Abstract

The sea cucumber species Apostichopus californicus is fished in the Pacific Northwest region of North America and has the potential to be an economically beneficial fisheries species. An understanding of their population levels must be present to sustainably regulate their harvest. Current fisheries in North America vary in their methodology and level of regulation. The current regulations are presented and their strengths and shortfalls are described. This review gathers research done on tropical sea cucumber species and presents that knowledge alongside that regarding Apostichopus californicus to suggest future research and fishery management strategies. A. californicus takes four years to sexually mature and their juvenile survival rates are unknown, so fisheries need to implement strategies that allow adequate time for populations to recover and reproduce. Additionally, strict quotas on the total biomass that can be removed each fishing season need to be set by fisheries. A sustainable fishery can provide many jobs and serve as a sustainable alternative to unsustainable fished species.
