a moratorium program on new vessel licenses. Fisheries management also needs to improve compliance levels regarding regulations related to the use of fishing gear. Small fish should be released to benefit the fishery in the longer term. Currently, excessive utilization increases total cost, which decrease net profit. If uncontrolled fishing continues, it will lead to the regime of open access-fisheries. It was no longer profitable from a business perspective.
